| Area Forecast Discussion National Weather Service Newport/Morehead City NC 706pm EDT Tuesday Oct 27 2026 .WHAT HAS CHANGED... Cancelled the Small Craft Advisories with improving seas this afternoon. Issued new Small Craft Advisories starting Wednesday Morning. Increased rain chances along coastal communities Wednesday. .KEY MESSAGES... 1) Breezy NE winds and high astronomical tides will bring the potential for continued minor coastal flooding through at least mid week. 2) Mostly dry with climo temps through early this week, then warming to above climo mid to late week with continued dry conditions. Next chance of rain late weekend to early next week. Marine: Elevated seas may bring hazardous boating conditions Wednesday morning through Thursday. KEY MESSAGE 1...Strong high pressure building into the Mid-Atlantic and low pressure well off the FL coast will result in a period of continued long period swell across the OBX. The high waves combined with King Tides this week will lead to additional minor coastal flooding impacts. For Hatteras Island, seas offshore are in the 4-6 foot range this evening, but the long period swells will continue to cause issues for vulnerable areas. For ocean-side: high tide is around 0900pm EDT today. Soundside high tides lag by up 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. Minor coastal flooding of vulnerable locations will be likely well into this week despite the diminishing of winds, with "sunny day" flooding across much of the tidal regions of ENC around times of high tide, then slowly improve as the King Tides ease later in the week and into the weekend. Coastal flood advisories continue through the high tide cycle on Thursday. KEY MESSAGE 2...Dry high pressure with near climo temps expected today and tonight, then warming to above normal mid week through the weekend. A coastal trough offshore could bring isolated showers to coastal communities tomorrow into tomorrow night. PoPs have been increased to ~20% to account for this. Thunder chances remain below 5% along the coast tomorrow. Late week into the weekend, hts/thicknesses build further, and temps climbing back to 5-10 degrees above climo with highs around 80F inland to low 70s OBX. Low temps will warm above climo as well with readings in the mid 50s for most locales away from the immediate coast. Next chance of rain is Sunday. Marine High pressure ridging into the waters bringing N/NE winds 10-15 kts, and elevated seas are only slowly subsiding due to the long period nature of the swells. With a ~18 hours period of seas below 6 ft, elected to drop the previous SCA, and issue a new SCA (Small Craft Advisory) starting at 12Z Wednesday, continuing through Thursday. Outlook (Wednesday through Sat):Early Wednesday morning renewed nerly pressure gradient redevelops with SCA (Small Craft Advisory) seas and/or winds. The winds and seas finally diminish by early Thu north of Ocracoke, and by Thu evening for remaining southern coastal waters. High building in late week brings pleasant boating conditions to the region. NOAA Newport/Morehead City NC Office - Watches - Warnings - Advisories NC...Coastal Flood Advisory until 2pm EDT Thursday for NCZ195-196- 199-203>205. Beach Hazards Statement until 8pm EDT this evening for NCZ196- 203>205. Marine Small Craft Advisory from 8am Wednesday to 8pm EDT Thursday for AMZ152(Oregon Inlet to Cape Hatteras NC)-154-156-158. |
