from 1000 fm to 250 nm offshore.

Conditions given represent the highest within that period.

more than twice the significant wave height.

.SYNOPSIS FOR MID ATLC WATERS...A long duration gale event, with
winds opposing the Gulf Stream current, is expected to dominate
most of the waters today into early next week. This strong
counterflow to the Gulf Stream will create large, very steep, and
possibly breaking waves resulting in a particularly hazardous sea
state. Low pressure NE of the northern waters will move NE away
from the area today. A strong cold front extends SW from the low
over the far eastern portions of the southern offshore waters
early today, with a weak low located along the front over these
waters. The cold front will progress slowly to the E and SE
today, and shift SE of the area by tonight. Strong high pressure
will build to the N and NW of the front into Sun night, then
remain nearly stationary W of the area Mon and Mon night. The
high will weaken and drift S to the SE states Tue and Tue night,
and then drift E off the coast Wed and Wed night. Hurricane Teddy
is forecast to move to 33.1N 61.6W at 8 AM EDT Mon, to 37.1N
61.2W at 8 PM EDT Mon, to 40.8N 61.8W at 8 AM Tue, then continue
N during Tue night into Wed while becoming a post-tropical
cyclone and moving inland over Nova Scotia and Newfoundland Tue
night into Wed. Long period E and SE swell from Teddy will move
into the waters tonight, and persist into next week. For details
on Teddy please see the latest information from the National
Hurricane Center.
