LOW CLOUD MOTION IS FROM THE EAST AT 10 TO 15 MPH ACROSS THE ISLAND CHAIN. A FRONT IS FAR NORTHWEST OF KAUAI AND HAS BEEN PUSHING EAST AT 35 TO 40 MPH ALONG 30N OVER THE PAST SEVEN HOURS. AN AREA OF SHOWERS AND THUNDERSTORMS HAS RECENTLY FORMED ALONG THE LEADING EDGE OF THE BOUNDARY. MOST OF THE CONVECTION IS CURRENTLY WITHIN 60 MILES EITHER SIDE OF A LINE FROM 30N172W TO 25N175W TO 25N177.5W TO 23.5N179.5E. THE FRONT HAS PASSED MIDWAY ATOLL...WHERE THE LATEST SURFACE OBSERVATIONS INDICATE FEW TO SCATTERED LOW CLOUDS...REDUCED VISIBILITY DUE TO MIST...AND WINDS FROM THE NORTHWEST AROUND 15 MPH GUSTING TO 25 MPH.
