200 FXUS62 KMHX 220730 AFDMHX Area Forecast Discussion National Weather Service Newport/Morehead City NC 330 AM EDT Fri Aug 22 2025 .SYNOPSIS... Hurricane Erin is forecast to lift further out to sea today, although significant coastal impacts will continue across parts of the Outer Banks. High pressure builds in through early in the weekend. A weak coastal low may bring light rain on Sunday, with high pressure reestablishing itself next week. && .NEAR TERM /THROUGH TODAY/... As of 1:30 AM Friday... Key Messages: - Signifcant coastal impacts from Hurricane Erin will continue today, especially along the Outer Banks - Dry, slightly cooler, and less humid High pressure will build into the area today as Hurricane Erin continues to depart to the northeast. Winds will remain out of the north/northeast today and steadily ease as the pressure gradient relaxes. This flow will advect cooler and drier air into the area, resulting in cooler temps in the low- to mid-80s and, more notably, dewpoints falling to the mid- to upper-60s. Although Hurricane Erin will get progressively farther from our coast today, continued elevated water levels from strong winds, higher than normal astronomical tides, lingering powerful swell energy and wave run up, and compromised dune structures will prolong significant coastal impacts, especially along Outer Banks Dare County. Additional coastal impacts are expected farther south as well (see the TIDES/COASTAL FLOOD section for details). && .SHORT TERM /TONIGHT/... As of 2 AM Friday...A quiet night is in store with high pressure still in control. Winds will be light out of the northeast with lows ranging from the low-60s across northwestern zones to near 70 along the coast. && .LONG TERM /SATURDAY THROUGH THURSDAY/... As of 3 AM Fri... Saturday...Lingering coastal impacts on parts of the OBX will continues due large backswell from Erin. Sensible weather impacts improve as high builds in. Mainly dry wx and seasonably warm temps expected as the high remains through the end of the week. Sunday...Weak low pres may zip up the Southeastern Seaboard the end of the weekend, bringing some rain to the coast. Best chances for rain are the coastal counties, where pops are in the 50-70% range, with much lesser chances inland, and pops remain in the 30-40% range. Monday through Thursday...High pres reestablishes itself by early next week, and therefore pops no higher than 10-20% are forecast. Seasonably mild temps in the fcst with highs in the 80s and lows 65-70 forecast, which is very near climo for the last week of August. && .AVIATION /07Z FRIDAY THROUGH TUESDAY/... SHORT TERM /through tonight/... As of 1:15 AM Friday...A shield of MVFR stratus is overpsreading the area with southwest zones being the last to hang on to VFR SKC. Confidence in the overnight TAF forecast is lower than normal as guidance has been playing catch up in terms of coverage and height of the ongoing stratus. If the trend remains the same as the past few nights, MVFR stratus will hang on until after sunrise before scattering out. Conditions will be closely monitored and amended as needed. With high pressure building across the area today, VFR flight conditions are expected through the remainder of the period with fair weather cu and light NNE winds. LONG TERM /Sat through Tue/... As of 3 AM Fri...Mainly dry weather cont on Sat, though light rain chances for Sun could bring periods of sub VFR esp to the coastal areas. High pres returns as the work week begins. && .MARINE... SHORT TERM /through tonight/... As of 2:20 AM Friday...Hurricane Erin will continue to pull away to the northeast today, which will relax the pressure gradient and ease the winds. Although seas will start to ease as well, powerful back swell will continue through the period. Northerly winds will gradually veer to the northeast today and decrease from 15-25 kt this morning to 10-15 kt by early Saturday. Seas are currently 10-15 ft at 13-14 seconds north of Ocracoke Inlet (highest off Oregon Inlet) and 5-10 ft at 10-13 seconds to the south. By early Saturday morning, seas are forecast to decrease to 5-10 ft north of Ocracoke Inlet and 4-7 ft to the south. Therefore, SCAs will continue for all coastal waters through the period. LONG TERM /Sat through Tuesday/... As of 3 AM Fri...Light winds for the weekend into early next week, though lingering long period 6+ ft swell will linger from departing Erin. && .TIDES/COASTAL FLOODING... As of 3 AM Fri... Key Messages: - Significant impacts from Hurricane Erin are likely to continue across Outer Banks Dare County south of Oregon Inlet through this evening`s high tide cycle due to the following factors: 1)continued elevated water levels from strong winds 2) higher than normal astronomical tides 3) lingering powerful swell energy and wave run up 4) compromised dune structures from repeated inundation. Water level rises of 2-3 ft AGL (above ground level) are possible with locally higher amounts. - Storm Surge Warnings have been transitioned to Coastal Flood Warnings, and elsewhere Surge/Coastal Flood Warnings have been transitioned to Coastal Flood Advisories where nuisance flooding may impact some properties, with limited to no travel impacts anticipated. - Life threatening rip currents are expected to cont into the weekend, esp on the OBX. && .MHX WATCHES/WARNINGS/ADVISORIES...
