Maximum sustained winds are near 40 mph (65 km/h) with higher gusts. Additional weakening is expected, and Tammy is forecast to become a post-tropical remnant low as soon as tomorrow.

Shower and thunderstorm activity has increased with a small area of low pressure located about 200 miles northeast of the coast of the Dominican Republic. While upper-level winds are only marginally conducive for further development, this system could become a short-lived tropical depression or storm over the next day or so.

By Monday, upper-level winds are forecast to become too strong for further development as the system turns northward to the east of the northwestern Bahamas.
