Pacific hurricane season 2013 , 2014 , 2015, 2016 , 2017 | |
The 2015 Pacific hurricane season officially began on May 15 in the Eastern Pacific and June 1 in the Central Pacific. It ends on November 30th. Most tropical storms usually form during this period, as the conditions for hurricanes to form are good , the ocean is warm enough, the humidity is high and there is hardly any wind shear , but a tropical storm could form at any time. All storms north of the equator and east of 180 ° W are included. The storms that form west of 180 ° W are called typhoons and are part of the 2015 Pacific typhoon season .
The season started with the formation of the tropical storm "Andres" on May 28, 2015. The tropical storm was upgraded to a hurricane within a few days and reached wind speeds of up to 225 km / h at its peak, which is category 4 according to Saffir-Simpson - Equals hurricane wind scale . Just four days after Andres, tropical storm "Blanca" occurred and also became a Category 4 hurricane. The second Category 4 hurricane has never been registered so early in the year since regular, widespread records began in 1971.

On May 28, 2015 at 09:00 UTC, the system was upgraded to Tropical Depression One and just six hours later to Tropical Storm Andres. One day later, Andres achieved hurricane status and on May 30th, category 2 on the five-part hurricane scale. A day later, Andres began a rapid intensification and reached major hurricane strength (category 3+). On the night of June 1st, Andres peaked with category 4 and sustained wind speeds of up to 240 km / h. Only two days later Andre had weakened again to a tropical storm and on June 4th almost completely dissolved.
Effects
Hurricane Andres did not threaten land at any time, but after its dissolution the remnants of the storm system caused heavy rains in Arizona, which caused flooding. People were not harmed.

Just one day later, after a rapid intensification, Blanca already reached category 4 and on the evening of June 3rd its peak with sustained wind speeds of up to 220 km / h and an air pressure of 943hPa. In the next few days there was a so-called "new eyewall formation" in the area of the core of Blanca. The hurricane temporarily weakened to Category 1. On June 6th, Blanca was upgraded to category 4 again, but from there the tropical storm moved into cooler waters and weakened enormously again. On June 7th, Blanca was just a tropical storm. One day later, on June 8th at 12:00 UTC, Blanca hit the Baja California peninsula, near Puerto Cortés. On June 9th, Blanca disbanded.
