THOUGH LOW CLOUD COVERAGE IS SCATTERED TO LOCALLY BROKEN ACROSS THE ISLANDS WINDWARD WATERS...THEY ARE ALL CARRYING SHOWERS. WEATHER RADAR SHOWS THEM MOVING FROM EAST TO WEST WITH THE TRADE WIND FLOW AT 15 TO 20 MPH. THE WINDWARD AND MOUNTAIN AREAS OF ALL THE MAJOR ISLANDS ARE CURRENTLY EXPERIENCING PASSING SCATTERED SHOWERS. FOR THE SMALLER ISLANDS...A FEW OF THE SHOWERS WOULD MANAGE TO SURVIVE THE TRIP OVER THE MOUNTAINS AND END UP OVER THE LEEWARD SECTIONS. TO THE CONTRARY...THE LEEWARD WATERS ARE ALMOST SHOWER/FREE. AS FOR THE BIG ISLAND...THE CONVECTIVE CLOUDS OF FRIDAY AFTERNOON IS FINALLY DISSIPATING ACROSS THE KONA DISTRICT AND ADJACENT WATERS. WEATHER RADAR IS STILL SHOWING A COUPLE OF HOLD OVER SHOWERS ALONG THE SHORELINE BETWEEN KAILUA KONA AND CAPTAIN COOK. OTHERWISE...SKIES ARE FAIR OVER THE KAU SLOPES...THE KAMUELA AND LEEWARD KOHALA AREAS. SATELLITE IMAGERY SHOWS A BIT MORE ORGANIZE CLUMP OF SHOWER BEARING CLOUDS UPWIND OF MAUI AND THE BIG ISLAND. SHOULD THESE AREAS HOLD TOGETHER...THEY WILL GIVE SOME OF THE ISLANDS A FEW SHOWERS LATER TODAY. WATER VAPOR IMAGERY SHOWS AN UPPER LOW OR A DEEP TROUGH JUST EAST AT OF THE BIG ISLAND AT 21N152W MOVING WEST 15 MPH. A WEAK LOW ABOUT 700 MILE SOUTHWEST OF OAHU NEAR 12N164W IS MUCH WEAKER NOW THAT THE DEEP CONVECTION HAS JUST ABOUT COLLAPSED LEAVING A COUPLE OF SMALL CELL IN ITS WAKE. THE INTERTROPICAL CONVERGENCE ZONE /ITCZ/ IS RELATIVELY QUITE WITH A COUPLE OF SMALL CLUSTERS OF THUNDERSTORMS. THE ITCZ IS STILL 300 MILES WIDE EXTENDING FROM 08N140W TO 08N160W TO 05N170W. $$ LAU +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ To unsubscribe from WX-TROPL send e-mail to LISTSERV@LISTSERV.ILLINOIS.EDU with "unsub wx-tropl" in the body of your message.
