.SYNOPSIS FOR NEW ENGLAND WATERS...Strong high pressure will
build E over the Mid-Atlantic and New England states today as low
pressure continues to organize along a strong cold front to the 
S of the waters. The high will build E across most of the region
tonight, then shift E Mon into Tue as the organizing low to the S
of the waters moves slowly N toward the area. The low will 
remain S of the area late Tue through Thu before finally moving
E and passing SE of the waters Thu night. Mariners should closely
monitor the latest OPC and coastal marine forecasts over the 
next few days, and vessels should execute avoidance plans 
especially for those transiting the waters from the southern New 
England waters southward over the next several days.
