NWS expects several inches of rainfall this week.

Guam – The National Weather Service says Guam is expected to see several inches of rainfall this week due to a upper-level trough and a weak tropical disturbance.

 

In its Area Forecast Discussion from this afternoon, NWS writes, “As the upper-level trough moves a bit farther west of the Marianas.. upper-level flow will become more favorable for the development of showers and thunderstorms over the Marianas tonight and Wednesday.”

 

On top of the trough bringing rain, NWS also points out a weak tropical disturbance as one of the rain makers as it writes, “On addition.. models show the tropical disturbance south-southwest of Guam will slowly move north-northwest to the west of the Marinas by Thursday.”

 

“Model agreement has been good as well as run-to-run consistency in bringing several inches of rainfall through Friday for the Marianas,” the Weather Service concludes.
