DISCUSSION AND OUTLOOK
———————-
At 200 AM AST (0600 UTC), the center of Hurricane Erin was located
near latitude 37.9 North, longitude 66.6 West. Erin is moving
toward the 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 this
morning, and then pass south of Atlantic Canada today and Saturday.
Maximum sustained winds are near 90 mph (150 km/h) with higher
gusts. Gradual weakening is forecast during the next couple of
days, but Erin is still expected to be producing hurricane-force
winds when it becomes post-tropical on Saturday.
Erin remains a very large hurricane. Hurricane-force winds extend
outward up to 125 miles (205 km) from the center and
tropical-storm-force winds extend outward up to 370 miles (595 km).
A wind gust to 51 mph (82 km/h) was recently reported at the L. F.
Wade International Airport on Bermuda, and a gust to 47 mph (76
km/h) was measured at the airport on Nantucket, Massachusetts.
The estimated minimum central pressure is 954 mb (28.17 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 for a few
more hours. Wind gusts to tropical storm force are likely through
this morning along the southern New England coast. Gusts to gale
force are possible along portions of the coast of Nova Scotia today
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 today. See updates from your local National Weather
Service office for details.
