A BROAD SWATH OF LAYRED CLOUDS WITH ISOLATED POCKETS OF DEEP CONVECTION IS SEEN ON THE EAST SIDE OF THIS LOW PRESSURE SYSTEM. SOME HIGH CIRRUS CLOUDS ON THE FAR EAST SIDE OF THIS SWATH OF CLOUDS IS OCCASIONALLY MOVING OVER PORTIONS OF THE STATE ESPECIALLY IN THE VICINITY OF KAUAI.

WATER VAPOR IMAGERY ALSO SHOWS AN UPPER LOW SPINNING A FEW HUNDRED MILES TO THE SOUTHEAST OF THE BIG ISLAND. ISOLATED THUNDERSTORMS ARE SEEN PULSING NEAR THE CENTER OF THE UPPER LOW AS WELL AS ALONG THE ITCZ ON THE SOUTH SIDE OF THE UPPER LOW. THIS UPPER LOW APPEARS TO BE DRIFTING SLOWLY OFF TO THE EAST.
