Meteorological History
On April 9, an area of low pressure in the west-central Pacific was designated Invest 92W. On April 12, the JMA designated it a tropical depression, and on April 13, the low was classified as Tropical Depression 02-W by the Joint Typhoon Warning Center. The next day, the JMA named the system Tropical Storm Muifa. Muifa continued on a northwestward course and strengthened into a severe tropical storm on April 15. Muifa then began to weaken as it tracked northwestward, and made landfall in the Northern Philippines on April 16 (Easter Sunday). Muifa then dissipated the next day over unfavorable conditions west of the Philippines.
