DISCUSSION AND OUTLOOK
----------------------
At 1100 PM AST (0300 UTC), the center of Hurricane Erin was located
near latitude 37.3 North, longitude 67.0 West. Erin is moving toward
the east-northeast near 22 mph (35 km/h). A faster northeastward to east-northeastward motion is expected during the next couple of
days. On the forecast track, the center of Erin will move over the
western Atlantic between New England and Bermuda through early
Friday, and then pass south of Atlantic Canada Friday and Saturday.

Maximum sustained winds are near 100 mph (155 km/h) with higher
gusts. Gradual weakening is forecast during the next couple of
days, and Erin is expected to become post-tropical on Saturday.

Erin remains a very large system. Hurricane-force winds extend
outward up to 105 miles (165 km) from the center and tropical-storm
force winds extend outward up to 320 miles (520 km). During the
past few hours, wind gusts to tropical-storm force have been
reported on Bermuda and on Nantucket Island, Massachusetts.

The estimated minimum central pressure is 952 mb (28.12 inches).


HAZARDS AFFECTING LAND
----------------------
Key messages for Erin can be found in the Tropical Cyclone
Discussion under AWIPS header MIATCDAT5 and WMO header WTNT45 KNHC.

WIND: Tropical storm conditions are expected on Bermuda through
early Friday. Wind gusts to tropical storm force are likely through
early Friday along the mid-Atlantic and southern New England coast.
Gusts to gale force are possible along portions of the coast of Nova
Scotia on Friday and the Avalon Peninsula of Newfoundland on
Saturday.

SURF: Swells generated by Erin will affect the Bahamas, Bermuda,
the east coast of the United States, and Atlantic Canada during the
next several days. These rough ocean conditions are expected to
cause life-threatening surf and rip currents. Please consult
products from your local weather forecast office for more
information.

STORM SURGE: Water levels remain elevated along the U.S.
Mid-Atlantic and southern New England coasts, but will gradually
recede through Friday. See updates from your local National Weather
Service office for details.
