2020 Hypothetical Pacific Typhoon Season (Sebastian's Version)

The 2000 What-might-have-been Pacific Typhoon Season was an above average season. It was the first year STCC West Pacific was introduced after being finished on April 1, 2000. The first storm formed on May 3 and the last storm dissipated on January 7, 2001. The strongest storm of the season was Super Typhoon Bopha (Ningning) that peak with 10-min winds of 130 mph (215 km/h) and a minimum pressure of 903 mbars (26.66 inHg). There were 36 depressions, 31 named storms, 17 typhoons, and 4 super typhoons. The costliest storm of the season was Super Typhoon Yagi (Ulpiang) which caused $11 billion (2000 USD) in the areas it affected and damaged. The deadliest storm of the season was also Super Typhoon Yagi (Ulpiang) which killed 231 people in the areas it affected and damaged. The longest lasting storm was even Super Typhoon Yagi (Ulpiang) which lasted for 14 days. The season was an ordinary season. Two systems crossed into the Central Pacfic; 17W and Saomai.

Super Typhoon Damrey (Asiang) (01W)
On May 3 at 18:00 UTC, the JMA monitored a tropical depression southeast of Palau while the JTWC named the depression Tropical Depression 01W, becoming the first depression of the season. The depression moved north at first but near the end of the next day, May 4, it moved northwest due to a high pressure area over the Mariana Islands. The next day, May 5, it was named "Asiang" by PAGASA. It continued northwest and on May 6 at 06:00 UTC, the depression intensified into a tropical storm according to the JMA and JTWC and was given the first name on the new Asian list, Damrey, becoming the first Asian named storm and first named storm of the season. The next day, May 7, the JMA upgraded Damrey to a severe tropical storm. Later that day, the JTWC upgraded Damrey to a Category 1 typhoon. The next day, May 8 at 00:00 UTC, the JMA and PAGASA upgraded Damrey to a typhoon. Later that day, the JTWC upgraded it to a Category 2 typhoon then a Category 3 six hours later. The next day, May 9 at 00:00 UTC it rapidly strengthened to a Category 4. Then twelve hours later, it was upgraded to a super typhoon by the JTWC and became a Category 5 the next hour, becoming the first super typhoon of the season. Six hours later, Damrey reached its peak intensity with 1-minute winds of 295 km/h (180 mph). It maintained Category 5 strength for 24 hours. Then, the next day, May 10, Damrey underwent an eyewall replacement cycle and weakened to a Category 4 super typhoon, being downgraded to a Category 4 typhoon a few hours later by the JTWC. Early on May 12, it weakened even further into a Category 3 typhoon as it passed over the Ogasawara Islands. It maintained Category 3 intensity until May 13 at 12:00 UTC when it underwent extratropical transiton and rapidly weakened to a Category 2 typhoon and a Category 1 six hours later. Early the next day, it became extratropical. It dissipated later that day.

In Palau, when Damrey was in its tropical depression stage, it dumped torrential rainfall over Palau up to 340 milimeters of rainfall but no damages and deaths occured. In the Ogasawara Islands, Damrey passed over as a Category 3 typhoon, uprooting trees but minimal damage and no deaths occured. Despite this, it caused minimal damage only in the areas it affected and damaged.

Tropical Storm Longwang (Biring) (02W)
On May 17 at 06:00 UTC, both the JMA and JTWC monitored on a tropical depression which formed over Cagayan province. PAGASA then followed suit on the same time and named it "Biring". A few hours later, it moved offshore. The JTWC named the depression Tropical Depression 02W. The next day, May 18, both the JMA and JTWC noticed that the depression strengthened into a tropical storm and was given the next name on the list, Longwang, becoming the second named storm of the season at 12:00 UTC. 24 hours later or on May 19 at 12:00 UTC, Longwang reached its peak intensity with 1-minute winds of 60 mph (95 km/h). Then, its movement increased and started to weaken due to cooling sea surface temperatures and increasing wind shear. On May 20 at 06:00 UTC both the JMA and JTWC noticed that Longwang weakened to a tropical depression. Then six hours later, both agencies noticed that Longwang dissipated.

In the Philippines, Biring brought heavy rainfall over northern Luzon causing PAGASA to raise Signal No. 1 warnings over Cagayan, Batanes, Babuyan Group of Islands, Ilocos Norte, Abra, Kalinga, Isabela, and Mountain Province. A person was killed indirectly from leptospirosis on May 24. In the Ryukyu Islands, heavy rainfall was experienced in Miyako-jima and places in Longwang's closest approach to the Ryukyu Islands. In the Ogasawara Islands, nothing bad happened. Only moderate to heavy rainfall. The system caused $30,000 (2000 USD) in the areas it affected and damaged.

Tropical Storm Kirogi (Konsing) (03W)
On May 20 at 06:00 UTC, both the JMA and JTWC monitored on a depression moving east-southeast. The JTWC upgraded it to Tropical Depression 03W, becoming the third depression of the season. PAGASA then saw a depression west of Ilocos Norte and was named “Konsing” by PAGASA. But, after 18 hours 03W moved northeast due to an interaction with a frontal system. On May 22 at 00:00 UTC, the depression was upgraded by the JMA, JTWC, and PAGASA to a tropical storm and was given the next name on the list, Kirogi, becoming the third named storm of the season. It only remained a tropical storm for 30 hours and had its peak intensity with 1-minute winds of 40 mph (65 km/h). The next day, May 23, it was absorbed by an extratropical cyclone over Japan.

In the Philippines, Konsing affected the areas affected by Biring (Longwang). Signal #2 was raised in Batanes. Signal #1 was raisd in the Babuyan Group of Islands, Cagayan, and Ilocos Norte. Heavy rainfall occured in Cagayan and Batanes. In the Ryukyu Islands, heavy rainfall ocured in Miyako-jima after being affected by Longwang. No deaths occured also. The system caused $15,000 in all the areas it affected and damaged.

Tropical Storm Kai-tak (04W)
On May 30, both the JMA and JTWC monitored on a depression west of Vietnam. The JTWC upgraded it to Tropical Depression 04W, becoming the fourth depression of the season. On June 1 at 00:00 UTC, both agencies upgraded 04W to a tropical storm and the JMA gave the system the next name on the list, Kai-tak, becoming the fourth named storm of the season. But 12 hours later, it weakened to a tropical depression before making landfall over Quat Lam, Vietnam. It moved inland before dissipating the next day, June 2 over Yunnan, China.

In Vietnam, heavy rainfall occured in the eastern part of the country, killing 14 people; 13 direct, 1 indirect. In Hainan, tropical storm force winds and heavy rainfall occured over the western part of the island, killing 12 people; 4 direct, 8 indirect. In Laos and China, torrential rainfall occured, killing 6 people; 4 in Laos, 2 in China; all direct. The system caused $3 million (2000 USD) in all the areas it affected and damaged.

Tropical Depression 05W (Ditang) (05W)
On June 16, the JMA, JTWC, and PAGASA monitored on a depression west of Luzon in the Philippines. The JTWC named it Tropical Depression 05W, becoming the fifth depression of the season while PAGASA named it "Ditang". The STCC (an agency which monitors cyclones worldwide, only in HHW) expected it to strengthen into a tropical storm and be named Tembin but it turned north due to a high pressure area over Vietnam. On June 17, 05W made landfall over Hong Kong, China. It dissipated the next day, June 18.

In the Philippines no warnings were in effect but it started the southwest monsoon in the Philippines and PAGASA was forced to declare the start of rainy season on June 16, a few hours after "Ditang" formed. In China, Hong Kong experienced heavy rainfall. In Macau, there were 4 deaths; 3 direct due to drowning, 1 indirect due to leptospirosis in floods. In most of Guangdong, there weren't many effects felt except for moderate to heavy rainfall. The system caused $200,000 in all the areas it affected and damaged.

Typhoon Tembin (Edeng) (06W)
On July 2 at 12:00 UTC, the JMA, JTWC, and PAGASA all monitored on a depression east of the Philippines. The JTWC named it Tropical Depression 06W while PAGASA named it "Edeng". The next day, July 3 at 00:00 UTC, the depression was upgraded to a tropical storm by the JTWC. A few hours later, the JMA upgraded it to a tropical storm and was given the next name on the list, Tembin, becoming the fifth named storm of the season. A few hours later, PAGASA upgraded "Edeng" to a tropical storm. Later that day, the JMA upgraded Tembin to a severe tropical storm. On July 4 at 00:00 UTC, the JTWC upgraded Tembin to a Category 1 typhoon. 6 hours later, both the JMA and PAGASA upgraded Tembin and "Edeng" to a typhoon, becoming the second typhoon of the season. 12 hours later, the JTWC upgraded Tembin to a Category 3 typhoon, a sign of rapid intensification. 6 hours later, the JTWC upgraded Tembin even further to a Category 4 typhoon. Then, it turned northeast. On July 5 at 06:00 UTC, Tembin reached its peak intensity with 1-minute winds of 145 mph (230 km/h). A few hours later, PAGASA issued their final advisory on "Edeng" after it left PAR. On the next day, July 6 at 18:00 UTC, Tembin underwent an eyewall replacement cycle. The next day, July 7, at 12:00 UTC, the JTWC downgraded it to a Category 3 typhoon. It then moved north at a fast speed. The next day, July 8 at 06:00 UTC, it rapidly weakened to a Category 1 typhoon according to the JTWC. On the same day at 11:00 UTC, it made landfall near Erimo, Hokkaido in Japan. An hour later, both the JMA and JTWC declared the typhoon extratropical, releasing their final advisories. The extratropical remnants were absorbed by another extratropical cyclone the next day, July 9 at 00:00 UTC.

In the Philippines, Tembin enhanced the southwest monsoon in the Philippines, bringing heavy rainfall over Luzon and Visayas, killing 2 people indirectly from diseases. In the Ryukyu Islands, large swells and rip currents occured but no deaths were reported. In Japan, this was the hardest hit mostly in Hokkaido where torrential rainfall brought flooding and strong winds uprooting trees, killing 16 people directly. In the Ogasawara Islands, its outer rainbands brought heavy rainfall over the northernmost part of the islands, killing a person directly from drowning in flooding. In the Kuril Islands, heavy rainfall occured, killing 5 people directly from uprooting trees. The system caused $850 million (2000 USD) in all the areas it affected and damaged.

Typhoon Bolaven (Gloring) (07W)
On July 3, the JMA, JTWC, and PAGASA monitored on a depression west of the Philippines. The JTWC named it Tropical Depression 07W, becoming the seventh depression of the season while PAGASA named it "Gloring". 07W (Gloring) made its first landfall over Ilocos Norte, Philippines while moving northeast. On July 4 at 18:00 UTC, 07W strengthened to a tropical storm and was given the next name on the list, Bolaven, becoming the sixth named storm of the season. The JMA and PAGASA upgraded it to a tropical storm. It then moved westwards due to an interaction with Typhoon Tembin but it continued strengthening despite the interaction. On July 5 at 06:00 UTC, the JMA upgraded Bolaven to a severe tropical storm. Then, on the same day at 12:00 UTC, the JTWC upgraded Bolaven to a Category 1 typhoon. Then, the JMA and PAGASA upgraded it to a typhoon, becoming the third typhoon of the season. Bolaven then turned northeast as it completed a loop. The next day, July 6 at 06:00 UTC, the JTWC upgraded Bolaven to a Category 2 typhoon. 12 hours later, the JTWC upgraded Bolaven even further to a Category 3 typhoon as it moved northwest towards China. PAGASA issued their final advisory as "Gloring" left PAR. On July 7 at 12:00 UTC, Bolaven was upgraded more by the JTWC to a Category 4 typhoon. On July 8 at 00:00 UTC, it reached its peak intensity with 1-minute winds of 140 mph (220 km/h) and made landfall near Quanzhou, Fujian, China. Bolaven then rapidly weakened to a Category 1 then to a tropical storm in 12 hours. It then weakened to a tropical depression and dissipated the next day, July 9.

In the Philippines, when "Gloring" formed, Signal #1 warning wwere issued in Regions I, II, CAR, and parts of Region III. When "Gloring" was upgraded to a tropical storm, Signal #3 warnings were issued in Batanes while Singal #2 warning extended into parts of Regions I, II, and CAR. Signal #1 warnings extended south until Bataan. When "Gloring" was upgraded to a typhoon, Signal #3 warnings extended south to Ilocos Norte and Northern Cagayan. Signal #2 warnings extended south to Pampanga. Signal #1 warnings extended south to Laguna. Gloring enhanced the southwest monsoon in the Philippines, killing 10 people directly. In Taiwan, the slow movement of Bolaven brought torrential rainfall and gusty winds in the western part of the country, killing 24 people; 18 directly due to flying debris and drowning in floods, and 6 people due to leptospirosis. In China, Fujian was the hardest hit, with 140 mph (220 km/h) winds in its eyewall after landfall and torrential rainfall, killing 32 people directly. The system caused $1.4 billion (2000 USD) in all the areas it affected and damaged.

Tropical Storm Chanchu (Huaning) (08W)
On July 11 at 06:00 UTC, the JMA, JTWC, and PAGASA all monitored on a depression that formed east of Samar Island. The JTWC assigned it Tropical Depression 08W while PAGASA named it "Huaning". It maintained tropical depression intensity due to moderate wind shear. On July 14 at 06:00 UTC, 08W (Huaning) made landfall over Maria Aurora, Aurora in the Philippines. It maintained its intensity while crossing Luzon. Later that day it moved offshore. The next day, July 15, PAGASA issued their final advisory on "Huaning" as it left PAR. On July 16 at 12:00 UTC, the JMA and JTWC upgraded 08W to a tropical storm and was given the next name on the list, Chanchu, becoming the seventh named storm of the season. 6 hours later, Chanchu reached its peak intensity with 1-minute winds of 40 mph (65 km/h). On July 17 at 00:00 UTC, Chanchu made landfall over Macau, China at peak intensity. Chanchu then weakened to a tropical depression and then moved north. It dissipated on the same day at 18:00 UTC.

In the Philippines, when "Huaning" affected the Philippines as a tropical depression, Signal #1 warnings were issued in Regions I, II, CAR, III, NCR, 4A, most of Region V and Samar Island. It enhanced the southwest monsoon, killing 24 people;  13 direct, 11 indirect. In China, Macau was the hardest hit with tropical storm force winds and torrential rainfall, killing 16 people directly from drowning in floods. The system caused $10.2 million (2000 USD) in all the areas it affected and damaged.

Tropical Depression 09W (Isang) (09W)
On July 15 the JMA, JTWC, and PAGASA monitored on a depression that detached from a monsoon trough over the Philippines. The JTWC named it Tropical Depression 09W, becoming the ninth depression of the season while PAGASA named it "Isang". On July 16, PAGASA issued their final advisory as "Isang" left PAR. 09W failed to strengthen to a tropical storm due to strong wind shear from Tropical Depression 08W (which later became Tropical Storm Chanchu). On July 18 at 00:00 UTC, 09W made landfall over Houhai Lake, Guangdong in China. It dissipated later that day 12 hours later.

In the Philippines, despite no PSWS, it enhanced the southwest monsoon, bringing torrential rainfall in the Visayas and Southern Luzon, killing 4 people; 3 direct, 1 indirect. In Vietnam, its outer edges brought heavy rainfall, killing 2 people directly. In China, Guangdong was the hardest hit with houses being damaged in floods and power outages, killing 6 people directly. Despite this, minimal damage occured.

Typhoon Jelawat (10W)
On July 17 at 06:00 UTC, the JMA and JTWC monitored on a depression over the Ogasawara Islands. The JTWC named it Tropical Depression 10W. On July 18 at 00:00 UTC, the JTWC upgraded 10W to a tropical storm. The JMA followed suit later and gave it the next name on the list, Jelawat, becoming the eighth named storm of the season. It moved north-northwest generally. On July 19 at 00:00 UTC, the JMA upgraded Jelawat to a severe tropical storm. 12 hours later, the JTWC upgraded it to a Category 1 typhoon. 6 hours later, the JMA upgraded Jelawat to a typhoon, becoming the fourth typhoon of the season. It then turned northeast towards the Kanto region. On July 20 at 06:00 UTC, Jelawat reached its peak intensity with 1-minute winds of 85 mph (140 km/h). Jelawat weakened slightly just before making landfall over Chiba in the Kanto region in Japan. The JTWC downgraded Jelawat to a tropical storm. It weakened to a severe tropical storm soon after according to the JMA a few hours later. 6 hours later, the JTWC downgraded Jelawat to a tropical storm due to cooling sea surface temperatures. On July 21 at 12:00 UTC, the JTWC downgraded Jelawat to a tropical depression while the JMA followed suit later, doing the same thing. It dissipated 18 hours later.

In the Ogasawara Islands, heavy rainfall occured and tropical storm force winds occured, uprooting trees, and damaging structures but no deaths occured. In Japan, the Kanto region was the hardest hit, most especially Chiba with hurricane force winds, torrential rainfall, and flash flooding, killing 3 people directly from flash floods. The system caused $1 million (2000 USD) in all the areas it affected and damaged.

Severe Tropical Storm Bilis (Lusing) (11W)
On July 17 at 06:00 UTC, the JMA, JTWC, and PAGASA monitored on a depression in the Philippine Sea that just developed from a disturbance that detached from a monsoonal trough on July 13 near Guam. The JTWC named it Tropical Depression 11W, becoming the eleventh depression of the season while PAGASA named it "Lusing". The depression moved northwest towards the Philippines. It was expected to make landfall but a high pressure area in the South China Sea forced it to move north and then northeast, still as a tropical depression. On July 21, PAGASA issued their final advisory as "Lusing" left PAR. On July 23 at 06:00 UTC, the depression strengthened to a tropical storm according to the JTWC and JMA and was given the next name on the list, Bilis, since Ewiniar was given to 12W since it strengthened to a tropical storm first, becoming the tenth named storm of the season. It noved north then to the west. Continuing to strengthen, on July 24 at 18:00 UTC, Bilis strengthened to a severe tropical storm according to the JMA with 1-minute winds of 65 mph (100 km/h). 6 hours later, it reached its peak intensity. Bilis then started to weaken due to cooling sea surface temperatures and increasing wind shear and on July 26 at 06:00 UTC, Bilis was downgraded to a tropical storm by the JMA and then moved north shortly afterward. The next day, July 27, at 12:00 UTC, Bilis weakened to a tropical depression accoridng to the JTWC and JMA. On July 28 at 00:00 UTC, Tropical Depression Bilis made landfall over Jeju Island, South Korea as a tropical depression. Then, six hours later, it made another landfall over Gyeongnam, South Korea. It then dissiapted on the same time it made landfall.

In the Philippines as "Lusing" neared Luzon, Signal #1 warning were issued in Regions I, II, CAR, most of Region III, Catanduanes, and Polillo Island in Quezon. It enhanced the southwest monsoon, bringing torrential rainfall and flash floods across Luzon and Western Visayas, killing 1 person directly. In the Ryukyu Islands, it brushed all the islands but the Amami Islands were the hardest hit with tropical storm force winds killing 2 people; 1 direct, 1 indirect. In Japan, Kyushu also experienced tropical storm force winds which killed 2 people directly from flash floods. In South Korea, heavy rainfall occured in Jeonnam and Gyeongnam but no deaths occured. Despite this, significant damage occured.

Severe Tropical Storm Ewiniar (Maring) (12W)
On July 20 at 06:00 UTC, the JTWC, JMA, and PAGASA monitored on a depression northwest of Palau. The JTWC named the depression Tropical Depression 12W while PAGASA named it "Maring". It moved north at first but then moved northwest. On July 22 at 18:00 UTC, 12W stregnthened to a tropical storm accroding to the JTWC. JMA and PAGASA followed suit later doing the same thing the JTWC did. The JMA upgraded it to a tropical storm and was given the next name on the list, Ewiniar, becoming the ninth named storm of the season. PAGASA upgraded "Maring" to a tropical storm. Ewiniar moved northwest and on July 24 at 00:00 UTC, it was upgraded to a severe tropical storm by the JMA and reached its peak intensity on the same time and day. Shortly after reaching peak intensity with 1-minute winds of 60 mph (95 km/h), Ewiniar weakened due to the outflow of Bilis and 12 hours later, the JMA downgraded it to a tropical storm. Later that day, PAGASA issued their final advisory on "Maring" as it left PAR. On July 25 at 18:00 UTC, it made landfall near Taizhou, Zhejiang as a tropical storm with winds of 40 mph (65 km/h) (10-min), 50 mph (85 km/h) (1-min) and a pressure of 993 mbars. On July 26 at 00:00 UTC, the JTWC and JMA downgraded Ewiniar to a tropical depression. It dissipated 12 hours later.

In Palau, its size brought heavy rainfall over the islands, damaging crops and killing a person directly. In the Philippines, despite not making landfall, it enhanced the southwest monsoon bringing heavy rainfall over Southern and Central Luzon and the Visayas. It killed 3 people; 1 direct, 2 indirect. In the Ryukyu Islands, tropical storm force winds occurred in Ishigaki but no deaths occured though heavy rainfall injured some people. In Taiwan, tropical storm force winds brought torrential rainfall over Taipei but no deaths occurred. In China, Zhejiang was the hardest hit with tropical storm force winds bringing flash floods, torrential rainfall, and damage in agriculture and infrastructure. It killed a person indirectly in Zhejiang, China. The system caused $900,000 (2000 USD) in all the areas it affected and damaged.

Severe Tropical Storm Kaemi (13W)
On July 28 at 06:00 UTC, the JTWC and JMA monitored on a tropical depression that formed from a low pressure area near the Marshall Islands. On July 29 at 00:00 UTC, the JTWC and JMA upgraded 13W to a tropical storm. The JMA gave it the next name on the list, Kaemi becoming the tenth named storm of the season, unaware that the correct spelling was Gaemi. It continued northwest and on July 30 at 00:00 UTC, Kaemi reached its peak intensity with 1-minute winds of 65 mph (100 km/h), Shortly afterward, increasing wind shear began to weaken Kaemi and the next day, July 31, Kaemi was downgraded to a tropical storm by the JMA. On August 2 at 00:00 UTC, the JTWC and JMA both downgraded Kaemi to a tropical depression. It dissipated 12 hours later. Its remnants survived but it was later absorbed by Typhoon Prapiroon.

In the Marshall Islands, heavy rainfall brought storm surge across the islands but no deaths occured. Despite this, it only caused minimal damage in the Marshall Islands.

Typhoon Prapiroon (14W)
On August 1 at 06:00 UTC, the JMA and JTWC monitored on a tropical depression that formed from a non-tropical low. The JTWC named it Tropical Depression 14W. 6 hours later, the JMA and JTWC upgraded 14W to a tropical storm. The JMA gave it the next name on the list, Prapiroon, becoming the eleventh named storm of the season. 6 hours later, the JMA upgraded Prapiroon to a severe tropical storm. On August 2 at 00:00 UTC, the JTWC upgraded it to a Category 1 typhoon. The JMA followed suit later, upgrading Prapiroon to a typhoon, becoming the fifth typhoon of the season. 6 hours later, the JTWC upgraded it to a Category 3 typhoon, a sign of rapid intensification. Then, 6 hours later, Prapiroon rapidly strengthened to a Category 4 typhoon, according to the JTWC. The next day, August 3 at 00:00 UTC, Prapiroon reached its peak intensity with 1-minute sustained winds of 145 mph (230 km/h). Then, it underwent an eyewall replacement cycle. The next day, August 4 at 00:00 UTC, it weakened to a Category 3 typhoon according to the JTWC. Then, 12 hours later, Prapiroon weakened to a Category 2 typhoon. Prapiroon then continued westwards intensifying slowly and then on August 6 at 18:00 UTC, the typhoon restrengthened to a Category 3 typhoon as it neared the Ryukyu Islands. On August 8, Prapiroon passed over the Ryukyu Islands. It then entered the South China Sea and shortly afterward, it underwent another eyewall replacement cycle. On August 9 at 00:00 UTC, it weakened to a Category 2 typhoon. On August 10 at 18:00 UTC, Prapiroon made landfall over Zhejiang, China and then weakened to a Category 1 typhoon a few hours later. The next day, August 11 at 00:00 UTC, the JMA downgraded it to a severe tropical storm then 6 hours later, the JTWC downgraded it to a tropical storm. Then 6 hours later, both the JMA and JTWC downgraded it to a tropical storm. Then 6 hours later, the JTWC and JMA downgraded it to a tropical depression. The next day, August 12 at 06:00 UTC, both agencies declared that Prapiroon dissipated.

In the Ogasawara Islands, Prapiroon brought gusty winds, torrential rainfall, and storm surge but no deaths occurred. In the Ryukyu Islands, it also brought gusty winds, torrential rainfall, storm surge, and flying debris, killing 8 people; 6 direct, 2 indirect. In Taiwan, its outer edges brought heavy rainfall which brought flash floods which killed 12 people directly. In China, Zhejiang was the hardest hit with gusty winds, flying debris, storm surge, coastal flooding, and flash floods in some places too, which killed 26 people in Zhejiang, Fujian, Jiangxi, Anhui, and Jiangsu combined. The system caused $200 million (2000 USD) in all the areas it affected and damaged.
