CLOUDS ARE SCATTERED OVER KAUAI COUNTY EXCEPT FOR BROKEN LOW CLOUDS OVER THE NORTHWEST THIRD OF KAUAI. THERE ARE BROKEN TO OVERCAST LOW CLOUDS OVER THE KOOLAU MOUNTAINS AND THE WEST THIRD OF OAHU WITH SCATTERED CLOUDS ELSEWHERE ON THE ISLAND. BROKEN TO OVERCAST LOW CLOUDS COVER MOST AREAS OF MAUI COUNTY AND THE BIG ISLAND OF HAWAII. THESE CLOUDS EXTEND UP TO ABOUT 10000 FEET OF ELEVATION AND BLANKET THE HUMUULA SADDLE BETWEEN MAUNA KEA AND MAUNA LOA. SKIES ARE CLEAR OVER THE SUMMITS OF MAUNA KEA AND MAUNA LOA AND ALONG SOME COASTAL AREAS. CLOUDS ARE ISOLATED OVER MOST AREAS OF KAUAI COUNTY AND OAHU WITH SCATTERED TO BROKEN LOW CLOUDS OVER THE WINDWARD SLOPES OF KAUAI AND OVER THE KOOLAU MOUNTAINS ON OAHU. BROKEN LOW CLOUDS COVER MOLOKAI AND LANAI. THERE ARE SMALL PATCHES OF BROKEN LOW CLOUDS OVER THE SLOPES OF WINDWARD WEST MAUI AND OVER EAST MAUI ABOVE HANA. CLOUDS ARE ISOLATED ELSEWHERE OVER MAUI. OVERCAST LOW CLOUDS COVER MOST OF THE EAST SIDE OF THE BIG ISLAND FROM UPOLU POINT TO HILO TO SOUTH CAPE EXCEPT FOR SCATTERED CLOUDS BETWEEN WAIPIO VALLEY AND OOKALA AND ISOLATED CLOUDS NEAR CAPE KUMUKAHI. THERE IS ALSO AN AREA OF OVERCAST LOW CLOUDS ALONG THE WEST SIDE OF THE BIG ISLAND FROM KEALAKEKUA TO KEAHOLE POINT. THE LOW CLOUDS ON THE EAST SIDE OF THE BIG ISLAND EXTEND UPSLOPE INTO THE MIDDLE OF THE HUMUULA SADDLE...TO ABOUT 6000 FEET OF ELEVATION. SKIES ARE CLEAR OVER THE REST OF THE BIG ISLAND. LOW CLOUDS NEAR THE MAIN HAWAIIAN ISLANDS ARE MOVING FROM THE EAST AT 10 TO 15 MPH. THERE ARE ISOLATED LOW CLOUDS UPSTREAM OF KAUAI... SCATTERED LOW CLOUDS UPSTREAM OF OAHU...AND SCATTERED TO BROKEN LOW CLOUDS UPSTREAM OF MAUI AND THE BIG ISLAND. THESE CLOUDS ARE MOSTLY STABLE STRATOCUMULUS WITH ISOLATED MODERATE CUMULUS CLOUDS MIXED IN. RADARS SHOW SCATTERED MODERATE SHOWERS IN AN EAST TO WEST LINE 80 MILES SOUTH OF KAUAI AND ALONG A NARROW LINE EXTENDING WEST FROM LAAU POINT ON MOLOKAI. A 100 TO 150 MILE WIDE BAND OF BROKEN TO OVERCAST LOW CLOUDS...THE REMNANT OF A FRONT...IS NORTH OF A LINE FROM 30N150W TO 250 MILES NORTH NORTHWEST OF KAUAI TO 22N167W TO 25N180W. THE PART OF THE BAND NORTHEAST OF THE ISLANDS HAS BEEN NEARLY STATIONARY OVER THE PAST SEVERAL HOURS WHILE THE PART WEST OF THE ISLANDS HAS BEEN MOVING TOWARDS THE WEST SOUTHWEST AT 15 MPH. ANOTHER FRONTAL BAND...A 130 MILE WIDE BAND OF OVERCAST LOW CLOUDS...IS NORTH OF A LINE FROM 30N160W TO 28N170W TO 30N178W. THIS BAND HAS BEEN MOVING TOWARD THE SOUTH AT 20 MPH. A 350 MILE WIDE BAND OF BROKEN TO OVERCAST LAYERED CLOUDS ALONG THE INTERTROPICAL CONVERGENCE ZONE...ITCZ...IS SOUTH OF A LINE FROM 14N140W TO 13N160W TO 10N180W. THERE ARE SCATTERED TOWERING CUMULUS CLOUDS WITHIN THE BAND EAST OF 150W AND SCATTERED CUMULONIMBUS CLOUDS... CB...WEST OF 150W. A 200 MILE DIAMETER CLUSTER OF CB ASSOCIATED WITH A SMALL TROPICAL DISTURBANCE IS CENTERED NEAR 08N173W. THE DISTURBANCE HAS BECOME WEAK AND IS NEARLY INDISTINGUISHABLE FROM THE REST OF THE ITCZ. WATER VAPOR IMAGERY...WHICH SHOWS FEATURES MAINLY ABOVE 24000 FT... SHOWS A LOW ALOFT 270 MILES SOUTH SOUTHWEST OF KAUAI NEAR 18N161W. THERE ARE NO HIGH CLOUDS AROUND THE LOW SO THE LOW CAN BE SEEN ON WATER VAPOR IMAGERY BUT NOT ON VISIBLE OR WINDOW IR IMAGERY. $$ DONALDSON +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ To unsubscribe from WX-TROPL send e-mail to LISTSERV@LISTSERV.ILLINOIS.EDU with "unsub wx-tropl" in the body of your message.
