DEEP CLOUD LAYERS SWIRLED COUNTER-CLOCKWISE AROUND THE LOW CENTER... OBSCURING LOWER FEATURES MOSTLY TO COMPLETELY NORTH OF THE CURVE FROM 30N 179W TO 17N 172W TO 20N 162W TO 30N 166W. ISOLATED THUNDERSTORMS ALSO DEVELOPED NEAR THE LOW WITHIN 120 MILES OF THE CURVE FROM 27N 177W TO 21N 170W TO 18N 172W. 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 149W. ISOLATED TOWERING CUMULI FORMED UNDER THIS FEATURE WITHIN 60 MILES OF THE CURVE FROM 26N 151W TO 21N 152W TO 17N 149W. 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 16N AND 07N...MOSTLY WEST OF 147W. 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 22N...AND BLENDING INTO THE CLOUD LAYERS FORMED AROUND THE LOW ITSELF. TO THE NORTH...A PRE-FRONTAL BAND OF LOW CLOUD LAYERS EXTENDED ACROSS HAWAIIAN WATERS WITHIN 60 MILES OF THE LINE FROM 26N 163W TO 30N 151W AND FURTHER NORTHEAST. THIS SECONDARY FEATURE MOVED NORTHWEST AT AROUND 20 MILES AN HOUR...WHILE THE MAIN FRONTAL CLOUD BAND...LOCATED NORTH OF 30N...MOVED SOUTH SLOWLY. OTHERWISE...CLOUD COVER ACROSS HAWAIIAN WATERS CONSISTED MOSTLY OF STRATOCUMULUS AND CUMULUS FRAGMENTS UP TO ABOUT 120 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 THE COLD-AIR CUMULI MOVED TOWARD THE NORTHEAST TO NORTH. ACROSS THE MAIN HAWAIIAN ISLANDS...LAYERED HIGH CLOUDS FROM THE SOUTH MOSTLY OBSCURED LOWER FEATURES. WHERE LOWER CLOUDS WERE VISIBLE...THEY APPEARED FAIRLY SPARSE. THESE LOWER CLOUDS GENERALLY ROSE TO HEIGHTS OF 6000 TO 7000 FEET. RADAR DATA FROM NEAR THE ISLANDS SHOWED SCATTERED SHOWERS OFFSHORE TO THE SOUTH OF KAUAI AND OFFSHORE TO THE NORTHEAST 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.
