| Area Forecast Discussion National Weather Service New Orleans LA Issued by National Weather Service Jacksonville FL 610am CDT Wednesday September 11 2024 Long Term (Thursday Afternoon through Tuesday) Issued at 346am CDT Wednesday September 11 2024 Once Francine exits our area Thursday, breezy/clearing conditions will build in promoted by upstream convergence on the back side of the system. We'll see comfortable mornings and warm afternoon highs with the return of (much needed) sunshine going into the weekend. Not seeing indications of overly hot temperatures (highs in the mid to upper 80's) - something to keep in mind for those with power outages for extended periods or doing cleanup, with no additional impactful weather well into the middle parts of next week. KLG Marine Issued at 346am CDT Wednesday September 11 2024 Major impacts, including dangerous waves/seas and life- threatening high winds and are expected for all marine areas in association with approaching Hurricane Francine. Conditions are expected to become worse beginning this morning, with observations already ranging 30 to 40kts + and will continue to climb. High wave/seas are expected to build, becoming dangerous and life- threatening into the afternoon, evening and overnight hours. Conditions are expected to improve going into late week, as Francine continues northeast inland and and away from the coast, with building offshore/ weak flow going into the weekend.
