..DEVELOPING DISTURBANCE TO BRING HEAVY DOWNPOURS
GUSTY
WINDS...AND CHOPPY SEAS THE NEXT SEVERAL DAYS...
A TROPICAL DISTURBANCE, KNOWN AS JTWC'S INVEST 90W, IS CENTERED NEAR
9N154E NORTHEAST OF WENO, CHUUK. THIS SYSTEM IS SLOWLY CONSOLIDATING
AS IT CONTINUES TO MOVE TO THE NORTHWEST, LIKELY TO MOVE NORTH OF
CHUUK AS STRONGER SOUTHWESTERLIES DEVELOP OVERHEAD. JTWC RATES THIS
FEATURE AS A MEDIUM MEANING TROPICAL CYCLONE DEVELOPMENT IS LIKELY,
BUT IS EXPECTED TO OCCUR BEYOND 24 HOURS. FOR THIS REASON, THE
CHANCE OF THIS SYSTEM DEVELOPING INTO A SIGNIFICANT TROPICAL CYCLONE
DURING ITS CLOSEST APPROACH NEAR CHUUK REMAINS LOW. HOWEVER, THE
PROXIMITY OF THIS SYSTEM IS EXPECTED TO BRING HEAVIER SHOWERS, FRESH
WINDS AND STRONG TO NEAR-GALE GUSTS OVERNIGHT. DUE TO THE LOOSE
ORGANIZATION OF 90W, VARIABILITY IN AREAS OF CONVECTIVE DEVELOPMENT
MAY PRODUCE PERIODS OF LITTLE TO NO WEATHER FOLLOWED BY SPORADIC
HEAVY SHOWERS AND THUNDERSTORMS. IN ADDITION, HIGH UNCERTAINTY
REMAINS REGARDING RAINFALL AMOUNTS, BUT MODEL TRENDS INDICATE 3 TO 5
INCHES AT WENO, CHUUK THE NEXT 48 HOURS, TO THEN POSSIBLY BE HIGHER
AT OUTER ISLANDS SUCH AS FANANU. BY THE WEEKEND, CONDITIONS ARE
EXPECTED TO IMPROVE CONSIDERABLY AT WENO AS 90W CONTINUES TO MOVE
AWAY FROM THE AREA TO THE WEST-NORTHWEST, WHERE SHOWERS AND WINDS MAY
BECOME MORE ACROSS EASTERN YAP STATE.
COMBINED SEAS ARE EXPECTED TO REMAIN HAZARDOUS CRITERIA FOR SMALL
CRAFT OPERATIONS THROUGH AT LEAST TONIGHT. THEN, A SHORT DIP BLOW
CRITERIA MAY TAKE PLACE AS 90W MOVES FURTHER NORTHWEST, HOWEVER,
SEAS WILL LIKELY TO BECOME HAZARDOUS DURING THE WEEKEND ACROSS CHUUK
STATE AND EASTERN YAP STATE AS MORE SIGNIFICANT NORTHERLY SWELLS AND
MUCH HIGHER LOCAL WIND WAVES DEVELOP. SEAS WILL BECOME MORE CHOPPY
OVER THE NEXT SEVERAL DAYS, SO MARINERS MUST CONTINUE TO MONITOR THE
LATEST MARINE FORECASTS BEFORE VENTURING OUT TO THE OUTER ISLANDS.
RESIDENTS AND MARINERS SHOULD MONITOR THE LATEST FORECASTS FOR THE
REGION AT WEATHER.GOV/GUM/PUBLICFORECASTS AND ANY INFORMATION SHARED
BY WSO CHUUK AND WSO YAP FOR THEIR LOCAL REGIONS.
