The National Weather Service (NWS) in Tiyan, Guam has issued a typhoon watch and Tropical Storm warning on Nov. 20. A Typhoon Watch remains in effect for Faraulep in Yap State and for Puluwat in Chuuk State. A Tropical Storm Warning is in effect for Chuuk Lagoon, Lukunor, Losap, Fananu, Ulul, and Puluwat in Chuuk State and for Satawal in Yap State.

Tropical Depression Man-yi formed on Nov. 20 and NASA-NOAA’s Suomi NPP satellite passed overhead. The Visible Infrared Imaging Radiometer Suite (VIIRS) instrument aboard NASA-NOAA’s Suomi NPP satellite provided a visible image of the storm. Man-yi is a large area of low pressure. The image showed powerful thunderstorms around the center of circulation and a large, thick band of thunderstorms feeding into the center from the west were bringing gusty winds and rainfall to the Federated States of Micronesia.

On Nov. 20 at 7 a.m. EST (1200 UTC/10 p.m. CHST local time), the center of Tropical Depression Man-yi was located near Latitude 4.8 degrees north and longitude 154.2 degrees east. Man-yi is moving west at 10 mph. It is expected to make a slight turn toward the west-northwest with an increase in forward speed through Thursday. NWS in Guam said that maximum sustained winds remain at 30 mph. Man-yi is forecast to intensify through Friday possibly becoming a tropical storm Wednesday.
