Storms

Tropical Storm Anna

Anna originated from a vigorous tropical wave that moved west along the ITCZ during the days of March 16 and 17. On March 18 an approaching cold front caused the wave to congeal into a tropical low pressure system while about to the east of Davao. The system rapidly organized into a tropical storm and continued west. Anna made landfall on

Super Typhoon Rosalind

The origins of Rosalind can be traced to a tropical storm that intensified into a category 2 on October 6. Rosalind continued to rapidly intensify from 964 to 918 mbar, reaching its peak intensity. After Rosalind reached its peak intensity, slight wind shear caused Rosalind to weaken on a category 2 on October 10. It intensified into a category 3 before it moved slowly. It weakened to a category 1 and tropical storm. Rosalind dissipated on October 14. Rosalind was the first super typhoon ever recorded in the Pacific Ocean.

Tropical Storm Irene

Tropical Storm Irene formed on November 30 between the Philippine Islands. It strengthened to a tropical storm with 50 mph winds before it made landfall on one of the islands. It curved northeast and weakened to a tropical depression. But after exiting land, it restrengthened to a moderate tropical storm. But shortly thereafter, it became extratropical on December 3. The Japan Meteorological Agency analyzed it as a tropical depression, though it was actually a moderate tropical storm.
