KAUAI AND IS NOW MOVING WESTWARD SLOWLY. THIS WILL...IN TIME...PULL
THE WET WEATHER NOW OVER THE ISLANDS WESTWARD WITH THE HELP OF AN
UPPER RIDGE TO THE EAST OF THE STATE. IN THE MEANTIME...WET WEATHER
REMAINS IN THE FORECAST AS A MOIST CONVERGENT SOUTHERLY FLOW
CONTINUES TO BRING CONVECTIVE RAINS UP OVER MAUI COUNTY AND THE BIG
ISLAND...AND MORE LAYERED CLOUD AND GENERAL RAINS UP OVER OAHU AND
KAUAI. THIS WILL BE THE PATTERN THROUGH WEDNESDAY NIGHT...WITH A
GRADUAL WESTWARD SHIFT OF THE HEAVIER RAINFALL FOCUS. THERE MAY BE
SOME CLEARING BY THURSDAY...ESPECIALLY OVER THE EASTERN END OF THE
