439 FZNT26 KNHC 200316 OFFN05 NAVTEX Marine Forecast NWS National Hurricane Center Miami, FL 1116 PM EDT Tue Aug 19 2025 ...Please refer to Coastal Waters Forecasts (CWF) available through NOAA Weather Radio and other means for detailed Coastal Waters Forecasts... .SYNOPSIS...Now that Hurricane Erin has pulled father away from the regional waters, with latest location as of 0300 UTC near 27.7N 73.0W, or about 510 nm west-southwest of Bermuda, central Atlantic pressure will build west-southwestward toward the Bahamas. This will allow for the normal trade wind flow to return to the regional waters through the period. Meanwhile, a tropical wave located over the central tropical Atlantic continues to produce a broad area of disorganized showers and thunderstorms. Environmental conditions appear conducive for gradual development of this system, and a tropical depression could form late this week or over the weekend while it moves near or to the north of the northern Leeward Islands.
