Guam and the Northern Marianas preparing for Typhoon Chan-hom

July 2, 2015

Typhoon Chan-hom formed in the western North Pacific on June 30, and is expected to affect Guam and the Northern Marianas (collectively known as The Marianas) with strong winds and heavy rainfall within the next 48 hours. According to the latest Public Advisory from the National Weather Service Forecast Office in Tiyan, Guam, Typhoon Chan-hom is expected to pass through The Marianas early Sunday morning (local time).

A Typhoon Watch remains in effect for Guam, Rota, Tinian, and Saipan, and residents are encouraged to begin preparing for severe weather conditions. In addition to typhoon force winds, dangerous surf and storm surge (up to 22 feet) are possible by Saturday evening. Heavy rainfall is also expected to increase the risk of flash flooding through Monday.

Earlier this year, Typhoon Dolphin impacted The Marianas, passing between Guam and Rota.

Pacific Disaster Center is closely monitoring Typhoon Chan-hom as it approaches The Marianas, and will continue to provide decision support and situational awareness products for the duration of the event.
