.SYNOPSIS FOR NEW ENGLAND WATERS...Low pressure well offshore of 
the North and South Carolina coasts will rapidly intensify into 
a hurricane-force system as it moves northeast to near 40N65W by 
late this evening. Mariners should exercise avoidance now! The 
low will move slowly east-southeast late tonight and Tuesday, 
moving well out into the north Atlantic by Tuesday night. Behind 
the low, high pressure will build over the area, with a cold 
front approaching the waters Tuesday evening. The front slowly 
moves south overnight Tuesday and Wednesday, becoming nearly 
stationary off of the mid-Atlantic coast Wednesday and Wednesday 
night, and then moves north as a warm front Thursday and 
Thursday night ahead of low pressure over the Great Lakes. A cold
front approaches from the west late Thursday and moves through 
much of the area by Friday, becoming nearly stationary over the 
southern waters Friday and Friday night.
