WHAT HAS CHANGED

The Aviation Section was updated for the 00z TAFs.

KEY MESSAGES

- 1) High pressure will maintain mostly dry conditions this week, with an elevated fire danger.

DISCUSSION

KEY MESSAGE 1: High pressure will maintain mostly dry conditions this week, with an elevated fire danger.

Strong high pressure will continue to build from the northwest through the week with mainly dry conditions. The exception will be a few showers along the GA coast through tonight, and then possible coastal showers Wed-Fri along the SC/GA coast as a weak coastal trough develops.

An elevated fire danger is expected this week due to dipping afternoon RH values and gusty northeast winds. Conditions are not quite to Red Flag criteria but we could need Fire Danger Statements some days.

AVIATION /00Z TUESDAY THROUGH SATURDAY/

07/00z TAF Discussion: KCHS/KJZI/KSAV: VFR through 08/00z. Gusty northeast winds will develop after sunrise with gusts in excess of 20 kt likely at all terminals.

Extended Aviation Outlook: VFR, with breezy NE winds Wednesday and Thursday.

MARINE

Persistent moderate NE winds will continue through the week, with seas steadily building. Solid Gales begin Tuesday afternoon or evening and continue through early Thursday morning during the period of tightest gradient. We upgraded the existing Gale Watches to Gale Warnings with this package and issued a Small Craft Advisory for Charleston Harbor starting late Tuesday evening.

Rip Currents: Increasing NE winds and building swells will result in a Moderate risk for rip currents along the SC coast on Tuesday with a High risk along the GA coast. Wednesday and likely into Thursday we anticipate a High risk for all beaches.

High Surf: High surf and beach erosion could impact the beaches Wednesday through Friday as seas build 8+ feet over the coastal waters. High Surf Advisories may be needed.
