AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE NEWPORT/MOREHEAD CITY NC
739 PM EDT MON MAR 10 2025
SYNOPSIS
A WAVE OF LOW PRESSURE WILL RIDE ALONG THE STALLED FRONT
PASSING SOUTH OF THE AREA TODAY INTO TUESDAY BRINGING UNSETTLED
WEATHER AND GUSTY WINDS TO PARTS THE AREA. HIGH PRESSURE THEN
BUILDS IN FROM THE WEST ON TUESDAY AND WEDNESDAY RESULTING IN
FAIR WEATHER AND A WARMING TREND WHICH SHOULD CONTINUE INTO NEXT
WEEKEND.
NEAR TERM /UNTIL 6 AM TUESDAY MORNING/
AS OF 7 PM MON...
KEY MESSAGES:
- WIND ADVISORY IN EFFECT FOR EAST CARTERET, OCRACOKE ISLAND,
AND HATTERAS ISLAND
- STRENGTHENING LOW PRESSURE SYSTEM MAKES ITS CLOSEST POINT OF
APPROACH. STRONG NORTHEAST TO NORTHERLY WINDS OVERSPREAD
COASTAL ENC TONIGHT. MINOR COASTAL IMPACTS EXPECTED.
- STRONG WINDS AND LARGE SEAS MAY BRING MINOR COASTAL FLOODING IMPACTS
TO SOME BEACHES, SEE THE COASTAL FLOODING SECTION BELOW FOR
MORE DETAILS.
A SURFACE LOW NOW LOCATED ALONG THE NC COAST JUST SOUTH OF CAPE
FEAR WILL CONTINUE TO DEEPEN THIS EVENING AS IT MOVES EASTWARD
AND OUT OVER ONSLOW BAY. AHEAD OF THIS LOW, STRONG CONVECTIVE
FEATURES HAVE EMERGED, AND THIS ACTIVITY WILL LIKELY TRACK ALONG
THE SOUTHERN NC COAST EAST TO CAPE LOOKOUT, AND HAVE INCREASED
POPS IN THIS AREA TONIGHT AND ADDED IN CHANCES FOR THUNDER. A
NON-ZERO BUT SMALL SEVERE THREAT WILL EXIST IN THIS SECTOR IF
CONVECTION REMAINS AS ORGANIZED AS IT IS NOW OVER CAPE FEAR.
ELSEWHERE, MODERATE TO LIGHT RAIN WILL SPREAD BACK IN FOR SOME
TIME TONIGHT, BEFORE DRIER AIR BEGINS TO WORK IN FROM THE WEST
AS THE LOW MOVES EAST OF CAPE LOOKOUT. RAIN CHANCES ALONG THE
COAST AND OBX WILL CONTINUE FOR MOST OF THE NIGHT, DECREASING
TOWARDS DAYBREAK.
AS LOW APPROACHES ENC THIS EVENING, NORTHEAST WINDS WILL
CONTINUE TO STRENGTHEN AND BECOME MORE NORTHERLY AS THE PRESSURE
GRADIENT TIGHTENS WITH WINDS OF 20-30+ KTS (GUSTS TO 45 KTS)
POSSIBLE ACROSS AREA WATERS AND ALONG THE OUTER BANKS. HAVE
ISSUED A WIND ADVISORY FOR EAST CARTERET, OCRACOKE ISLAND, AND
HATTERAS ISLAND WITH AFTERNOON PACKAGE. WINDS WILL BE WEAKER
INLAND (10-15 KTS WITH GUSTS TO 20 KTS).
FOR TEMPERATURES, CLOUD COVER WILL INITIALLY LIMIT COOLING
TONIGHT, BUT SKIES BEGIN TO CLEAR FROM WEST-TO- EAST LATE. THIS
CLEARING COUPLED WITH WEAK COLD ADVECTION AFTER THE LOW PASSES
WILL CONTRIBUTE TO LOWS FALLING TO THE LOW 40S INLAND WHILE
TEMPS REMAIN IN THE LOW 50S ALONG THE COAST.
SHORT TERM /6 AM TUESDAY MORNING THROUGH 6 PM TUESDAY/
AS OF 330 PM MON...
COASTAL LOW WILL BE QUICKLY PROGRESSING OVER THE OPEN
ATLANTIC BY SUNRISE WITH ONLY A SLIGHT CHANCE OF SPOTTY REMNANT
SHOWERS OVER THE OUTER BANKS TO START THE DAY. OTHERWISE, MID-
LEVEL HEIGHT RISES AND RAPID ADVECTION OF DRY AIR WILL AID IN
SKIES QUICKLY CLEARING. TEMPS EXPECTED TO WARM INTO THE LOW 70S
INLAND, BUT NORTHERLY WINDS KEEP OBX CLOSER TO THE UPPER 50S TO
LOW 60S.
LONG TERM /TUESDAY NIGHT THROUGH MONDAY/
AS OF 330 PM MON...QUIET WEATHER RETURNS TO EASTERN NC FOR THE
EXTENDED PERIOD AS TODAY'S COASTAL LOW PUSHES OFFSHORE AND HIGH
PRESSURE BECOMES THE DOMINANT WEATHER DRIVER FOR THE REST OF THE
WORK WEEK. ATTENTION REMAINS ON A STRONGER COLD FRONT EXPECTED
TO IMPACT MUCH OF THE EASTERN CONUS OVER THE WEEKEND, REACHING
OUR AREA BY SUNDAY.
WEDNESDAY THROUGH SATURDAY..FLAT RIDGING ALOFT AND SFC HIGH
PRESSURE BUILD INTO THE AREA WEDNESDAY FOLLOWED BY A FAST MOVING
SHORTWAVE MOVING ACROSS THE AREA THURSDAY. MOISTURE WILL BE
LIMITED BY THE TIME THE WAVE REACHES EASTERN NC AND EXPECT ONLY
AN INCREASE IN CLOUDS, BUT WOULD NOT BE SURPRISED TO SEE
SHOWERS DEVELOPING ALONG THE OFFSHORE COASTAL TROUGH WHICH MAY
THREATEN COASTAL LOCALES. FOR NOW, KEPT POPS CONFINED OFFSHORE.
UPPER RIDGING BUILDS BACK INTO THE AREA FRIDAY, THEN SLIDES
OFFSHORE SATURDAY AS A STRONG UPPER TROUGH AND ATTENDANT FRONTAL
SYSTEM PUSHES INTO THE TENNESSEE RIVER VALLEY. MODEL AGREEMENT
ON THIS FEATURE IS QUITE GOOD FOR A DAY 6-7 FORECAST, AND
CONTINUED LIKELY POPS FOCUSED ON SUNDAY. GIVEN THE STRENGTH OF
THE FRONT, WINDS AHEAD OF THE BOUNDARY WILL BE QUITE BREEZY,
RAISING THE POSSIBILITY OF ANOTHER ROUND OF COASTAL/FLOODING
AND ROUGH SURF ALONG THE OUTER BANKS. LESS CERTAIN IS
THUNDERSTORM AND SEVERE POTENTIAL, ALTHOUGH TEMPS WILL BE HIGH
ENOUGH, AND MOISTURE PLENTIFUL ENOUGH TO GET AT LEAST MODEST
INSTABILITY. AS USUAL, DETAILS WILL COME INTO BETTER FOCUS WITH
FUTURE FORECASTS AND WE ENCOURAGE USERS TO STAY TUNED.
AVIATION /23Z MONDAY THROUGH SATURDAY/
SHORT TERM /THROUGH TUESDAY EVENING/...
AS OF 7 PM MON...SUB-VFR CONDITIONS WILL CONTINUE ACROSS MOST OF
EASTERN NC SOUTH OF US 264, WHILE AREAS NORTH REMAIN VFR THROUGH
THE PERIOD AS LOW PRESSURE PASSES BY JUST SOUTH OF CAPE LOOKOUT.
RAIN SHOWERS AND SCATTERED THUNDERSTORMS ARE FILLING BACK INTO
THE AREA AS LOW PRESSURE DEEPENS JUST OFF OF CAPE FEAR THIS
EVENING. MVFR CONDITIONS WILL CONTINUE TONIGHT ACROSS THE
SOUTHERN COAST AND EAST TO THE SOUTHERN OBX, INCLUDING AS FAR
NORTH AS KOAJ AND KEWN. HERE CEILINGS WILL LIKELY LOWER TO
100-1500 FT IN THE NEXT FEW HOURS AS THE HEAVIEST RAIN MOVES
THROUGH, AND SOME BRIEF IFR CONDITIONS MAY DEVELOP AS WELL.
FARTHER NORTH, BUT SOUTH OF US 264, VFR CONDITIONS ARE PRESENT
RIGHT NOW, BUT A FEW HOUR PERIOD OF MVFR CEILINGS IS EXPECTED
TO DEVELOP AS STEADIER RAIN MOVES IN THIS EVENING.
AFTER MIDNIGHT, CONDITIONS WILL BEGIN TO IMPROVE WITH CEILINGS
SLOWLY LIFTING, HOWEVER MVFR CONDITIONS WILL CONTINUE ALONG THE
COAST (INCLUDING KEWN AND KOAJ) THROUGH AT LEAST 3-5 AM.
THEREAFTER, VFR CONDITIONS WILL RETURN FOR THE REST OF TOMORROW
WITH SKIES CLEARING BEFORE MID MORNING.
LONG TERM /TUESDAY NIGHT THROUGH SATURDAY/...
AS OF 330 PM MON...WINDS VEER TO THE NORTH TUESDAY WITH GUSTS
TO AROUND 15-20 KT INLAND AND 25-35 KT ALONG THE COAST WITH
CLEARING SKIES AND A RETURN TO VFR CONDITIONS AS THE LOW PULLS
AWAY FROM THE AREA. PREDOMINANTLY VFR PREVAILS THROUGH FRIDAY,
WITH AN INCREASE IN CLOUD COVER THURSDAY WITH A PASSING MID-
LEVEL WAVE.
MARINE
SHORT TERM /THROUGH MONDAY NIGHT/...
AS OF 330 PM MON...
KEY MESSAGES:
- STRENGTHENING LOW IMPACTS THE REGION THIS EVENING AND TONIGHT
BRINGING HAZARDOUS MARINE CONDITIONS TO AREA WATERS.
- STRONG WINDS AND LARGE SEAS MAY BRING MINOR COASTAL FLOODING
IMPACTS TO SOME BEACHES, SEE THE COASTAL FLOODING SECTION BELOW
FOR MORE DETAILS.
1005 MB SURFACE LOW CURRENTLY ANALYZED ALONG THE GA/SC
COASTLINE WILL CONTINUE TO DEEPEN AS IS APPROACHES ENC THIS
AFTERNOON AND EVENING. NORTHEASTERLY WINDS AHEAD OF THIS SYSTEM
HAVE INCREASED TO 10-15 KNOTS (GUSTS TO AROUND 20 KNOTS NOTED
ALONG PORTIONS OF THE OUTER BANKS). IN ADDITION TO THIS,
SEAS SOUTH OF OREGON INLET HAVE INCREASED TO 3-6 FT. LOW WILL
MAKE ITS CLOSEST POINT OF APPROACH TO ENC TONIGHT. NORTHEAST
WINDS WILL CONTINUE TO INCREASE, PEAKING AT 25-35 KT OVER THE
SOUTHERN AND CENTRAL COASTAL WATERS AND 15-25 KT ACROSS THE
PAMLICO SOUND, INLAND RIVERS, AND OUTER WATERS NORTH OF OREGON
INLET. AS THE LOW NEARS OUR COAST AND BEGINS TO PUSH OUT TO SEA
LATE TONIGHT, WINDS WILL GRADUALLY SHIFT TO MORE NORTHERLY WHILE
STRENGTHENING FURTHER WITH 25-30 KT NE-N WINDS WITH 35 KT GUSTS
POSSIBLE ACROSS THE PAMLICO SOUND AND 25-35 KT NE-N WINDS AND
40-45 KT GUSTS ACROSS THE COASTAL WATERS SOUTH OF OREGON INLET
TONIGHT. SEAS WILL RESPOND IN KIND TO THE STRONG WINDS
INCREASING TO 6-9 FT SOUTH OF OREGON INLET THIS AFTERNOON
EVENTUALLY GETTING TO 8-12 FT BY TONIGHT. ACROSS OUR FAR
NORTHERN WATERS SEAS WILL CONTINUE TO BUILD TO 4-6 FT THIS
EVENING AND THEN 6-8 FT BY TUE MORNING. THESE HAZARDOUS MARINE
CONDITIONS CONTINUE INTO EARLY TUE MORNING BEFORE GRADUALLY
BEGINNING TO EASE AS THE LOW PULLS AWAY FROM THE COAST.
LONG TERM /TONIGHT THROUGH SATURDAY/...
AS OF 330 PM MON... SEAS PEAK TUESDAY MORNING AROUND 8-12 FT
SOUTHERN AND CENTRAL WATERS AND 5-8 FT ACROSS THE NORTHERN
WATERS, THEN BEGIN TO SUBSIDE TUESDAY AFTERNOON AND EVENING.
HIGH PRESSURE BUILDS IN WEDNESDAY BRINGING LIGHT WINDS WITH SEAS
CONTINUING TO SUBSIDE TO 3-5 FT BY LATE IN THE DAY. THE HIGH
MOVES OFFSHORE THURSDAY BRINGING SOUTHERLY WINDS AROUND 10-15 KT
WITH SEAS AROUND 2-4 FT.
MARINE INTERESTS SHOULD MONITOR FORECASTS FOR THE WEEKEND AS A
STRONG COLD FRONT IS LIKELY TO APPROACH AREA WATERS, RAISING THE
RISK FOR WIDESPREAD GALES AND DANGEROUS OFFSHORE CONDITIONS.
TIDES/COASTAL FLOODING
AS OF 330 PM MON...STRENGTHENING LOW PRESSURE SYSTEM WILL MAKE
ITS CLOSEST APPROACH TO ENC TONIGHT BEFORE PUSHING FARTHER OFF
THE COAST TOMORROW. NORTHEASTERLY WINDS CONTINUE TO INCREASE
INTO THE OVERNIGHT HOURS AS THE LOW DEEPENS. WINDS THEN PEAK
OUT OF THE NORTH-NORTHEAST TONIGHT, BECOMING NORTH AND
GRADUALLY DIMINISHING TUESDAY AS THE LOW PUSHES FARTHER OFFSHORE.
THE STRONGEST WINDS WILL BE FOCUSED OVER THE COASTAL WATERS
SOUTH OF CAPE HATTERAS WHERE GALE FORCE WINDS ARE EXPECTED.
HIGH SURF ADVISORY HAS BEEN ISSUED FROM SOUTH OF OREGON INLET TO
CAPE HATTERAS WHERE THE COMBINATION OF ONSHORE WINDS AND
BREAKING WAVES AROUND 5-8 FT COULD PRODUCE MINOR BEACH AND DUNE
EROSION AND POSSIBLY MINOR OCEAN OVERWASH AT VULNERABLE
LOCATIONS. HAVE ISSUED A COASTAL FLOOD ADVISORY FOR THE
POTENTIAL FOR LOCALIZED OCEAN OVERWASH IN THE SAME LOCATIONS
WITH POTENTIAL INUNDATION OF 1-2 FEET ABOVE GROUND LEVEL.
STRONGER WINDS WILL ALSO BE FOCUSED SOUNDSIDE, ESPECIALLY ACROSS
THE SOUTHERN HALF OF THE PAMLICO SOUND. MINOR SOUNDSIDE WATER
LEVEL RISES IS POSSIBLE FOR AREAS ADJACENT TO THE SOUTHERN
PAMLICO SOUND, NEUSE AND BAY RIVERS, AND LESS SO FOR THE PAMLICO
AND PUNGO RIVERS. GIVEN A SLIGHT UPTICK IN SOUNDSIDE FORECAST
WINDS AND SUPPORT FROM RELIABLE GUIDANCE, DECIDED TO ISSUE A
COASTAL FLOOD ADVISORY FOR PAMLICO, S CRAVEN AND E CARTERET FOR
1-2 FEET OF INUNDATION ABOVE GROUND LEVEL.
