1. A tropical depression is expected to form later today over the northern Gulf of Mexico. Conditions appear favorable for this system to strengthen to a hurricane that will bring storm surge, rainfall, and wind hazards to the central Gulf Coast. 2. A dangerous storm surge is possible in portions of southern and southeastern Louisiana where a Storm Surge Watch is in effect. Additional storm surge watches may be needed later today. Residents in these areas should monitor the progress of this system and listen to any advice given by local officials. 3. A Hurricane Watch is in effect for much of the Louisiana coast and additional tropical storm or hurricane watches and warnings could be required. Residents in the watch area should ensure they have their hurricane plan in place. 4. The slow movement of this system will result in a long duration heavy rainfall threat along the central Gulf Coast and inland through the lower Mississippi Valley through the weekend and potentially into early next week. Flash flooding and river flooding will become increasingly likely, some of which may be significant, especially along and east of the track of the system.
