A surface trough located about 100 miles east of the southeastern Bahamas is producing a large area of cloudiness and shower activity along and to the east of the trough axis. Upper-level winds are expected to be marginally conducive for slow development of this system while it moves west-northwestward at around 10 mph through Monday, followed by a slow northwestward motion through the end of the week.
