* WHERE...BIG ISLAND, MAUI, LANAI, MOLOKAI, AND KAHOOLAWE.
* WHEN...THROUGH SATURDAY AFTERNOON.
* IMPACTS...SIGNIFICANT FLOODING MAY OCCUR DUE TO THE OVERFLOW OF
STREAMS AND DRAINAGES. ROADS IN SEVERAL AREAS MAY BE CLOSED, ALONG
WITH PROPERTY DAMAGE IN URBAN OR LOW LYING SPOTS DUE TO RUNOFF.
LANDSLIDES MAY ALSO OCCUR IN AREAS WITH STEEP TERRAIN.
* ADDITIONAL DETAILS...

HEAVY SHOWERS TO THE BIG ISLAND, AND TO A LESSER EXTEND TO MAUI
THROUGH THE SATURDAY. WINDWARD AND SOUTHEAST BIG ISLAND, AND
WINDWARD MAUI, ARE THE MOST LIKELY TO EXPERIENCE HEAVY RAIN DUE
