Tropical Disturbance South of Guam

The National Weather Service (NWS) Weather Forecast Office Guam has announced of a tropical disturbance (Invest Area 99W) located about 220 miles south-southwest of Guam.  99W will pass south of Guam tonight through Thursday morning heading in a general west direction. 

As of this news release, the disturbance is now the subject of a Tropical Cyclone Formation Alert by the Joint Typhoon Warning Center which means 99W could be upgraded to a tropical depression within the next 24 hours.

NWS Special Weather Statement

The National Weather Service (NWS) Weather Forecast Office Guam is tracking a circulation south of Guam that is expected to strengthen the Monsoon over Micronesia.
A large tropical disturbance located between Yap and Chuuk is expected to gradually develop within the next few days. It is expected to pass through Yap and Guam around Thursday.

Although there is no significant development at this time, we can expect heavy showers with gusts of southwest to south monsoon winds, and choppy seas to persist for the next few days.
