WHAT HAS CHANGED

The Aviation Section has been updated for the 12Z TAF issuance.

KEY MESSAGES

- 1) The coastal flood risk will linger through mid-week.

- 2) Rising temperatures into mid week, remaining above normal through the remainder of the week.

DISCUSSION

KEY MESSAGE 1: The coastal flood risk will linger through mid- week.

Coastal flooding concerns continue across the region heading into the new week in the wake of a departing nor'easter. While wind direction may be less favorable than this weekend, still expect astro tides to remain elevated given the recent full moon. This will result minor (to possibly moderate) coastal flooding with each high tide cycle (especially for the Charleston Harbor).

Charleston Harbor: With the ongoing environmental conditions and recently observed departures, tidal levels could reach ~7.3 ft MLLW during this morning's high tide (925 AM). Thus, A Coastal Flood Advisory will be in effect for Charleston and Coastal Colleton Counties from 7 AM until 12 PM.

Fort Pulaski: While tides will remain elevated at Ft Pulaski, they should remain below minor flooding, peaking around 9 to 9.1 ft MLLW through mid-week.

KEY MESSAGE 2: Rising temperatures into mid week, remaining above normal through the remainder of the week.

Upper level ridging will build into the region through mid-week. Today will be slightly warmer than the weekend with highs in the mid-80s. Clear skies and light to calm winds will likely result in radiational cooling tonight with lows in the upper 50s inland and lower 60s across the coastal counties. As high pressure builds over the region this week the forecast will likely remain rain-free and feature a warming trend in temperatures. The next chance of rain will be late week and into the weekend.

AVIATION /12Z MONDAY THROUGH FRIDAY/

VFR conditions are expected to prevail at CHS/JZI/SAV terminals through 12Z Tuesday.

Extended Aviation Outlook: VFR.

MARINE

Through Friday: No marine concerns expected as surface high pressure becomes the dominant feature across the local waters. As a high pressure shifts northeastwards of the area on Tuesday, a weak coastal sea breeze will develop in the afternoon hours, leading to marginally breezy conditions along the coast.
