Marine Weather and Tide Forecast for Seabrook Island, SC

KEY MESSAGES
- 1) Rain-free conditions dominate this week as high pressure prevails.

DISCUSSION
KEY MESSAGE 1: Rain-free conditions dominate this week as high pressure prevails.

Quiet conditions will remain across the region under the influence of surface high pressure and ridging aloft. High temperatures today will be right around normal in the upper 70s to low 80s. As the surface high pressure shifts offshore later this week highs will warm to above normal, with mid to upper 80s in the forecast.

Unfortunately, no rainfall is in the forecast until late this weekend, and even that is uncertain. Dry conditions will lead to an enhanced fire danger through the week, with RH values dropping as low as 20% west of I-95. While RH values will be critical, the winds are expected to top out around 10 to 15 mph. Therefore, no fire weather headlines will be issued at this time. That being said, we encourage folks to exercise extreme caution if burning and heed any local burn bans as conditions remain very dry.

AVIATION /12Z TUESDAY THROUGH SATURDAY/
12Z TAFs: VFR. A weak backdoor cold front will slip across KCHS and KJZI around the onset of TAFs. Winds should remain light and variable ahead of the cold front, then veering from the northeast behind of the front. Northeast winds may not develop over KSAV until 16Z. Recent runs of the HRRR indicates that a weak sea breeze is timed to advance slowly inland late this afternoon and evening, turning steady winds from the east- southeast.

Extended Aviation Outlook: Dry high pressure keeps VFR conditions in place through the remainder of the week. A sea breeze is possible each afternoon and evening.

MARINE
High pressure centered over the western Atlantic will continue to ridge across the marine zones through the rest of the week. This pressure pattern should generally support winds between 10-15 kts and wave heights between 2-3 ft through Sat.
