...INCLEMENT WEATHER AND ROUGH SEAS ACROSS WESTERN YAP STATE AND
PALAU...

A BROAD MONSOONAL DISTURBANCE IS CENTERED SOUTHEAST OF YAP NEAR
5N145E THIS MORNING. IT IS ABOUT 570 MILES SOUTHEAST OF YAP AND 740
MILES EAST-SOUTHEAST OF KOROR. ASCAT SATELLITE IMAGERY REVEALS FRESH
TO STRONG MONSOONAL NORTHWEST TO WEST WINDS NEAR THE DISTURBANCE
SOUTHEAST OF KOROR AND YAP. INFRARED SATELLITE LOOPS SHOWS HEAVY
SHOWERS AND THUNDERSTORMS SOUTH OF KOROR AND JUST EAST OF YAP.

THIS DISTURBANCE IS EXPECTED TO MOVE SLOWLY WEST-NORTHWEST OVER THE
NEXT FEW DAYS AND SHOULD PASS BETWEEN KOROR AND YAP TUESDAY AND
WEDNESDAY. ANY FURTHER DEVELOPMENT SHOULD BE SLOW BUT IT WILL BRING
RAINY AND WINDY CONDITIONS FOR WESTERN YAP STATE AND THE REPUBLIC
OF PALAU THROUGH MIDWEEK. PERIODS OF HEAVY RAIN ARE LIKELY ACROSS
WESTERN YAP STATE TONIGHT AND MONDAY...AND POSSIBLY FOR PALAU MONDAY
NIGHT AND TUESDAY. THIS WILL INCREASE THE CHANCE OF MUDSLIDES.

BUILDING MONSOONAL SWELL AND WIND WAVES WILL CAUSE SEAS AND SURF TO
RISE OVER THE NEXT FEW DAYS. THIS COULD LEAD TO HAZARDOUS CONDITIONS
FOR SMALL CRAFT OPERATION AND HAZARDOUS SURF BY TUESDAY.

IF YOU ARE OPERATING SMALL BOATS OR PLANNING INTER-ISLAND TRAVEL OR
OUTDOOR ACTIVITY...BE AWARE OF THE CURRENT MARINE AND WEATHER
CONDITIONS. STAY INFORMED ON THE LATEST FORECASTS AND ADVISORIES
