.SYNOPSIS FOR MID ATLC WATERS...A stationary front will persist
across the central waters tonight, with high pressure over the N
waters to the N of the front. The front and high pressure will

Wed, then continue N and NE through the outer S and central
waters Wed night and Thu. It will then turn more NE and move
through the Outer Mid-Atlantic Waters Thu night through Fri
night. Long period SE to S swell from Erin will continue to
spread N into the central and N waters tonight. 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 while a stationary front forms over the far
S waters. The high will shift E of the region Sat night through
Sun night, while a cold front will approach the area from the W
Sun night. For more information on Hurricane Erin, please closely
monitor the latest forecasts from the National Hurricane Center.
