000 FZNT27 KNHC 112039 OFFN06 NAVTEX Marine Forecast NWS National Hurricane Center Miami, FL 439 PM EDT Sat Sep 11 2021 ...Please refer to Coastal Waters Forecasts (CWF) available through NOAA Weather Radio and other means for detailed Coastal Waters Forecasts... .SYNOPSIS...A large area of convection extends across Central America and southern Mexico, related to the interaction of a tropical wave and an upper level trough. Upper-level winds are expected to become favorable for the system during the next day or so. A tropical depression is likely to form on Sunday or Monday while the disturbance moves NW near the coast of northeastern Mexico. Further development will be possible through the middle of next week if it remains over water, and interests along the western and northwestern Gulf coast should monitor the progress of this system. Regardless of development, this disturbance is expected to produce heavy rain across portions of Central America and the Yucatan Peninsula today which may lead to flash flooding and mudslides. By Sun, heavy rain will likely reach portions of the western Gulf coast, including coastal Texas and Louisiana through the middle of next week. Localized significant rainfall amounts will be possible, potentially resulting in areas of flash and urban flooding. Northwest Gulf of Mexico .TONIGHT...E to SE winds 10 to 15 kt. Seas 3 to 5 ft.
