...HEAVY RAINFALL POSSIBLE THIS WEEK...
...FLOOD WATCH IN EFFECT FROM THIS EVENING THROUGH THURSDAY
AFTERNOON...

A developing tropical disturbance, known as JTWC`s Invest 95W, is
currently located northwest of Weno, Chuuk. Forecast guidance
continues to show a gradual organization as it heads towards the
Marianas over the next few days. Model consensus indicates the
possibility of locally heavy rainfall of 4 to 8 inches across the
Marianas. Such rainfall could lead to localized flooding and the
potential for flash flooding.

Models have begun to converge on a track across the southern
Marianas. Heavy rainfall possible for Guam and the Marianas with
the passage of Invest 95W, and a robust south to southwest flow
sets up in its wake by the latter half of the workweek.

Localized flooding will be possible in low-lying and poor drainage
areas, while flash flooding could also be possible in areas of
heaviest rainfall.

TIMING: Tonight through Thursday.

RAINFALL: 4 to 8 inches of rainfall with locally higher amounts
likely.

Monitor local weather forecasts and conditions closely the next
few days. Outdoor plans and events should have an alternate plan
in place should heavy weather occur. When thunder roars, get indoors.
If you can hear thunder, you are at risk of a lightning strike. Plan
ahead and stay informed  with the latest news from your local
emergency management offices and the National Weather Service
(weather.gov/gum).
