NOAA: Shower and thunderstorm activity associated with a tropical wave located about 600 miles east of the Lesser Antilles has increased since yesterday. However, environmental conditions are only marginally conducive, and any development of this system should be slow to occur while it moves westward at 15 to 20 mph. This disturbance is expected to bring locally heavy rainfall and gusty winds to portions of the Lesser Antilles beginning later today through Sunday night.
