AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE NEWPORT/MOREHEAD CITY NC
345 PM EDT SUN OCT 25 2026
WHAT HAS CHANGED
MARINE HEADLINES ADJUSTED BASED ON OBS AND FORECAST. COASTAL
FLOOD ADVISORIES HAVE BEEN EXPANDED TO INCLUDE BEAUFORT COUNTY
AND HAVE BEEN EXTENDED ANOTHER 24H. AVIATION DISCO UPDATED.
KEY MESSAGES
1) BREEZY NE WINDS AND HIGH ASTRONOMICAL TIDES WILL BRING THE
POTENTIAL FOR ADDITIONAL COASTAL IMPACTS THROUGH AT LEAST MID
WEEK.
2) MOSTLY DRY WITH NEAR TO SLIGHTLY BELOW CLIMO TEMPS THROUGH
THE WEEKEND AND EARLY NEXT WEEK, THEN WARMING TO ABOVE CLIMO MID
TO LATE WEEK WITH CONTINUED DRY CONDITIONS.
MARINE: GUSTY NORTHEAST WINDS AND LARGE SEAS WILL CONTINUE TO
BRING HAZARDOUS BOATING CONDITIONS THIS WEEKEND AND CONTINUING
THROUGH MUCH OF THE UPCOMING WEEK.
DISCUSSION
KEY MESSAGE 1...STRONG HIGH PRESSURE BUILDING INTO THE MID-ATLANTIC
AND LOW PRESSURE WELL OFF THE SE COAST WILL RESULT IN A PERIOD OF
BREEZY TO STRONG NE WINDS THROUGH EARLY THIS WEEK WITH
STRONGEST WINDS ALONG THE COAST, ESPECIALLY SOUTH OF CAPE
HATTERAS WHERE GRADIENTS WILL BE TIGHTEST. THIS, COMBINED WITH
UPCOMING KING TIDE CYCLE LEAD TO ADDITIONAL MINOR COASTAL
IMPACTS (COASTAL FLOODING AND ROUGH SURF).
FOR HATTERAS ISLAND, SEAS OFFSHORE CONTINUE IN THE 7-9 FOOT
RANGE AND WILL REMAIN IN THIS RANGE TODAY, AND THEN SLOWLY
SUBSIDE THROUGH THE COMING WEEK, BUT LONG PERIOD SWELLS WILL
CONTINUE TO CAUSE ISSUES FOR VULNERABLE AREAS IN CONJUNCTION
WITH THE BUILDING KING TIDES. FOR OCEAN-SIDE: HIGH TIDE IS
ARE 1930EDT TONIGHT AND BETWEEN 0730-0800EDT MON. SOUNDSIDE
HIGH TIDES LAG FROM 2 TO 3 HOURS BEHIND THE OCEANSIDE TIDES. THE
NATIONAL PARKS SERVICE AND NCDOT HAVE REPORTED SUBSTANTIAL
BEACH EROSION FROM SOUTH NAGS HEAD TO BUXTON, ALONG WITH
SIGNIFICANT OVERWASH OCCURRING ON SIDE STREETS IN RODANTHE. DUE
TO HAZARDOUS ROAD CONDITIONS AND FLOODING, NC-12 REMAINS CLOSED
FROM THE MARC BASNIGHT BRIDGE TO RODANTHE.
COASTAL FLOODING WILL BE LIKELY WELL INTO THIS WEEK. EVEN WITH
WINDS DIMINISHING BY MID WEEK, "SUNNY DAY" COASTAL FLOODING
ACROSS MUCH OF THE TIDAL REGIONS OF ENC AROUND TIMES OF HIGH
TIDE WILL CONTINUE THROUGH AT LEAST MID WEEK, THEN SLOWLY
IMPROVE AS THE KING TIDES EASE LATER IN THE WEEK. THE AREAS
MOST SUSCEPTIBLE TO STREET FLOODING WILL BE LOW LYING AREAS
ALONG THE NEUSE AND BAY RIVERS AS WELL AS DOWNEAST CARTERET
COUNTY TO NORTH TOPSAIL BEACH WHICH HAS ALREADY BEEN SEEN DURING
THE LAST TWO MORNING'S HIGH TIDES. SOME FLOODING OCCURED WITH
THIS MORNING'S HIGH TIDE IN BEAUFORT COUNTY, SO HAVE ADDED THEM
TO THE ADVISORIES WITH WATER LEVELS ONLY GETTING HIGHER THROUGH
MIDWEEK.
THERE IS STILL POTENTIAL THAT THE HEADLINES FOR TUE AND WED MAY
NEED TO BE UPGRADED TO COASTAL FLOOD WARNINGS. WILL WAIT FOR
THIS DECISION AFTER WE SEE WHAT MON MORNING'S HIGH TIDE BRINGS.
IN ADDITION, IF SEAS INCREASE ANY FURTHER THAN CURRENTLY
FORECAST, A PERIOD OF COASTAL FLOOD WARNINGS MAY BE NEEDED FOR
PARTS OF THE OBX, AND WILL NEED TO MONITOR TRENDS.
KEY MESSAGE 2...POCKETS OF MOISTURE CONTINUE TO BE SQUEEZED
BETWEEN THE INLAND HIGH AND OFFSHORE LOW, THOUGH ALMOST ALL
GUIDANCE KEEPS THE BULK OF PRECIP ACTIVITY OFF THE COAST AND
PERHAPS SKIRTING OBX. MOST AREAS REMAIN DRY TODAY, ALONG WITH
SEASONABLY COOL TEMPS IN THE LOW 70S INTERIOR TO 60S COAST.
PLEASANTLY COOLER AND DRIER AIR MASS WILL REMAIN WITH US THROUGH
EARLY THIS WEEK, WITH NEAR CLIMO HIGHS, TO SLIGHTLY BELOW AVG
LOWS, ESP SUN AND MON NIGHTS WHEN GOOD RADIATIONAL COOLING YET
AGAIN SETS UP WITH LOWS WELL DOWN INTO THE 40S WITH SOME 30S
AGAIN POSSIBLE TUE MORNING WHEN THE HIGH PRESSURE CENTER IS
CLOSER TO ENC ALLOWING NOCTURNAL WINDS TO FALL OFF HARDER AND
SKIES TO CLEAR MORE THAN THE LAST FEW NIGHTS. HTS/THICKNESSES
THEN BEGIN TO BUILD BY MID WEEK, WITH TEMPS CLIMBING BACK ABOVE
CLIMO WITH HIGHS IN THE MID 70S, THEN UPPER 70S BY WEEKS END.
LOWS WILL REMAIN CLOSER TO CLIMO AS DRY AIRMASS REMAINS WITH A
LARGE DIURNAL TEMP RANGE.
AVIATION /18Z SUNDAY THROUGH FRIDAY/
VFR CONDITIONS CONT ACROSS ENC OVER THE NEXT 24 HOURS. DIURNAL
CU AOA FL040 SO NO SIGNIFICANT IMPACT TO OPERATIONS IS FORECAST
TODAY. NE WINDS 10-15 KT WITH GUSTS UP NEAR 20 KTS DURING THE
DAYTIME MIXING PERIOD, 30KT OVER THE IMMEDIATE COAST (MRH),
THEN BECOMING LIGHT AGAIN BY THIS EVENING. FEWER CLOUDS AND
SLIGHTLY WEAKER WINDS EXPECTED FOR MON AS HIGH NEARS THE FA.
OUTLOOK (MONDAY THROUGH THURSDAY): GENERALLY, EXPECT VFR
CONDITIONS TO CONTINUE THROUGH THE NEXT SEVERAL DAYS WITH STRONG
HIGH PRESSURE BUILDING IN FROM THE NORTH. HOWEVER, COASTAL
SECTIONS COULD SEE MVFR STCU AT TIMES. WINDS BECOME CALM MON
NIGHT/EARLY TUE AS STRONG INVERSION DEVELOPS WITH HIGH PRES
OVERHEAD WITH SKC AND CALM WINDS, OPENING POTENTIAL FOR
IMPACTFUL FOG TO DEVELOP.
MARINE
HIGH PRESSURE BUILDING IN FROM THE NORTH WILL ACT TO TIGHTEN
THE PRESSURE GRADIENT ACROSS THE REGION WITH NE WINDS 15-20 KT
WITH GUST CONT 25-30 KT, 35-40KT GUSTS OVER COASTAL AND OFFSHORE
WATERS S OF CAPE LOOKOUT. LESSER CHANCES FOR GUSTY SCA WINDS
FOR ALLIGATOR/ALBEMARLE AS WIND FCST HAS EASED HERE, BUT
REMAINING NEARSHORE WATERS INCLUDING PAMLICO AND NEUSE REMAIN
WITH SCA CONDITIONS. WINDS DECREASE LATER TONIGHT AND MON WITH
APPROACHING HIGH PRES, ALLOWING FOR MARINE HEADLINES TO BEGIN
STEPPING DOWN A FEW HOURS AFTER SUNSET TONIGHT.
OUTLOOK (MON THROUGH THU): HIGH PRES WILL BUILD IN EARLY TO MID
WEEK WITH WINDS DIMINISHING SIGNIFICANTLY, THOUGH SEAS WILL BE
SLOW TO SUBSIDE, AND LONGER PERIOD HIGH SWELLS APPEAR TO CONT AS
ADVECTED 6+ FT SWELLS AFFECT ESP THE SOUTHERN/CTRL WATERS SOUTH
OF OREGON INLET THROUGH MID/LATE WEEK.
