A BAND OF DEEP LAYERED CLOUDS WITH EMBEDDED ISOLATED TOWERING CUMULI AND POSSIBLE THUNDERSTORMS EXTENDED ACROSS HAWAIIAN WATERS WITHIN 200 MILES OF THE CURVE FROM 17N 180 TO 27N 172W TO 30N 171W AND FURTHER SOUTHWEST AND NORTHWEST. LAYERED HIGH TO MIDDLE CLOUDS OF VARYING THICKNESS ALSO PARTLY OBSCURED LOWER FEATURES SOUTHEAST UP TO ABOUT 325 MILES FROM THE LEADING EDGE OF THE MAIN CLOUD BAND. THIS FEATURE AS A WHOLE MOVED EAST SLOWLY. ANOTHER BAND OF LOW TO MIDDLE CLOUD LAYERS ASSOCIATED WITH A SECOND FRONT EXTENDED ACROSS HAWAIIAN WATERS WITHIN 140 MILES OF THE CURVE FROM 30N 166W TO 27N 151W TO 30N 140W AND FURTHER NORTHEAST. DENSELY PACKED COLD-AIR CUMULI PREVAILED BETWEEN THIS BAND AND 30N. THIS FEATURE MOVED SOUTH AT 10 TO 15 MILES AN HOUR. TO THE SOUTH...LIGHT THUNDERSTORM ACTIVITY CONTINUED IN THE ITCZ BETWEEN 14N AND 07N. LAYERED MIDDLE TO HIGH DEBRIS CLOUDS FROM THIS AND EARLIER CONVECTION PARTLY TO MOSTLY OBSCURED LOWER FEATURES FROM 14N TO 02N. ISOLATED TOWERING CUMULI AND POSSIBLE THUNDERSTORMS DEVELOPED WITHIN 150 MILES OF THE POINT 19N 154W. LAYERED MIDDLE TO HIGH DEBRIS CLOUDS FROM THIS AND EARLIER CONVECTION MOSTLY TO PARTLY OBSCURED LOWER FEATURES WITHIN 250 MILES OF THE POINT 19N 151W. OTHERWISE...CLOUD COVER ACROSS HAWAIIAN WATERS CONSISTED MAINLY OF UNORGANIZED CLUMPS OF MARINE CUMULUS AND STRATOCUMULUS. THESE CLUMPS VARIED IN SIZE FROM INDIVIDUAL SMALL CUMULI TO COLLECTIONS ABOUT 400 MILES ACROSS. THEY OCCURRED THROUGHOUT THE AREA...BUT WERE MOST COMMON AND LARGEST BETWEEN 140W AND 150W. THESE CLOUDS FORMED AND DISSIPATED PERIODICALLY...BUT REMAINED NEARLY STATIONARY. ACROSS THE MAIN HAWAIIAN ISLANDS...CLOUD COVER CONSISTED MOSTLY OF MARINE STRATOCUMULI MOVING ASHORE ALONG SOUTHEAST SLOPES OF KAUAI... AND ALONG PARTS OF MAUI COUNTY BORDERING THE PAILOLO CHANNEL. THIN HIGH CLOUD LAYERS ALSO STILL OBSCURED THE VICINITY OF CAPE KUMUKAHI ON THE BIG ISLAND. RADAR DATA FROM NEAR THE ISLANDS SHOWED SCATTERED SHOWERS OFFSHORE TO THE SOUTHWEST OF MAUI COUNTY AND TO THE SOUTHEAST OF THE BIG ISLAND...BUT ISOLATED SHOWERS AT MOST ELSEWHERE. THE LOWER CLOUDS GENERALLY ROSE TO HEIGHTS OF 5000 TO 7000 FEET. $$ RYSHKO +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ To unsubscribe from WX-TROPL send e-mail to LISTSERV@LISTSERV.ILLINOIS.EDU with "unsub wx-tropl" in the body of your message.
