VALID 00Z THU AUG 22 2024 - 00Z THU AUG 29 2024
...MONITORING TROPICAL SYSTEM DEVELOPMENT AND POSSIBLE
ISLAND/MARITIME WEEKEND IMPACTS...
LATEST MODEL AND ENSEMBLE FORECASTS GENERALLY REMAIN REASONABLY
WELL CLUSTERED THIS WEEK. A FAVORED MODEL COMPOSITE SUPPORTS QUITE
BREEZY TRADES WITH SURFACE HIGH PRESSURE BUILDING AND BRIDGING TO
THE NORTH OF THE STATE. SHOWERS ARE LIKELY TO FAVOR TYPICAL
WINDWARD/MAUKA AREAS THIS WEEK, BUT MAY OCCASIONALLY SPILL INTO
LEEWARD AREAS.
A CONSISTENT RECENT FORECAST SIGNAL CONTINUES TO SHOW DEEP
MOISTURE ADVECTING INTO AT LEAST THE BIG ISLAND BY LATER THIS
WEEKEND INTO EARLY NEXT WEEK WITH ORIGINS FROM POSSIBLE TROPICAL
LOW/CONVECTIVE DEVELOPMENTS NOW BEING MONITORED WELL TO THE
SOUTHEAST OF THE ISLANDS BY THE NATIONAL HURRICANE CENTER AND
CENTRAL PACIFIC HURRICANE CENTER. SYSTEM PROXIMITY IN THIS
SCENARIO OFFERS POTENTIAL TO SUPPORT A MUCH WETTER AND WINDY
PERIOD ALONG WITH SIGNIFICANT MARITIME HAZARDS.
