Synopsis for the the SW N Atlantic including the Bahamas .SYNOPSIS...Post-Tropical Cyclone Tammy is near 32.4N 53.3W at 5 AM EDT, and is moving east at 16 kt. Maximum sustained winds are 35 kt with gusts to 45 kt, and the minimum central pressure is 1002 mb. Tammy will become a remnant low and move to 31.6N 50.4W this afternoon, 30.1N 47.6W Mon morning, 28.5N 46.7W Mon afternoon, 27.2N 46.6W Tue morning, 26.1N 48.0W Tue afternoon, and dissipate Wed morning. High pressure across the middle Atlantic coastal states is combining with a low level trough than extends from a 1007 mb low pressure located just N of Dominican Republic to produce an area of fresh to locally strong winds over the northern semicircle of the low. A short-lived tropical depression or storm could form later today while this system moves west- northwestward. By Monday, however, strong upper-level winds and dry air should end the chances of further development. A strong cold front will enter the NW waters Wed.
