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.
Ridging aloft will build into the region on Tuesday, lingering through the weekend. At the surface high pressure will center itself over SC early this week. As the week progresses the center of high pressure will shift offshore. This synoptic set-up will yield near normal temperatures to start the week, returning to above normal by the weekend. 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 to >25% across inland locations every afternoon. Winds do not seem to be an issue, peaking only around 10 to 15 mph. While criteria is not met to issue any fire weather products at this time, users should exercise extreme caution if burning and heed any local burn bans as coniditons remain very dry.
AVIATION /06Z MONDAY THROUGH FRIDAY/
6Z TAFs: VFR. Winds should remain steady from the northeast around 5 kts through late this afternoon. A weak sea breeze is forecast to advance slowly inland late this afternoon and evening, turning light winds from the south.
Extended Aviation Outlook: Dry high pressure keeps VFR conditions in place through much of the coming week. A sea breeze is possible each afternoon and evening.
MARINE
High pressure will build across the marine zones today. Gusty winds this morning will diminish this afternoon as a sea breeze develops.
Seas of 6 ft may linger across the outer waters until this afternoon. Small Craft Advisory for the outer GA waters will remain in effect until 5 PM this afternoon. The pressure pattern should support winds around 25 kts and wave heights between 2-3 ft through the remainder of the week.
Rip Currents: Building high pressure will support gusty northeast winds this morning along the coast. The gusty winds should generate a strong longshore current through mid-day. Given the longshore current combined with breakers around 3 ft and lingering elevated tide cycles, a moderate risk will remain for all beaches today.
Decreasing winds along with decreasing tidal range cycles will allow the rip current risk to remain low for Tuesday.
CHS WATCHES/WARNINGS/ADVISORIES
GA...None.
SC...None.
MARINE...Small Craft Advisory until 5 PM EDT this afternoon for AMZ384.
