AMZ400: Synopsis for Altamaha Sound GA to Flagler Beach FL out to 60 nm
822 PM EDT Mon Aug 19 2019

Weak low pressure will meander over western Georgia through Tuesday. The axis of Atlantic ridging will slowly lift northward from a position across central Florida early this week to the northeast Florida waters by midweek. A frontal boundary will then move into the southeastern states from the north late this week and is expected to stall just north of the Georgia waters by next weekend.

Gulf Stream
The approximate location of the west wall of the Gulf Stream as of Aug 17, 2019 at 1200 UTC...
- 62 nautical miles east of Flagler Beach.
- 75 nautical miles east of Saint Augustine Beach.
- 89 nautical miles east of Jacksonville Beach.
- 89 nautical miles east southeast of St Simons Island.
Area Forecast Discussion
National Weather Service Jacksonville FL
903pm EDT Monday August 19 2019

Convection has already faded out for most the of the region, with only some only a few lingering isolated showers remaining. Calm weather is expected tonight through tomorrow morning, with mild winds and high level clouds which should help to prevent widespread fog from developing in the early morning hours. With the ridging pressing in from the east moving to cover more of northeast Florida and southeast Georgia, weather developments tomorrow are expected to be scattered showers and potential thunderstorms in the afternoon and evening.

Marine Discussion
The lack of strong pressure features results in light winds and shallow seas throughout this week. Another frontal feature approaches the northern waters late this week into the weekend, but uncertainty remains on how far south it pushes.

Rip Currents
Low risk of rip currents, with a minor increase during the afternoon as the sea-breeze moves inland.
