...GUSTY WINDS AND HEAVY RAINFALL EXPECTED THE NEXT SEVERAL DAYS
DURING PASSAGE OF TROPICAL DEPRESSION NURI ALONG WESTERN WATERS...
NEWLY FORMED TROPICAL DEPRESSION NURI (03W) IS CURRENTLY NORTHWEST
OF YAP, WHICH IS THEN EXPECTED TO GRAZE THE MARIANAS ALONG THE
NORTHWESTERN COASTAL WATERS OVER THE NEXT FEW DAYS AS IT HEADS
NORTHEAST AND INTERACTS WITH REMNANTS OF AN OLD FRONTAL SYSTEM.
DURING PASSAGE, IT COULD BRING SIGNIFICANT SHOWERS ACROSS THE
MARIANAS, ESPECIALLY TO TINIAN AND SAIPAN, OR JUST WEST OF THE
ISLANDS. DUE TO THE UNSETTLED PATTERN FORMED BETWEEN NURI AND FORMER
INVEST 96W TO THE NORTHEAST OF THE MARIANAS, LINES OF INTENSE SHOWERS
HAVE ALREADY BEGUN FORMING UPSTREAM FROM NURI, WHICH ARE EXPECTED TO
BRING FLASH FLOODING RISK TO TINIAN AND SAIPAN AS EARLY AS TONIGHT.
AT THIS TIME, 5 TO 8 INCHES OF RAIN IS POSSIBLE OVER TINIAN AND
SAIPAN BETWEEN TONIGHT AND FRIDAY AFTERNOON, MAINLY IF 03W TREKS
CLOSER TO THE ISLANDS. HIGH UNCERTAINTY REMAINS REGARDING RAINFALL
TOTALS DUE TO THE UNCERTAINTY IN TC MOTION.
NURI'S MOVEMENT AND DEVELOPMENT CYCLE MAKES IT LESS LIKELY FOR
TROPICAL STORM FORCE WINDS TO DEVELOP OVER THE MARIANAS. EVEN SO,
WINDS ARE STILL EXPECTED TO BECOME MORE SOUTHWESTERLY AND SOMETIMES
FRESH TO STRONG, WITH AN OCCASIONAL NEAR GALE-FORCE GUST POSSIBLE
DURING THE MOST INTENSE SHOWERS BY FRIDAY. AFTER, CONDITIONS ARE
EXPECTED TO IMPROVE CONSIDERABLY AS DIFFUSIVE NORTHERLIES FOLLOW
ALONG THE LEESIDE OF SAID STORM AFTER IT EXITS TO THE NORTHEAST BY
EARLY NEXT WEEK.
