|HEAVY RAIN POTENTIAL IN GREEN POLYGON|
Showers and thunderstorms associated with a broad area of low pressure located over the southwestern Gulf of Mexico continue to show signs of organization. Environmental conditions are expected to be conducive for additional development, and a tropical or subtropical storm is likely to form later today or tonight while the system moves generally northeastward over the western Gulf of Mexico. The low is forecast to approach the northern or northeastern Gulf Coast on Friday or Saturday and regardless of development, the system is likely to produce gusty winds and rough surf over those areas. Locally heavy rainfall is also possible across portions of the southeast U.S. late this week and this weekend. Interests along the northern and northeastern Gulf coast should monitor the progress of this system. For more information about marine hazards while the low moves across the Gulf of Mexico, see products issued by the Tropical Analysis and Forecast Branch of the National Hurricane Center. An Air Force Reserve reconnaissance aircraft is scheduled to investigate the system this afternoon, if necessary.
