WHAT HAS CHANGED

All sections have been updated. The Coastal Flood Advisories were extended through this evening's high tide for all tidal areas. The Gale Warning was extended into the nearshore waters into tonight and shortened for the offshore waters.

KEY MESSAGES

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

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

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.

Persistent high pressure centered to the north will dominate the weather pattern leading to mainly dry conditions and coastal breezes. Generally near to below normal temperatures will likely become above normal late week, especially daytime highs.

AVIATION /12Z SUNDAY THROUGH THURSDAY/

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.

MARINE

Through Thursday...High pressure to the north will prevail through the period with low pressure far offshore tightening the pressure gradient. We have opted to extend the Gale Warning into the nearshore waters to cover for the marginal gale-force gusts into tonight. We also shortened the length of the Gale Warning for the offshore waters as it now appears gales should end later tonight instead of Monday. Mariners should note that the NE winds counter to the northward-flowing Gulf Stream waters will result in very steep/hazardous maritime conditions offshore for much of the period. Small Craft Advisory conditions will also likely linger across the nearshore waters much of the time from late tonight through mid week.
