.SHORT TERM...
TONIGHT THROUGH FRIDAY NIGHT...SATELLITE IMAGERIES SHOW A SURFACE
TROUGH JUST NORTH OF THE ISLAND CHAIN. RAOB FROM THIS AFTERNOON
DEPICTS A STABLE PROFILE WITH NORTHERLY WINDS ALONG THE LOWER AND
MID LEVELS. MODELS SUGGEST THAT ISOLATED SHOWERS WILL PERSIST
THROUGHOUT THE SHORT TERM. HOWEVER...WITH LOWER TO MID LEVEL
NORTHERLY WINDS...THE SURFACE TROUGH TO THE NEAR NORTH WILL
DESCEND OR OSCILLATE OVER THE ISLANDS TONIGHT. TRADES HAVE BEEN
PERSISTENTLY BREEZY TODAY. MODELS HAVE INCREASED THE TRADES TO
STRONG CONDITIONS BY THURSDAY NIGHT. THEREFORE EXPECT SCATTERED
SHOWERS TONIGHT BEFORE DECREASING TO ISOLATED ON THURSDAY MORNING.

.LONG TERM...
SATURDAY THROUGH WEDNESDAY...MODELS AGREE THAT THE ACTIVE SURFACE
WILL PASS ACROSS THE ISLANDS ON SATURDAY NIGHT BEFORE DISSIPATING
ON MONDAY AFTERNOON. TRADES WILL PREVAIL THROUGHOUT THE LONG TERM.
THEREFORE NO CHANGES TO THE LONG TERM.

.MARINE...
SEAS OF 7 TO 9 FT WILL PERSIST TONIGHT BEFORE BUILDING 8 TO 10 FT
ON THURSDAY NIGHT. A HIGH PRESSURE APPROACHING FROM THE SOUTHWEST
WILL SLOWLY MIGRATE EAST AND ESCALATE TRADES AND SEAS ACROSS THE
ISLANDS. THEREFORE...HIGH SURF AND SMALL CRAFT ADVISORIES REMAIN
IN EFFECT.
