CORRECTED HEADLINE.

...HEAVY SHOWERS AND THUNDERSTORMS ACROSS YAP STATE AND PALAU
THROUGH MIDWEEK...
...WEST WINDS TO BE GUSTY AT TIMES...

An active monsoon pattern has developed across Western Micronesia
with recent satellite imagery showing broad areas of heavy showers
and thunderstorms. Midday satellite-derived surface wind data depicts
15 to 20 mph west winds across Western Yap State and Palau.

Computer models point to a continuation of these conditions into
midweek with periods of heavy showers moving across the islands,
occasionally bringing increased winds, gusts and choppy seas. Both
Yap and Palau are in the monsoon inflow of JTWC`s Invest 91W, (that
is located near 11N144E between Yap and Guam). As 91W continues to
organize showers are expected to remain widespread and heavy at
times. Model guidance suggest up to 1 to 2 inches of rain a day
through Wednesday, then tapering down to about 0.5 inch for the
following few days.

Residents should continue to monitor forecasts and listen for any
marine advisories that may be issued over the next several days. Be
aware of the latest weather conditions and trends before traveling
between islands. Stay up-to-date with all the latest forecasts at
weather.gov/gum and by following the latest information from your
local Weather Service Office.
