Bahamas. A cold front that currently extends from 30N55W to

behind the front tonight through Tue night, then large N to NE 
swell will move south of 31N and spread across all Atlantic 
waters into Thu night with the next frontal system approaching 
from the north. Gale conditions are possible Tue night through
