...OUTER BANDS EAST OF NOLO ARE EXPECTED TO BRING ADDITIONAL
PERIODS OF HEAVY RAIN TO THE WESTERN ISLANDS THROUGH THURSDAY...
HURRICANE NOLO IS FORECAST TO DRIFT SLOWLY WEST AWAY FROM THE
WESTERN ISLANDS EARLY IN THE PERIOD BEFORE AN UPPER RIDGE
BUILDING NORTH OF STORM BEGINS TO ACCELERATE THE STORM TOWARD THE
INTERNATIONAL DATE LINE BY THE WEEKEND. THE EASTERN OUTER BANDS OF
THE STORM ARE LIKELY TO CONTINUE TO IMPACT THE WESTERN ISLANDS
THROUGH THURSDAY, POTENTIALLY PRODUCING ADDITIONAL HEAVY
ACCUMULATIONS ACROSS PORTIONS OF NIIHAU, KAUAI, AND OAHU. REFER
TO THE ADVISORIES/STATEMENTS FROM THE NATIONAL HURRICANE CENTER
FOR THE LATEST INFORMATION REGARDING HURRICANE NOLO.
AS THE STORM MOVES WEST, SOUTHEASTERLY WINDS ACROSS THE ISLANDS
WILL GRADUALLY WEAKEN, REPLACED BY MORE EASTERLY TO NORTHEASTERLY
FLOW AND NOTABLY DRIER AIR BY THE WEEKEND.
AN UPPER LOW IS FORECAST TO CLOSE OFF AND SETTLE SOUTH, WELL TO
THE NORTHEAST OF THE ISLANDS EARLY NEXT WEEK. A SURFACE LOW
APPROACHING FROM THE NORTHEAST IS EXPECTED TO DISSIPATE NORTH OF
THE ISLANDS, BUT PUSH A WEAK FRONT INTO THE STATE EARLY NEXT
WEEK.
