TROPICAL STORM DARBY IS NOW CENTERED JUST WEST OF THE BIG ISLAND

WARNINGS AND FLASH FLOOD WATCHES ARE IN EFFECT OVER THE STATE.
DARBY HAS AN ANALOG PERHAPS CLOSEST TO BUT SLIGHTLY MORE NORTHWARD
SHIFTED TRACK THAN ISELLE 2014 THAT PRODUCED OVER 15" OF RAIN OVER
FAVORED WINDWARD TERRAIN OF THE BIG ISLAND. PLEASE REFER TO THE
LATEST PRODUCTS AND WARNINGS/ADVISORIES FROM CPHC AND WFO HONOLULU
FOR THIS DANGEROUS STORM.

EXPECT A RETURN TO A MODERATE TO LOCALLY BRISK TRADE PATTERN
MIDWEEK INTO NEXT WEEKEND IN THE WAKE OF DARBY AS HIGH PRESSURE
BECOMES ESTABLISHED NNE OF THE ISLANDS. SHOWERS WOULD BE MAINLY
CONFINED TO FAVORED WINDWARD TERRAIN FUELED IN PART BY SLOWLY
DECAYING MOISTURE ASSOCIATED WITH THE HEAVY RAINFALL EARLIER VIA
DARBY.
