AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE HONOLULU HI
308 PM HST TUE MAR 4 2025
SYNOPSIS
BREEZY TO STRONG TRADES WILL CONTINUE THROUGH THE FORECAST PERIOD
BRINGING A RETURN TO A TYPICAL DISTRIBUTION OF CLOUDS AND SHOWERS
FOCUSED MAINLY OVER WINDWARD AND MAUKA AREAS.
DISCUSSION
WINDS AT PRESS TIME THIS AFTERNOON REMAIN QUITE GUSTY, IF
GENERALLY JUST BELOW THE ADVISORY THRESHOLD. EXPECT THIS EVENING
AND TONIGHT TO EVOLVE IN SIMILAR FASHION TO LAST NIGHT WITH GUSTY
WINDS RETREATING TO ONLY THE MOST FAVORABLE LOCALES BEFORE
EXPANDING IN COVERAGE ONCE AGAIN DURING WEDNESDAY. THE ISLANDS
REMAIN UNDER THE INFLUENCE OF MID-LEVEL RIDGING AND STABLE
ANTICYCLONIC FLOW AT THE SURFACE FOR THE REMAINDER OF THE FORECAST
PERIOD WITH NOTHING MORE THAN OCCASIONAL FLUCTUATIONS IN
INTENSITY AS THE MID-LATITUDE STORM TRACK REMAINS PROGRESSIVE AND
OCCASIONALLY TAMPS DOWN RIDGING IN THE LOWER LATITUDES OF THE
CENTRAL PACIFIC. THIS WILL IN TURN SUPPORT MEAN HIGH PRESSURE
LOCALLY WITH AREAS OF STRONG HIGH PRESSURE PERIODICALLY BUILDING
NORTH OF THE AREA THAT WILL STRENGTHEN TRADES, AS IS THE CASE
TODAY. THEREFORE, EXPECT BREEZY TO STRONG TRADES FOR THE BALANCE
OF THE FORECAST PERIOD WITH A TYPICAL DISTRIBUTION OF CLOUDS AND
SHOWERS WINDWARD AND MAUKA. AN UPTICK IN SHOWER COVERAGE IS
EXPECTED DURING THE LATTER HALF OF THE WEEK AS REMNANT FRONTAL
MOISTURE PIVOTS THROUGH THE FORECAST AREA.
AVIATION
STRONG SURFACE HIGH PRESSURE NORTH OF THE STATE WILL GRADUALLY
PROGRESS EASTWARD OVER THE NEXT SEVERAL DAYS AND BRING BREEZY TO
LOCALLY STRONG TRADE WINDS TO THE MAIN HAWAIIAN ISLANDS. PERIODS
OF CLOUDS AND SHOWERS WILL FAVOR WINDWARD AND MAUKA AREAS,
PARTICULARLY DURING THE OVERNIGHT TO EARLY MORNING HOURS. BRIEF
MVFR CEILINGS AND VISIBILITY WILL BE POSSIBLE IN SHOWERS.
OTHERWISE, VFR CONDITIONS WILL PREVAIL.
AIRMET TANGO IS IN EFFECT FOR LOW-LEVEL TURBULENCE BELOW 8000
FEET OVER AND DOWNSTREAM OF ISLAND TERRAIN DUE TO THE BREEZY TO
LOCALLY STRONG TRADE WINDS. THIS AIRMET WILL LIKELY BE EXTENDED
THROUGH THE NEXT SEVERAL DAYS AS THE TRADES REMAIN ELEVATED.
MARINE
STRONG TO NEAR-GALE EASTERLY TRADES PERSIST THROUGH THE WEEK AS
STRONG HIGH PRESSURE REMAINS N OF THE AREA. SEAS REMAIN ROUGH DUE
TO A COMBINATION OF SHORT PERIOD E FRESH SWELL AND NW SWELLS
MOVING THROUGH. THE SMALL CRAFT ADVISORY CONTINUES FOR ALL
HAWAIIAN WATERS AND WILL LIKELY REMAIN IN EFFECT FOR MOST OR ALL
WATERS THROUGH THE WEEK.
SURF ALONG EXPOSED N AND W FACING SHORES IS STEADILY EASING AS THE
PRESENT NW (310-320) SWELL SUBSIDES THROUGH MIDWEEK. AN UPWARD
TREND IS EXPECTED THURSDAY NIGHT THROUGH SATURDAY AS A COUPLE OF
NW (320-330) SWELLS ARRIVE AND PEAK FRIDAY NIGHT THROUGH
SATURDAY. THIS MAY PUSH SURF BACK TO ADVISORY LEVELS. A DOWNWARD
TREND IS THEN EXPECTED SUNDAY THROUGH EARLY NEXT WEEK. SURF ALONG
E EXPOSURESREMAINS ROUGH THROUGH THE WEEK DUE TO STRONG EASTERLY
TRADES. SURF ALONG S SHORES REMAINS SMALL, WITH MAINLY BACKGROUND
S AND SE SWELLS.
