AS FAR AS I CAN TELL FROM THE SATELLITE IMAGERY...RADAR IMAGERY AND SURFACE OBSERVATIONS...LOW CLOUDS ARE ISOLATED OVER MOST AREAS OF THE ISLANDS. SATELLITE LOOPS SHOW ONLY ISOLATED LOW CLOUDS IMMEDIATELY UPSTREAM OF THE MAIN HAWAIIAN ISLANDS. LOW CLOUD MOTIONS EAST OF THE BIG ISLAND ARE FROM THE EAST SOUTHEAST AT 10 TO 15 MPH BACKING TO EAST AT 20 MPH NEAR KAUAI. A CLOUD VORTEX OR SPIRAL IS CENTERED 210 MILES NORTHEAST OF KAHULUI AT 23N 154W. THIS FEATURE HAS BEEN MOVING SLIGHTLY NORTH OF WEST AT 13 MPH. THE VORTEX HAS WEAKENED QUITE A BIT SINCE LAST EVENING. THE VORTEX IS NOW POORLY ORGANIZED AND CONTAINS ONLY BROKEN LOW CLOUDS. WATER VAPOR IMAGERY SHOWS A PERSISTENT HIGH AMPLITUDE PATTERN OVER THE CENTRAL NORTH PACIFIC WITH ACTIVE WEATHER EAST AND WEST OF THE MAIN HAWAIIAN ISLANDS. ONE LOW IS CENTERED 1000 MILES WEST OF KAUAI AT 21N175W. OVER THE PAST SEVERAL HOURS THE LOW HAS MOVED TOWARD THE EAST AT 10 MPH. THERE ARE BROKEN LAYERED CLOUDS FROM 18N TO 30N BETWEEN 165W AND 177W. A 200 MILE WIDE BAND OF SCATTERED CUMULONIMBUS CLOUDS WITH TOPS TO 48000 FT IS CENTERED FROM 20N169W TO 26N171W. A SECOND LOW ALOFT IS CENTERED 520 MILES NORTHEAST OF HILO AT 24N148W. THERE ARE SCATTERED TOWERING CUMULUS CLOUDS...TCU...AND ISOLATED CUMULONIMBUS CLOUDS...CB...FROM 22N TO 27N BETWEEN 146W AND 150W AND ALSO WITHIN 90 MILES OF A LINE FROM 19N144W TO 16N145W TO 17N151W. THE LAYERED CLOUDS SOUTH OF 20N HAVE THINNED AND THE CONVECTION IN THAT AREA HAS WEAKENED OVER THE PAST SEVERAL HOURS. THERE IS A RIDGE ALOFT BETWEEN THE LOW WEST OF THE MAIN HAWAIIAN ISLANDS AND THE ONE TO THE EAST. A JET STREAM CURVES OVER THE TOP OF THE RIDGE FROM 12N180W TO KAUAI TO 10N140W. BROKEN TO OVERCAST HIGH CLOUDS SOUTH ASSOCIATED WITH THE JET COVER THE MAIN HAWAIIAN ISLANDS. $$ DONALDSON +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ To unsubscribe from WX-TROPL send e-mail to LISTSERV@LISTSERV.ILLINOIS.EDU with "unsub wx-tropl" in the body of your message.
