2014-15 Doreen typhoon season

Hypertyphoon Abby
On November 2, Tropical Storm Abby formed. It explosively became a Hypertyphoon within 18 hours. WCETCC was really surprised beating Kiera of 2013-14.

Hypertyphoon Bret
On November 18, Tropical Depression Two-D formed. It explosively became a tropical storm then a typhoon and finally a Category 12 super typhoon within 4 days. 3 days later it became a 500 mph hypertyphoon while still strengthening it peaked as a 550 mph hypertyphoon with a minimum central pressure of 593 millibars on November 26. Due to its close proximity to Abby it started to weaken until Abby moved faster and moved away from it. It was left as a minimum 500 mph hypertyphoon spinning still in the basin. It did a fujiwhara effect with Category 7 super typhoon Crystallia on December 24, it ended up absorbing Crystallia after it weakened to a Category 3 typhoon. The merger made Bret reach a secondary peak intensity of 525 mph and a minimum pressure of 601 millibars. It maintained this intensity until January 28 when a extremely powerful extratropical cyclone was racing towards it, it was of hypertyphoon intensity. The powerful system starting shearing apart Bret. Within 24 hours it was a minimum typhoon being absorbed into the frontal system. By January 31 it was completely absorbed into the extremely powerful extratropical cyclone.

Typhoon Crystallia
It formed from a tropical disturbance on December 19, it immediately strengthened into a tropical storm. In 3 days it intensified from a 60 mph severe tropical storm to a Category 8 super typhoon. However it weakened to a category 7 after Bret passed close to it, it was imparting heavy wind shear on it. By December 24 it rapidly weakened from a category 6 to a 5, 4, and then a 3 and got absorbed into the hypertyphoon.
