General Situation: Deep-layered low pressure system north of the Greater Antilles Islands with ta rough across the SE Bahamas is interacting with the remnant moisture of Isaac near Jamaica to produce some unsettled weather across the area. Moisture and trough will gradually shift westward and northeastward this week as it moves pockets of unsettled weather through the Central and SE Bahamas through Wednesday. A weak upper level trough will move across the NW Bahamas from the northeast, then across the Central Bahamas before shifting into the eastern Gulf of Mexico as an upper level low. As the weekend approaches a broad surface high pressure system from the eastern United States will build across the area with the usual summer-type conditions expected.

Beachgoers and Mariners should exercise extreme caution due to the risk of large swells and dangerous rip currents along the eastern shorelines for the entire forecast period. Boaters and Beachgoers should be alert for possible waterspout activity and take all necessary precautions to protect life and property. Residents should be alert for the risk of localized flooding during heavy downpours and prolonged rainfall events. Residents and Beachgoers should keep hydrated and avoid outdoors or protect themselves during the hottest parts of the day as these periods are when high heat indices occur during the summer time.
