(INVEST 94L) 1. Southwestern Atlantic (AL94): Satellite data and surface observations indicate that a low pressure system appears to be forming near eastern Cuba and the southeastern Bahamas.  This system is producing a large area of disorganized showers and thunderstorms, and gusty winds. Gradual development of this system is expected, and it will likely become a tropical depression during the next day or so while it moves northwestward or northward across the central and northwestern Bahamas.

Regardless of development, heavy rains and gusty winds are ongoing in the Dominican Republic, Haiti, the Turks and Caicos Islands, the southeastern Bahamas and eastern Cuba, and are likely to spread across the remainder of the Bahamas over the weekend. Interests in all of these areas should monitor the progress of the system.  Tropical storm watches or warnings could be required for portions of the Bahamas and advisories on a potential tropical cyclone could be issued as early as later today. While there remains considerable uncertainty in the long-range track and intensity of the system, there is a significant risk of wind, rainfall, and storm surge impacts for a portion of the southeast U.S. coast early next week.  Interests in this area should also monitor the progress of the system.
