Squeezed March 19, 2006

While Kauai tries to keeps its damaged dams from breaking once more, the heavy stuff is now reaching Oahu. Oahu is now under a flash flood warning until 2:00 p.m.

The state remains under a flash flood watch until Monday afternoon, but the weather services believes that more wet stuff is coming:

MODERATE TO HEAVY SHOWERS PERSIST ACROSS SOUTHEAST PORTIONS OF THE
BIG ISLAND. ADDITIONAL HEAVY SHOWERS AND THUNDERSTORMS ARE CURRENTLY
BLOSSOMING OVER AND AROUND OAHU AS WELL…AND SIGNIFICANT SHOWERS
CAN ALSO BE SEEN ALONG THE SOUTHERN SLOPES OF MOUNT HALEAKALA. THESE
CONDITIONS WILL CONTINUE OVER ALL THE ISLANDS THROUGH THE DAY AND
INTO THE COMING WEEK AS A MID AND UPPER LEVEL TROUGH OF LOW PRESSURE

TROUGH OVER THE CENTRAL ISLANDS WILL HELP SUPPORT STRONG CONVECTION

REMAINS RIPE FOR THUNDERSTORMS WITH HEAVY RAINFALL AND POSSIBLE
