Typhoon Genevieve(2020)

Typhoon Genevieve, also known as Typhoon Siony in the Philippines was an abnormally long lived tropical cyclone especially for the time of year in which Genevieve existed. Existing as the seventh named storm of the 2020 Pacific Hurricane Season, Genevieve formed on October 14 as a Tropical Depression from an Area of Disturbed Weather. Despite a quick formation, Genevieve spent the vast majority of it's life in the Eastern Pacific at Tropical Depression status before temporarily strengthening to a Tropical Storm shortly before crossing into the Central Pacific. Due to an uptick in wind shear, Genevieve weakened back to Tropical Depression status on October 18 well to the south of Hawaii. Subsequently, the cyclone strengthened once again back to Tropical Storm status before accelerating further on a generally Westward motion. Genevieve would cross the International Date Line, therefore now being tracked by the Japan Meteorological Agency. This became the first time a cyclone would exist in all three Pacific Ocean areas since another Hurricane named Genevieve did 6 years prior.

Shortly following, Genevieve would reach Typhoon status according to the JMA. Continuing a westward motion with favorable conditions; Genevieve continued gradual intensification throughout the next several days before reaching Major equivalent intensity of 115 mph(1-minute sustained). In the days following, a series of three Eyewall replacement cycles would hinder significant intensification jumps, as it waned between Categories 2 and 3 on the Saffir-Simpson Scale, passing through the Northern Mariana Islands and Guam while doing so. On October 20, PAGASA would give the name Siony to the Typhoon as it entered the Philippine Sea Genevieve would begin to intensify gradually again before reaching a peak intensity of 120 mph, 920 mbar according to the JMA, with the Joint Typhoon Warning Center confirming 1-minute sustained winds of 145 mph. The cyclone would begin a Northward motion shortly thereafter, heading towards the Ryuku Islands of Japan. However, an Extratropical transition would take place and the cyclone would be classified as Non-Tropical on November 2. In the 3 days following, the now Extratropical cyclone would go straight through Amani Oshima before switching to a Northeastern direction and hitting Japan. On November 5, Genevieve met it's demise.
