THIS LOW IS MOVING TO THE EAST AT 15 MPH. ISOLATED CUMULONIMBUS CLOUDS ARE LOCATED SOUTHEAST OF THE LOW...GENERALLY FROM 12N TO 15N BETWEEN 166W AND 171W. CLOUD TOPS EXTEND UP TO 36000 FT. INDIVIDUAL CONVECTIVE CELLS ARE SHORT LIVED AND ARE MOVING TO THE EAST NORTHEAST AT 10 TO 15 MPH. CIRRUS DEBRIS CLOUDS FROM THE EARLY CONVECTION ARE MOVING TO THE NORTHEAST AT 30 TO 40 MPH. THE LOW IS PART OF A LONGWAVE TROUGH THAT EXTENDS NORTH THROUGH 30N168W. BROKEN LAYERED CLOUDS ARE LOCATED EAST OF THE TROUGH... GENERALLY BETWEEN 153W AND 167W...COVERING MUCH OF THE MAIN HAWAIIAN ISLANDS. THESE CLOUDS ARE MOVING TO THE NORTH NORTHEAST AT 50 TO 60 MPH. ISOLATED CUMULONIMBUS CLOUDS ARE EMBEDDED WITHIN THE LAYERED CLOUDS...GENERALLY NORTH OF 22N BETWEEN 159W AND 164W. INDIVIDUAL CONVECTIVE CELLS ARE MOVING TO THE NORTH NORTHEAST AT 20 MPH. CLOUD TOPS EXTEND UP TO 40000 FT. ADDITIONAL CUMULONIMBUS CLOUDS ARE LOCATED SOUTH OF 12N BETWEEN 151W AND 159W. THESE CLOUDS ARE LOCATED ALONG A PORTION OF THE INTERTROPICAL CONVERGENCE ZONE. CLOUD TOPS WITHIN THIS AREA EXTEND UP TO 50000 FT. CIRRUS DEBRIS CLOUDS FROM THIS CONVECTION EXTEND NORTHWARD...AND MERGE WITH THE MIDDLE AND HIGH LEVEL LAYERED CLOUDS DESCRIBED ABOVE. FARTHER EAST...AREAS OF LOW CLOUDS ARE EMBEDDED WITHIN A RETURNING TRADE WIND FLOW. BASED ON LOW-CLOUD MOTIONS...A SURFACE RIDGE IS LOCATED FROM 28N140W TO NEAR 27N152W. NORTH OF 24N...CLOUDS ARE BROKEN TO OVERCAST IN COVERAGE AND ARE COMPOSED PRIMARILY OF STABLE CLOSED CELL CUMULUS ELEMENTS. SOUTH OF 24N...CLOUDS ARE GENERALLY SCATTERED TO BROKEN IN COVERAGE AND ARE COMPOSED PRIMARILY OF SHOWERY OPEN CELL CUMULUS ELEMENTS. NORTH OF THE RIDGE...CLOUD MOTIONS ARE TO THE NORTH AND NORTHEAST AT 10 TO 15 MPH. SOUTH OF THE RIDGE...CLOUD MOTIONS ARE TO THE WEST AND NORTHWEST AT 10 TO 15 MPH. SOUTH OF 22N...CLOUD MOTIONS ARE TO THE WEST AT 25 TO 30 MPH. THE WIDESPREAD MIDDLE AND HIGH LEVEL LAYERED CLOUDS NEAR THE STATE ARE BEGINNING TO SHOW SOME BREAKS IN COVERAGE. HOWEVER...THEY CONTINUE TO OBSCURE MOST LOW-CLOUD FEATURES ACROSS THE MAIN HAWAIIAN ISLANDS. THE CLOUDS ARE THICKEST ACROSS MAUI COUNTY...FROM THE COASTAL WATERS SOUTH AND EAST OF OAHU TO THE COASTAL WATERS JUST WEST OF THE BIG ISLAND. CLOUD TOPS WITHIN THIS AREA EXTEND UP TO 20000 FT. THESE CLOUDS ARE MOVING TO THE NORTH NORTHEAST AT 15 TO 20 MPH. $$ BRAVENDER +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ To unsubscribe from WX-TROPL send e-mail to LISTSERV@LISTSERV.ILLINOIS.EDU with "unsub wx-tropl" in the body of your message.
