.UPDATE...
WINDS OVER THE BIG ISLAND SUMMITS HAVE INCREASED TO ADVISORY
LEVELS DUE TO A TROUGH OF LOW PRESSURE PASSING BY NORTH OF THE
STATE. THUS A WIND ADVISORY HAS BEEN ISSUED THROUGH TONIGHT.

&&

.SYNOPSIS...
A VERY LARGE NORTHWEST SWELL WILL BEGIN TO ARRIVE LATE TODAY AND
PEAK THURSDAY. A SURFACE RIDGE NEAR THE ISLANDS WILL KEEP WINDS
LIGHT AND OUR WEATHER RATHER DRY THROUGH TODAY. A HIGH BUILDING
NORTH OF THE AREA ON THURSDAY WILL BRING A COUPLE OF DAYS OF
MODERATE TRADE WINDS. THE TRADES WILL PUSH SHOWERS FROM A COUPLE
OF OLD FRONTS OVER WINDWARD AREAS THROUGH THE WEEKEND. A NEW FRONT
WILL MOVE OVER THE ISLANDS EARLY NEXT WEEK.

&&

.PREV DISCUSSION.../ISSUED 427 AM HST WED FEB 24 2016/

AN EAST TO WEST SURFACE RIDGE REMAINS OVER US...BRINGING LIGHT
WINDS AND STABLE CONDITIONS. OVERNIGHT SOUNDINGS SHOWED STRONG
TEMPERATURE INVERSIONS NEAR 5200 FEET AT LIHUE AND 6800 FEET AT
HILO. STABLE LOW CLOUDS CONTINUE TO COVER SIGNIFICANT AREAS OF THE
ISLANDS...BUT RADAR SHOWS ONLY ISOLATED TO SCATTERED LIGHT
SHOWERS ARE OCCURRING...MAINLY OVER LOCAL WATERS AROUND OAHU AND
MOLOKAI. THE RIDGE WILL MAINTAIN LIGHT WINDS AND MOSTLY DRY
WEATHER THROUGH THIS EVENING.

A HIGH FAR NORTHWEST OF KAUAI WILL MOVE SOUTHEAST...PRECEDED BY A
SHEAR LINE. BY THIS EVENING THIS HIGH WILL BE ABOUT 600 MILES
NORTHWEST OF KAUAI AND TRADE WINDS DRIVEN BY THE HIGH ALONG THE
SHEAR LINE WILL SPREAD OVER THE ISLANDS. STARTING ON
THURSDAY...REMNANTS OF THE OLD FRONT THAT MOVED THROUGH THE
ISLANDS LAST WEEKEND WILL SPREAD BACK OVER THE BIG ISLAND AND MAUI
COUNTY AND REMNANTS OF THE SHEAR LINE WILL SPREAD OVER KAUAI.
SHOWERS WILL INCREASE...ESPECIALLY OVER WINDWARD AREAS...BUT THE
ATMOSPHERE WILL REMAIN TOO STABLE FOR EXCESSIVE RAINFALL.

DRIER WEATHER AND LIGHT WINDS WILL RETURN BY SUNDAY AS A RIDGE
REBUILDS OVER THE ISLANDS. ANOTHER FRONT MAY MOVE OVER THE ISLANDS
FROM THE NORTHWEST NEXT TUESDAY.

&&

AVIATION...
AN AREA OF LOW CLOUDS IS COVERING MOST OF THE HAWAIIAN ISLANDS THIS
HOUR WITH SOME EMBEDDED SHOWERS. THE PREVAILING CEILING WITH THE LOW
CLOUDS IS ABOVE MVFR CRITERIA...HOWEVER...BETWEEN 4 AND 6K FEET.
WE ANTICIPATE THESE CLOUDS AND SHOWERS WILL GRADUALLY DISSIPATE
DURING THE COURSE OF THE MORNING HOURS. DO EXPECT BRIEF MVFR
CEILINGS IN THESE SHOWERS. VIS MAY NOT BE AN ISSUE BASED ON THE
RADAR RETURNS WHICH ARE MAINLY LIGHT IN INTENSITY. NO AIRMETS ARE
CURRENTLY POSTED AND NONE ARE EXPECTED TO 04Z.

&&

.MARINE...
A HIGH SURF WARNING REMAINS UP AS FORERUNNERS FROM A NEW VERY
LARGE SWELL ARE FORECAST TO REACH KAUAI AS EARLY AS THIS MORNING.
THE NEW SWELL WILL BE FROM A MORE WESTERLY DIRECTION THAN THE
PREVIOUS ONE...AND IS LIKELY TO HAVE LESS IMPACT IN AREAS SUCH AS
THE WINDWARD SIDE OF THE BIG ISLAND BUT MIGHT PRODUCE BIGGER SURF
ALONG THE KONA SIDE. WE WILL LEAVE THE WARNING AND ADVISORY UP
FOR MOST AREAS SINCE THE NEW SWELL WILL BE ARRIVING SOON.

WINDS WILL REMAIN BELOW SMALL-CRAFT-ADVISORY...SCA...LEVELS
THROUGH TOMORROW NIGHT BUT A SCA WILL REMAIN UP DUE TO THE
ELEVATED SEAS AND A MARINE WEATHER STATEMENT WILL REMAIN UP
FOR MAUI AND THE BIG ISLAND.
