STORM HISTORY
A powerful March passage
Maysak developed east of Pohnpei in late March and became a named storm on March 27. It moved west-northwestward through the Federated States of Micronesia, strengthening into a typhoon. Rapid intensification brought sustained winds to an archived maximum of 150 knots on March 31.
Chuuk and Yap suffered severe damage. The saved account reports four deaths in the Federated States of Micronesia and losses of approximately US$8.5 million in 2015 dollars. The Red Cross estimated that about 5,000 people urgently needed food, water and shelter after the storm.
A much weaker arrival in the Philippines
Maysak weakened after its brief Category 5 phase and continued toward Luzon. It reached the island on April 5 with winds far below its offshore maximum, and damage in the Philippines was limited. The remaining circulation continued to weaken, with the archived track ending on April 7.

METHODOLOGY
Data sources and limitations
The map and summary are generated from NOAA's IBTrACS v04r01 archive. Wind and category use US-agency records; minimum pressure is calculated during the tropical stage, with the archive's pressure source retained. Category 5 refers to the Saffir–Simpson one-minute wind scale; local agencies may use different classifications. Coastlines use Natural Earth's 1:10m land data.
Track distance adds great-circle distances between consecutive observations, excluding gaps over 12 hours. This track has no gaps over 12 hours. The line shows the storm's center, not its size, rainfall or flood extent. Converted wind speeds are rounded to the nearest whole unit.
