THE LOW IS NEARLY STATIONARY...AND THE TROUGH IS MOVING TO THE EAST AT 30 MPH. A 300 MILE WIDE BAND OF CLOUDS ASSOCIATED WITH THIS TROUGH IS LOCATED GENERALLY EAST OF A LINE FROM 30N175W TO 26N180...OR FROM ABOUT 225 MILES NORTHEAST OF MIDWAY ATOLL TO 225 MILES SOUTHWEST OF MIDWAY. THIS AREA OF CLOUDS IS COMPOSED PRIMARILY OF BROKEN CUMULUS AND TOWERING CUMULUS ELEMENTS. THESE CLOUDS ARE MOVING TO THE NORTHEAST AT 20 TO 30 MPH. ISOLATED CUMULONIMBUS CLOUDS ARE ALSO EMBEDDED WITHIN THIS CLOUD BAND. THESE CLOUD TOPS EXTEND UP TO 42000 FT. BROKEN CIRRUS AND CIRROCUMULUS CLOUDS ARE ALSO LOCATED THROUGHOUT THIS AREA. THESE HIGH CLOUDS ARE LOCATED GENERALLY NORTH OF 19N WEST OF 170W...AND NORTH OF 27N WEST OF 160W. THESE CLOUDS ARE MOVING TO NORTHEAST AND EAST AT 60 TO 70 MPH. A SECOND AREA OF LAYERED CLOUDS IS LOCATED GENERALLY BETWEEN 13N AND 21N EAST OF 151W. LOW CLOUDS IN THIS AREA ARE MOVING TO THE WEST AT AROUND 20 MPH. MIDDLE AND HIGH LAYER CLOUDS IN THIS AREA ARE MOVING TO THE NORTHEAST AT 15 TO 20 MPH. FARTHER TO THE NORTH...A 300 MILE WIDE BAND OF CLOUDS IS ASSOCIATED WITH A NEARLY STATIONARY FRONT. THE LEADING EDGE OF THESE CLOUDS EXTENDS FROM 30N138W TO 25N146W. THE BAND IS COMPOSED PRIMARILY OF BROKEN TO OVERCAST CUMULUS AND STRATOCUMULUS ELEMENTS...WITH EMBEDDED TOWERING CUMULUS ELEMENTS. THIS BAND OF CLOUDS IS NEARLY STATIONARY. AREAS OF BROKEN TO OVERCAST LOW CLOUDS ARE LOCATED FARTHER SOUTHWEST FROM THIS AREA... EXTENDING TOWARD THE MAIN HAWAIIAN ISLANDS. THESE CLOUDS ARE COMPOSED PRIMARILY OF SHOWERY OPEN CELL CUMULUS CLOUDS ELEMENTS... AND ARE MOVING TO THE SOUTHWEST AT 10 TO 15 MPH. ACROSS THE MAIN HAWAIIAN ISLANDS...BROKEN TO OVERCAST LOW CLOUDS COVER THE EASTERN HALF OF KAUAI...AND EXTEND UP TO 100 MILES UPSTREAM TO THE NORTHEAST AND EAST. A NARROW BAND OF LOW CLOUDS ALSO EXTENDS 120 MILES OFFSHORE TO THE WEST...COVERING A PORTION OF NIIHAU. BROKEN TO OVERCAST LOW CLOUDS COVER THE SLOPES OF THE KOOLAU AND WAIANAE RANGES ON OAHU. THESE CLOUDS EXTEND 60 MILES UPSTREAM TO THE NORTHEAST...AND 15 MILES DOWNSTREAM TO THE SOUTHWEST OF THE ISLAND. BROKEN LOW CLOUDS COVER THE INTERIOR AND SOUTHERN SECTIONS OF MOLOKAI AND OF LANAI. BROKEN LOW CLOUDS COVER THE INTERIOR OF THE WEST MAUI MOUNTAINS. BROKEN TO OVERCAST LOW CLOUDS COVER THE LOWER SLOPES OF HALEAKALA BELOW 7000 FT. THESE CLOUDS EXTEND OFFSHORE UP TO 60 MILES UPSTREAM TO THE NORTHEAST AND EAST OF MAUI. ON THE BIG ISLAND...BROKEN TO OVERCAST CLOUDS COVER WINDWARD SECTIONS FROM NORTH KOHALA TO PUNA DISTRICTS GENERALLY BELOW 7000 FT. BROKEN CLOUDS COVER KAU DISTRICT BELOW 9000 FT. BROKEN CLOUDS ALSO COVER NORTH AND SOUTH KONA AND SOUTH KOHALA DISTRICTS BELOW 9000 FT...ALTHOUGH THE IMMEDIATE COASTLINES ARE MOSTLY CLEAR. THE EXCEPTION IS FROM MILOLII SOUTHWARD...WHERE A 20 MILE WIDE BAND OF CLOUDS EXTENDS 120 MILES OFFSHORE TO THE WEST SOUTHWEST. WHILE THE SUMMITS OF MAUNA KEA AND MAUNA LOA ARE FREE OF CLOUDS...THE SNOWPACK ABOVE 11000-12000 FT IS BLENDING IN WITH THE CLOUDS THAT HAVE DEVELOPED ACROSS THE MIDDLE SLOPES. $$ BRAVENDER +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ To unsubscribe from WX-TROPL send e-mail to LISTSERV@LISTSERV.ILLINOIS.EDU with "unsub wx-tropl" in the body of your message.
