.SYNOPSIS FOR MID ATLC WATERS...Low pressure just E of the S
waters will lift slowly NE along a stationary front tonight while
a cold front moves S into the N waters. The cold front will
become stationary across the central waters tonight through Tue
night. High pressure will build S into the N waters behind the
front, then move NE away from the area Wed. The eye of Hurricane
Erin is expected to move N into the outer S waters late Wed, then
continue N and NE through the outer S and central waters Wed
night and Thu before turning more NE and moving through the Outer
Mid-Atlantic Waters Thu night through Fri night. Tropical storm
conditions are expected over most of the area SE of a line from
the Virginia Capes to Georges Bank. Long period SE to S swell
from Erin, already affecting the waters, will spread N into the
central and N waters late tonight through Tue night. Significant
swell will continue through Fri night while gradually backing to
the E Wed through Thu night. Another high will build over
the waters Fri through Sat night. For more information on Hurricane
Erin, please closely monitor the latest forecasts from the
