SCATTERED THUNDERSTORMS DEVELOPED WITHIN 150 MILES OF THE POINT 27N 169W...WITHIN 75 MILES OF THE LINE FROM 23N 170W TO 28N 158W...AND WITHIN 150 MILES OF THE LINE FROM 16N 178W TO 18N 171W. ASSOCIATED DEEP CLOUD LAYERS OBSCURED LOWER FEATURES BETWEEN THE CURVE FROM 28N 180 TO 27N 179W TO 27N 171W TO 30N 170W AND THE CURVE FROM 21N 180 TO 21N 172W TO 15N 174W TO 30N 148W. HIGH CLOUD LAYERS ALSO WERE PRESENT UP TO ABOUT 250 MILES FURTHER SOUTHEAST. ALTHOUGH THE CLOUDS MAKING UP THIS FEATURE MOVED DIFFERENTLY DEPENDING ON HEIGHT AND LOCATION... THE FEATURE AS A WHOLE REMAINED NEARLY STATIONARY. MARINE STRATOCUMULI AND LOW TO MIDDLE STRATUS LAYERS ORGANIZED INTO NOTICEABLE CLUMPS AS WIND CONVERGED ALONG AN AXIS SOUTHEAST OF THE FRONTS. THIS AREA OF CONVERGENCE WAS LOCATED WITHIN 180 MILES OF THE LINE FROM 18N 160W TO 26N 140W AND FURTHER NORTHEAST. CLOUDS NEAR THE SOUTHWEST END OF THIS FEATURE WERE FAIRLY WELL DEVELOPED...EVEN INCLUDING A THUNDERSTORM. TO THE SOUTH...VERY LIGHT THUNDERSTORM ACTIVITY CONTINUED IN THE ITCZ BETWEEN 12N AND 07N. LAYERED MIDDLE TO HIGH DEBRIS CLOUDS FROM THIS AND EARLIER CONVECTION MOSTLY TO PARTLY OBSCURED LOWER FEATURES FROM 13N TO 04N. OTHERWISE...CLOUD COVER ACROSS HAWAIIAN WATERS CONSISTED MAINLY OF FRAGMENTED MARINE STRATOCUMULI AND CUMULI...THOUGH A FEW CLUMPS UP TO 250 MILES ACROSS DID OCCUR. THESE CLOUDS GENERALLY MOVED TOWARD THE WEST AT AROUND 15 MILES AN HOUR...THOUGH AS THEY APPROACHED THE FRONTS THEY TURNED TOWARD THE NORTHWEST AND THEN THE NORTH. THEY ROSE TYPICALLY TO HEIGHTS OF 6000 TO 9000 FEET...THOUGH TALLER CUMULI AND HIGHER CLOUD LAYERS APPROACHED 15000 FEET. ACROSS THE MAIN HAWAIIAN ISLANDS...THIN LAYERED HIGH CLOUDS OBSCURED KAUAI COUNTY MOSTLY...BUT MAUI COUNTY AND OAHU PARTLY. WHERE IT WAS VISIBLE...LOWER CLOUD COVER CONSISTED MOSTLY OF LAYERED DEBRIS CLOUDS FROM DAYTIME CUMULUS BUILDUPS INLAND...THOUGH A FEW MARINE CUMULI ALSO MOVED ASHORE ALONG SLOPES FACING EAST. AREAS WITH THE GREATEST CLOUD COVER INCLUDED CENTRAL WEST KAUAI...CENTRAL LANAI... THE WEST MAUI MOUNTAINS...MIDDLE SLOPES OF HALEAKALA ON MAUI...MOST MIDDLE SLOPES OF THE BIG ISLAND...AND THE HAMAKUA COAST ON THE BIG ISLAND. THESE LOWER CLOUDS GENERALLY ROSE TO HEIGHTS OF 5000 TO 7000 FEET. RADAR DATA FROM NEAR THE ISLANDS SHOWED SCATTERED SHOWERS WELL OFFSHORE TO THE NORTHWEST OF THE BIG ISLAND...AND SCATTERED SHOWERS JUST OFFSHORE FROM THE EAST 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.
