CLOUDS ARE SCATTERED OVER KAUAI COUNTY EXCEPT FOR BROKEN LOW CLOUDS OVER WINDWARD KAUAI. BROKEN TO OVERCAST LOW CLOUDS COVER OAHU. VISIBLE IMAGERY JUST BEFORE SUNSET SHOWED THAT MANY OF THE CLOUDS OVER OAHU WERE WAVE CLOUDS...A SERIES OF CLOSELY SPACED CLOUD LINES PARALLEL TO THE KOOLAU MOUNTAINS. THERE ARE SCATTERED CLOUDS OVER MAUI COUNTY EXCEPT FOR SMALL PATCHES OF BROKEN LOW CLOUDS OVER WINDWARD AREAS. CLOUDS ARE ISOLATED OVER MOST OF THE BIG ISLAND OF HAWAII BUT THERE ARE BROKEN TO OVERCAST LOW CLOUDS ALONG THE COAST AND LOWER SLOPES FROM NAALEHU TO SOUTH POINT TO KAILUA-KONA. LOW CLOUDS NEAR THE MAIN HAWAIIAN ISLANDS ARE MOVING FROM THE NORTHEAST AT 20 TO 25 MPH...FROM A MORE NORTHERLY DIRECTION THAN THE TYPICAL EAST NORTHEAST TRADE-WIND FLOW. THERE ARE BROKEN LOW CLOUDS UPSTREAM OF THE ISLANDS FROM THE BIG ISLAND TO OAHU. CLOUDS ARE ISOLATED FOR 120 MILES UPSTREAM OF KAUAI. A BAND OF SHOWERS ALONG THE TRAILING END OF A FRONT IS MOVING TOWARD THE MAIN HAWAIIAN ISLANDS FROM THE NORTHEAST. THE BAND LIES NORTH OF A LINE FROM 120 MILES NORTHEAST OF LIHUE...TO 50 MILES NORTHEAST OF MOLOKAI...TO 120 MILES NORTHEAST OF HILO...TO 21N150W...350 MILES EAST NORTHEAST OF HILO TO 25N140W. THE PART OF THE BAND NEAR 140W IS 120 MILES AND CONTAINS SHOWERY OVERCAST LOW CLOUDS. THE BAND NARROWS TO 90 MILES WIDE WEST OF 145W AND THE CLOUD COVERAGE BECOMES BROKEN. THE PART OF THE BAND EAST OF 150W HAS BEEN MOVING TOWARD THE SOUTHEAST AT 12 MPH. THE PART OF THE BAND NORTHEAST OF THE ISLANDS HAS BEEN MOVING TOWARD THE SOUTHWEST AT 15 TO 20 MPH SO THE BAND SHOULD REACH THE ISLANDS IN THE NEXT FEW HOUR. THE CLOUDS UPSTREAM OF THE ISLANDS ARE A MIX OF STABLE STRATOCUMULUS CLOUDS AND SHOWERY CUMULUS CLOUDS WITH TOPS TO 10000 FT. THE SHOWER AREA THAT MOVED OVER THE MAIN HAWAIIAN ISLANDS FRIDAY NIGHT THROUGH SATURDAY AFTERNOON IS NOW WEST OF THE ISLANDS. THE 180 MILE WIDE CLOUD AREA IS CENTERED ALONG A LINE FROM 135 MILES SOUTHWEST OF KAUAI TO 23N167W. THIS CLOUD AREA HAS BEEN MOVING TOWARD THE WEST AT 20 MPH. THERE IS AN UNUSUAL DOUBLE CLOUD BAND IN THE DEEP TROPICS SOUTH OF THE HAWAIIAN ISLANDS. A BAND OF BROKEN LAYERED CLOUDS...SCATTERED TOWERING CUMULUS CLOUDS AND ISOLATED CUMULONIMBUS CLOUDS LIES SOUTH OF A LINE FROM 10N140W TO 14N175W. MOST OF THE BAND IS BETWEEN 300 AND 400 MILES WIDE...BUT THE BAND NARROWS TO 180 MILES WIDE WEST OF 168W. THE MOST ACTIVE THUNDERSTORMS ARE BETWEEN 145W AND 150W AND MAY BE ASSOCIATED WITH A WEAK LOW. A 200 TO 250 MILE WIDE BAND OF SHOWERY BROKEN LOW CLOUDS AND SCATTERED TOWERING CUMULUS CLOUDS IS CENTERED FROM 13N140W TO 14N150W TO 15N165W. WATER VAPOR IMAGERY...WHICH SHOWS FEATURES MAINLY ABOVE 24000 FT... SHOWS A CYCLONE ALOFT ABOUT 900 MILES NORTHEAST OF THE MAIN HAWAIIAN ISLANDS NEAR 31N147W. A TROUGH EXTENDS SOUTHWEST FROM THE LOW TO 26N150W. AN ANTICYCLONE ALOFT IS CENTERED 357 MILES WEST NORTHWEST OF KAUAI NEAR 24N166W. $$ DONALDSON +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ To unsubscribe from WX-TROPL send e-mail to LISTSERV@LISTSERV.ILLINOIS.EDU with "unsub wx-tropl" in the body of your message.
