DEEP CLOUD LAYERS SWIRLED COUNTER-CLOCKWISE AROUND THE LOW CENTER... OBSCURING LOWER FEATURES NORTH OF THE CURVE FROM 26N 180 TO 23N 175W TO 21N 180 TO 20N 168W TO 23N 162W TO 28N 166W TO 30N 166W. SCATTERED THUNDERSTORMS ALSO DEVELOPED SOUTHEAST OF THE LOW WITHIN 120 MILES OF THE CURVE FROM 26N 174W TO 23N 171W TO 19N 171W. THIS FEATURE AS A WHOLE REMAINED NEARLY STATIONARY. WATER VAPOR IMAGES ALSO SHOWED A WEAK AND DIFFUSE TROUGH OF LOW PRESSURE IN THE UPPER ATMOSPHERE NEAR 24N 147W. ISOLATED TOWERING CUMULI AND POSSIBLE THUNDERSTORMS FORMED UNDER THIS FEATURE WITHIN 60 MILES OF THE CURVE FROM 27N 149W TO 20N 150W. DEEP LAYERED DEBRIS CLOUDS FROM EARLIER CONVECTION PARTLY TO MOSTLY OBSCURED LOWER FEATURES TO THE EAST BETWEEN 150W AND 140W. TO THE SOUTH...LIGHT TO MODERATE THUNDERSTORM ACTIVITY CONTINUED IN THE ITCZ BETWEEN 14N AND 07N...MOSTLY WEST OF 150W. DEEP LAYERED DEBRIS CLOUDS FROM THIS AND EARLIER CONVECTION PARTLY TO MOSTLY OBSCURED LOWER FEATURES WITHIN THE SAME RANGE OF LATITUDE. HOWEVER...BETWEEN 174W AND 150W...MORE EXTENSIVE DEEP LAYERED DEBRIS CLOUDS FLOWED NORTH UNDER THE INFLUENCE OF THE LOW ALOFT AS DESCRIBED IN THE FIRST PARAGRAPH ABOVE...MOSTLY TO COMPLETELY OBSCURING LOWER FEATURES AS FAR NORTH AS 20N. OTHERWISE...CLOUD COVER ACROSS HAWAIIAN WATERS CONSISTED MOSTLY OF STRATOCUMULUS AND CUMULUS FRAGMENTS UP TO ABOUT 150 MILES ACROSS. THESE CLOUDS GENERALLY ROSE TO HEIGHTS OF 6000 TO 9000 FEET...AND MOVED TOWARD THE WEST SOUTHWEST AT 15 TO 20 MILES AN HOUR...THOUGH WEST OF 170W THEY MOVED TOWARD THE NORTHEAST TO NORTH. ACROSS THE MAIN HAWAIIAN ISLANDS...LAYERED HIGH CLOUDS FROM THE SOUTH OBSCURED THE BIG ISLAND MOSTLY...AND THE OTHER ISLANDS PARTLY. LOWER CLOUD COVER CONSISTED MAINLY OF AFTERNOON CUMULUS BUILDUPS OVER HIGHER TERRAIN INLAND...THOUGH A FEW MARINE CUMULI ALSO MOVED ASHORE ALONG SLOPES FACING EAST. AREAS WITH THE GREATEST LOW CLOUD COVER INCLUDED NORTH CENTRAL KAUAI...BOTH MOUNTAIN RANGES ON OAHU... WEST MOLOKAI...MOST OF LANAI...AND WEST SLOPES OF HALEAKALA ON MAUI. THESE CLOUDS GENERALLY ROSE TO HEIGHTS OF 5000 TO 7000 FEET. RADAR DATA FROM NEAR THE ISLANDS SHOWED SCATTERED SHOWERS OVER THE KOOLAU RANGE ON OAHU AND ALONG THE NORTHWEST COAST OF THE BIG ISLAND...BUT ISOLATED SHOWERS AT MOST ELSEWHERE. $$ RYSHKO +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ To unsubscribe from WX-TROPL send e-mail to LISTSERV@LISTSERV.ILLINOIS.EDU with "unsub wx-tropl" in the body of your message.
