WHAT HAS CHANGED

All sections.

KEY MESSAGES

- 1) Mainly dry conditions through the middle of next week.

- 2) Minor coastal flooding is possible along portions of the South Carolina coast with evening high tides through Tuesday.

DISCUSSION

KEY MESSAGE 1: Mainly dry conditions through the middle of next week.

Dry high pressure will build into the area through Friday, then push off the Southeast coast on Saturday. Mid-level height increases and southerly flow over the weekend will result in warming temperatures.

Moisture will gradually increase toward the middle and latter part of next week. Upper disturbances could bring some showers and tstms Wednesday into Thursday.

KEY MESSAGE 2: Minor coastal flooding is possible along portions of the South Carolina coast with evening high tides through Tuesday.

Astronomical tides will be rising due to the upcoming New Moon (on Saturday). In fact, the Charleston astronomical tide alone is expected to peak just above 6.7 ft MLLW with the Saturday and Sunday evening high tides. Therefore, even small positive anomalies could lead to minor coastal flooding for Charleston and Coastal Colleton Counties both of those evenings. This will all be highly dependent on the wind direction the next few days. Overall, each high tide through at least Tuesday will need to be monitored for potential flooding.

AVIATION /18Z THURSDAY THROUGH TUESDAY/

VFR.

Extended Aviation Outlook: VFR.

MARINE

A brief NE wind surge will occur Friday morning following a reinforcing dry cold front moving through from the north. However, wind gusts currently expected to remain below 25 kt.

Otherwise, high pressure will maintain tranquil marine conditions through the middle of next week.

Rip Currents: Slightly increasing tidal ranges with the upcoming new moon plus modest onshore swell will result in Moderate Risk Friday for GA coast and Moderate Risk SC/GA on Saturday.
