...DIMINISHING THREAT OF DEVELOPING TROPICAL CYCLONE TO AFFECT
MARIANAS...
THE DISORGANIZED TROPICAL DISTURBANCE, INVEST 97W, IS CENTERED WELL
WEST OF SAIPAN NEAR 16N140E. RECENT RADAR AND SATELLITE IMAGERY SHOWS
A MUCH QUIETER PATTERN ACROSS THE MARIANAS WITH HEAVY SHOWERS HAVING
PUSHED OFF WELL TO THE WEST OF THE ISLANDS AFTER DUMPING 2 TO 5
INCHES OF RAIN OVER MUCH OF THE REGION THE PAST 36 HOURS.
WHILE LATEST MODEL GUIDANCE STILL FAVORS GRADUAL DEVELOPMENT OF 97W
IN THE COMING DAYS, SUCH TRENDS WILL BE SLOW AND INCREASINGLY FURTHER
AWAY FROM THE MARIANAS. THUS FAR, THE DOMINANT CONCERN HAS BEEN THE
RAINFALL THREAT FOR THE NEXT SEVERAL DAYS. THE DEPARTURE OF 97W FROM
THE MARIANAS DOES LESSEN THAT CONCERN, THOUGH THE MARIANAS SHOULD
STILL ANTICIPATE HEAVIER SHOWERS AND THUNDERSTORMS MOVING OVER THE
ISLANDS FROM TIME TO TIME.
CONCERNING THE THREAT FOR WIND HAZARDS, THAT CONCERN IS MUCH REDUCED
WITH 97W PULLING AWAY FROM THE LOCAL AREA. HOWEVER, FOLKS PLANNING
OUTDOOR ACTIVITIES OR OUT ON THE WATERS SHOULD KEEP UP-TO-DATE WITH
CURRENT WEATHER CONDITIONS AND FORECASTS.
THE NWS WILL CONTINUE MONITORING FOR THE POTENTIAL OF A WET AND
GUSTY SOUTHWEST MONSOON PATTERN THAT COULD DEVELOP OVER THE ISLANDS
NEXT WEEK.
THIS WILL BE THE FINAL SPECIAL WEATHER STATEMENT ISSUED REGARDING
INVEST 97W. KEEP UP-TO-DATE WITH THE LATEST FORECASTS AND DISCUSSIONS
