CORRECTED TYPOS AND UPDATED DISCUSSION.
...A DEVELOPING MONSOON PATTERN IS EXPECTED TO BRING HEAVY
DOWNPOURS...GUSTY WINDS...AND CHOPPY SEAS THE NEXT SEVERAL DAYS...
A DEVELOPING MONSOON PATTERN IS PRODUCING FRESH WEST-SOUTHWESTERLIES
AND A SURGE OF NUMEROUS TO WIDESPREAD LOCALLY HEAVY SHOWERS AND
THUNDERSTORMS, ACCOMPANIED BY STRONG TO NEAR-GALE GUSTS. THERE IS
SOME INDICATION THAT A MONSOON DISTURBANCE MAY GRADUALLY FORM TO THE
NORTH-NORTHEAST, WHICH COULD LEAD TO AN INTENSIFIED MONSOON SURGE
ACROSS PALAU AND YAP. MODEL GUIDANCE SUGGESTS 3 TO 5 INCHES THROUGH
THE MIDDLE OF THE WEEK, AND AN ADDITIONAL 2 TO 4 INCHES THROUGH THE
LATTER HALF OF THE WEEK, TOTALING 6 TO 9 INCHES BY THE WEEKEND. IF
THESE SHOWERS DEVELOP AS EXPECTED, SOILS WILL BECOME SATURATED ENOUGH
TO POSE A RISK FOR MUDSLIDES TOWARD THE END OF THE WEEK. AT THIS
TIME, THE RISK REMAINS LOW. AS THE MONSOON PATTERN CONTINUES TO
DEVELOP, WINDS AND SEAS WILL INCREASE, BUT ARE EXPECTED TO REMAIN
BELOW CONDITIONS HAZARDOUS TO SMALL CRAFT. AS A TROPICAL DISTURBANCE
EMBEDDED WITHIN THE MONSOON TROUGH ATTEMPTS TO CONSOLIDATE, IT WILL
MOVE NORTH AND CARRY THE BULK OF THE CONVECTIVE MONSOON WITH IT,
EASING THE SHOWERS AND WINDS NEAR PALAU AND YAP AS EARLY AS SATURDAY.
FOR MORE INFORMATION, RESIDENTS AND MARINERS SHOULD MONITOR THE
LATEST FORECASTS FOR THE REGION AT WEATHER.GOV/GUM/PUBLICFORECASTS
AND ANY INFORMATION SHARED BY WSO PALAU AND WSO YAP FOR THEIR LOCAL
REGIONS.
