Discussion

KEY MESSAGE 1...Minor coastal flooding and hazardous marine/surf conditions are expected at least into mid week.

An extended period of enhanced northeast winds due to strong high pressure to the north and low pressure well to the southeast will continue to bring hazardous marine/surf conditions across the NE SC and SE NC coasts and nearby Atlantic waters. Also, high astronomical tides and onshore winds will lead to minor coastal flooding.

Coastal Flooding: Minor coastal flooding is likely during each high tide cycle through at least Tue AM, with the highest tides in the morning.

High Surf: High seas up near 10 ft within 20 nm will likely lead to 6 ft surf heights early this week, especially along the beaches of New Hanover County. In addition, the large waves coupled with high water levels could result in some erosion, especially for E-facing beaches.

Marine: See the Marine section below for details regarding marine hazards.

KEY MESSAGE 2...High pressure will prevail through the week bringing generally dry weather and coastal breezes.

Aviation

High confidence in VFR conditions as high pressure prevails. Very low risk of MVFR/IFR CIGs and LLWS this morning. NNE/NE winds will prevail, gusting to near 20-25 kt at times.

VFR to prevail with gusty NE winds expected at times, especially near the coast. There is a low risk for CIG restrictions, mainly during late night/early morning periods.
