...HEAVY SHOWERS AND THUNDERSTORMS ACROSS YAP STATE 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 Yap State with a few areas of stronger
gusts north of Faraulep.

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. By
midweek, models indicate the potential for a circulation to slowly
organize as it passes between Yap and Guam into the Philippine Sea.
As this happens, westerly winds and gusts will increase with showers
and thunderstorms. While these conditions will generally be felt
across Yap State, portions of the Republic of Palau could see heavy
showers and thunderstorms dropping south early in the week.

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.
