2018 Danula Planetwide Cyclone Season

The basin
While the season is planetwide, all activity occurs in one ocean.

The seasons use the Lucarius Wind Scale, with categories 1 - 9, as well as tropical depression, tropical storm, and severe tropical storm.

The seasons officially run from June 1st to December 31st. However the most active season before the 2018 season ran from June 3rd, 2017 to June 2nd, 2018, due to the seasons technically being year round from June 1st to June 1st next year due to a complex setup of the Danulean traditional new year occuring on June 1st and the official boundaries of the season.

Lucarius Wind Scale (LWS)
Tropical Depression: Under 39 mph(< 33.9 kn)

Tropical Storm: 40-54 mph(34.8-46.9 kn)

Severe Tropical Storm: 55-69 mph(47.8-60.0 kn)

C1 Hurricane: 70-84 mph(60.8-73.0 kn)

C9 Major Hurricane: Over 200 mph(> 173.8 kn)

The season
The 2018 Danula Planetwide Cyclone Season is an ongoing event in tropical cyclone formation. It the most active and destructive season in the basin's history, and is one of the deadliest.

The season's official bounds are June 1 to December 31, however storms can form year round, and storms forming between January 1 to June 1 are considered part of the previous season.

The season had an average start, with June having 2 named storms, with negligible effects. July was an above average month, where 7 storms formed, the strongest of them Daniel, a relatively rare July major, and the most destructive Harvey, which was a devastating flooding disaster in Floodston. An additional depression was found in post season analysis in the month of July.

August started early with Jose, which became the season's first Category 5, swiftly followed by Katherine, which was a devastating Category 5 at 2 of its landfalls. Lenny was, meanwhile, a meandering storm existing in the mid part of August, not reaching any significant intensities. Margharet was an even less relevant storm, only having gale-force winds for 2 days.

Nathan became the fourth major of the season as it moved through the northern Main Development Region, and became a Category 4, but ultimately did not affect land. It did, however, create a lengthy period of constant tropical cyclone activity that only ended on the 7th of October due to Barry becoming extratropical for a bit, and a 12 hurricane in a row streak. After Nathan followed Opal, a very long tracked and long lasting storm that was destructive in the region of Hotston, but is more notable for peaking as a Category 5 at the same time as Philippe peaked as a Category 5. Philippe, on the other hand, was an extremely intense system but it did not last very long at all. However it did manage to do devastating amounts of damage to areas affected by Katherine earlier in August, by making another 2 Category 5 landfalls. Rita formed in the late part of August, and became a hurricane as well as the most intense storm in the Subtropical MDR until later, but it did not manage to make any tropical landfalls.

September started with Stan, which was the longest lasting storm of the season until Barry, and is by far the most intense and strongest, as well as the second costliest. It started as a wave, and made some Category 4 landfalls before heading into the Gulf of Floodston, where it exploded from 70 mph to 210 mph in 24 hours, and peaked at a record breaking 210 mph, and an extreme 873 mbar. Then it struck Floodston with unprecedented intensity, causing large amounts of devastation. It then stalled over land dropping rain, until it eventually dissipated, and was absorbed by Tammy. Tammy, meanwhile, was an MDR major that later weakened below storm status and reintensified, made landfall and absorbed Stan's remnants while over land. Vince was a small hurricane force system that hit land at its peak intensity in mid September. Whitney was yet another MDR major, which wasn't very long lasting or intense.

Acorn was the first storm in the basin to be named using an auxiliary list, and caused high damages in Hotston, while striking it with a large radius. Barry was a storm with a relatively long history, it first formed in September and was relatively weak until it started looping around in the MDR, when it became a medium end Cat 3. It peaked as a Category 5 and later made a 150 mph landfall in Hotston city, causing unprecedented damage, and becoming the costliest storm of the season. Chandra was a surprise storm that formed out of nothing and yet reached very destructive intensities, becoming the second most powerful storm of the season.

Douglas became the strongest subtropical MDR storm of the season, peaking as a minimal Category 2, and thus yet another major. However, due to small size it did not cause significant effects. Evelyn was another Subtropical MDR storm, but that time it failed to reach anything significant - it only was a storm for 6 hours. Fabio formed in the very western MDR, and made a devastating and deadly Category 5 landfall in an impoverished area, causing over 2000 fatalities.

On the 30th of October, Potential Tropical Cyclone Twenty Nine became the first PTC to be designated in the basin. It finally became a tropical system at 06:00 November 1, and a Tropical Storm (debatably) at 18:00 November 1, and was named Gloria. It quickly lost circulation and became a remnant.

On the 6th of November, PTC 30 was designated. At 18:00 November 7 it became TS Harmony. It is currently moving through the eastern MDR and rapidly intensified, peaking on the 9th of November, and made severe effects on land as a major landfalling cyclone. Meanwhile, PTC 31 formed on the 7th of November and is currently moving through the western MDR. It became a tropical depression on the 9th of November, and became a storm the next day, getting the name Isa.

On the 24th of November, after a 5 day period as an Area of Interest, PTC 32 was designated. It became a storm on the 25th, and was named Jazlyn. It became a hurricane on the 26th, and a major on the 27th. It peaked on the 1st of December as it made landfall in Andreaston. It made landfall in Andreaston with 195 mph winds and a pressure of 886 mbar, the most intense December landfall on record, and was a significant storm for Andreaston, which was crippled, with damages reaching over 300 billion and a death toll of over 3000. Meanwhile, PTC 33 formed on the 7th. It became a depression on the 8th, and a storm on the 9th, getting the name Korra. It peaked as a major hurricane on December 11th, with no major land impacts.

On December 24th, PTC 34 and 35 formed from the same extratropical system, with PTC 34 being the main core and 35 being an associated low. PTC 34 became Subtropical Storm Layten on the 25th of December. On the 26th PTC 35 became Tropical Storm Michael. On the 27th they both became hurricanes and were in a fujiwhara interaction. They both reached major hurricane status on the 29th, and Layten dissipated on January 5th while Michael dissipated on the 31st, both making major strength landfalls.

On the 19th of January 2019, after a long break in activity, PTC 36 formed. After one day it developed into Subtropical Storm Nacho. It peaked on January 22nd as a Severe Tropical Storm. It then became extratropical 12 hours later.

On January 30th, PTC 37 formed. It became a Subtropical Storm and got the name Olivia on February 1st. On the 2nd it became a Severe Subtropical Storm. On the 3rd, it became a hurricane and peaked, as well as making landfall at peak intensity. Later, it emerged over water and reintensified to hurricane status again on the 7th, and peaked as a major on the 8th. It then weakened until it made landfall, and eventually became an extratropical system on the 10th.

On February 25th, Tropical Depression Thirty Eight formed. On the 26th it became a storm and was named Pauline. On the 27th it became a hurricane. On the 28th it became a major hurricane. It initially peaked on March 1st as a Category 6 hurricane, after that starting weakening due to an EWRC. After reaching lowest intensity between peaks on March 2nd, it reintensified again and peaked for the second time on March 3rd, on its main peak, becoming the most intense storm in March, beating the previous record holder by 2 mbar, at 907 mbar. After its landfall at peak intensity, it weakened back to a hurricane on March 4th. On March 6th it weakened to a severe tropical storm. It dissipated on March 7th. Complete destruction was reported in affected islands, due to 160 mph sustained winds and 190 mph gusts present in the storm at the time of landfall.

There is currently one active system, Category 3 Major Hurricane Rebecca.

Season summary
Activity for the season began just later than usual, with Anguilla forming in late June, however it quickly became one of more powerful June systems recorded, becoming a rare June hurricane. SD 02 was a rare June subtropical depression, but was very short lived. Barthelemy and Caroline followed, but were both weak, short lived storms.

July started with Caroline forming very early in the month. It was irrelevant to the activity overall. However, Daniel later became a rare July major hurricane, and was followed by two another hurricanes, both peaking as Category 2s. Gertrude was an odd storm that dissipated and regenerated, having a very short lived severe TS peak. Harvey was the next in line, and ended up as a devastating rainmaker storm for Floodston. An additional depression was found in early July by reanalysis. It was operationally deisgnated as an Invest, but was found to have been a fully tropical system.

August started very early, with Irene peaking very early in the month. Jose then became a Category 6 early in the month, followed by another strong system, Katherine, becoming the most powerful storm of the season yet as a Category 7, and making a catastrophic landfall as a Category 7, and another as a Category 6. Meanwhile, two weak storms formed at the time, Lenny and Margharet, Margharet being short lived while Lenny was relatively long lived.

In mid August, Nathan started a chain of hurricanes and constant activity for just under two months. Opal formed later, and was the longest lived storm of the season yet, and coexisted with Philippe and they both eventually peaked on the same day as Category 7 systems. Philippe later made two catastrophic landfalls, one as a Category 7 and one as a Category 6. Rita was a weak hurricane in the subtropical MDR, but was the most powerful storm in the region in the season yet.

September started weak, with Stan forming early in the month. However, in mid September Stan rapidly intensified and became the most powerful storm of the season, also breaking the record for the highest windspeeds recorded. It then made a devastating landfall, the most powerful in the season at the time, and reflooded Floodston city after Harvey. While that was going on, Tammy peaked as a major in early September and eventually absorbed Stan before dissipating overland, Vince peaked as a weak, short lived and small hurricane, Whitney had a short lived major peak before dissipating over sea, Acorn formed and would eventually be one of three major storms for Hotston city making landfall as a weak major, and Barry started its month long track which would eventually bring it to the longest lived storm of the season, a Category 6 peak and yet another Hotston landfall, this time as a weak Category 6. Chandra formed late in the month, and rapidly intensified, becoming the second most powerful storm of the season at landfall in October, and having the most powerful landfall of the season.

October started powerful with Chandra's landfall and Douglas forming, becoming a major and the strongest storm in the subtropical MDR of the season. Evelyn was another subtropical MDR storm in mid October, but was weak and short lived. Fabio was a relatively short lived Category 6 forming in mid October, but was devastating to an impoverished area, and peaked at the same time that Barry peaked, both as Category 6 storms.

November started with Gloria debateably becoming a weak tropical storm early in the month. A few days later, Harmony formed and became a strong system, becoming the third and last storm to strike Hotston this season as a major, while Isa was a storm peaking in the middle of the ocean and ultimately had no effects. Jazlyn was the last storm of November, and became a very powerful storm.

December started very powerful yet again, with Jazlyn peaking at landfall as the third most powerful storm of the season and the second strongest landfall of the season, on December 1st. It had a long track, and dissipated before regenerating for a short time as a weak storm and finally dissipating in mid December. Korra was another major hurricane, and had irrelevant land effects in mid December.

In late December Layten and Michael's precursors formed from the same extratropical system, Layten forming a day later and Michael another day later, with both eventually entering a fujiwhara interaction as minimal hurricanes, Layten later peaking as a Category 6 and even later making a 110 mph landfall in January, while Michael peaked as a weak major at landfall.

In mid January, PTC 36 formed and was expected to become subtropical within 1 day of declaration. Surely enough, on January 20th it did. It continued intensifying, becoming tropical on January 21st, and eventually peaking on the 22nd as a severe tropical storm, before weakening and turning extratropical on the 23rd.

In late January, PTC 37 formed and became a subtropical storm on February 1st and was named Olivia. It intensified over the next days, eventually initially peaking on February 3rd as a hurricane and making landfall at peak intensity. It then moved over land for a bit, before reemerging into the ocean and starting reintensification again, having its main major hurricane peak on February 8th, then weakening and transitioning into an extratropical cyclone on the 10th.

On February 25th, TD 38 formed. On the 26th, it became a named storm and was named Pauline, and intensified to initially peak as a Category 6 hurricane on March 1st. It weakened due to an EWRC, but reintensified to a Category 6 on March 3rd, and peaked again, this time as the most intense March hurricane, at 907 mbar, breaking the previous record holder by 2 mbar. It made landfall at that intensity, and weakened to below major status by the next day. It slowly moved southeast as it weakened, and lost its tropical system status on March 7th.

Storm names
These are the names that will be used to name tropical cyclones in the 2018 season. This list was last used in 2016 and will be used for the next time in 2020, with the exception of the names retired due to their impacts. In addition, the DWFC has chosen an auxiliary list to use if the normal list is exhausted. Auxiliary lists are rotated on a two year basis, which means that this list will be used for the next time in 2020. 2018 was the first usage of an auxiliary list.

Retirement
So far, Daniel, Harvey, Jose, Katherine, Philippe, Opal, Stan, Acorn, Barry, Chandra, Fabio, Harmony, Jazlyn, Layten, Michael, Olivia and Pauline were requested for retirement. Retired names, if any, will be announced on June 1st of 2019, along with their replacement names.
