SITUATION OVERVIEW

------------------



Calvin has become a post-tropical cyclone, and therefore have 

discontinued all Tropical Storm Warnings for the Big Island. Calvin 

will continue tracking away to the west this afternoon and tonight 

with a decreasing trend for rainfall, wind and east shore surf.



Breezy trade winds will continue around the islands due to the 

pressure difference between Calvin and the subtropical high to the 

north and northeast. A Wind Advisory will remain in effect for the 

rest of the day, with winds likely falling below advisory criteria 

by this evening. Trades will usher in scattered showers focused over 

windward areas, occasionally spilling over to leeward sides of the 

islands. A Flood Watch remains in effect through this afternoon with 

additional rainfall expected up to 2 inches maximum statewide.



A High Surf Advisory remains in effect through this afternoon for 

east facing shores of Kauai, Oahu, Molokai, Maui and Big Island. The 

threat of coastal impacts from surf and storm surge will lower 

quickly this afternoon for all areas.



NEXT UPDATE

-----------



As it pertains to this event...this will be the last local statement 

issued by the National Weather Service in Honolulu HI regarding the 

effects of tropical cyclone hazards upon the area.
