.Synopsis for Jupiter Inlet to Ocean Reef FL out to 60 nm and for
East Cape Sable to Bonita Beach FL out to 60 nm...

As Hurricane Erin passes east of the Florida peninsula early this
week, flow across local waters will remain north-northeasterly
across Atlantic waters and northwesterly across Gulf waters. Surface
winds become westerly towards the end of the week as Erin continues
northward.

Northeasterly swell from this system may increase wave heights
across the northern Gulf stream waters towards the middle of this
week, however current guidance indicates that conditions should
remain below hazardous levels for most of the local waters at this
time. Scattered showers and thunderstorms may affect the local
waters each day this week. Any showers or thunderstorms are capable
of producing brief periods of rough seas and gusty winds.

Gulf Stream Hazards: None.

The approximate location of the west wall of the Gulf Stream as of
Aug 19, 2025.

  1 nautical miles north northeast of Fowey Rocks.
  7 nautical miles east of Port Everglades.
  6 nautical miles south southeast of Lake Worth.
 11 nautical miles east southeast of Jupiter Inlet.
