DISCUSSION AND OUTLOOK
----------------------
At 1100 AM AST (1500 UTC), the center of Hurricane Erin was located
near latitude 38.8 North, longitude 63.1 West. Erin is moving toward
the east-northeast near 28 mph (44 km/h).  This general motion with
an increase in forward speed is expected later today, followed by a
turn back to the northeast on Sunday.  On the forecast track, the
center of Erin will pass south of Atlantic Canada today and tonight,
and then race across the north Atlantic waters.

Maximum sustained winds are near 90 mph (150 km/h) with higher
gusts.  Erin is likely to become post-tropical by tonight but remain
a powerful hurricane-force low pressure system through the weekend.

Erin is growing in size.  Hurricane-force winds extend outward up
to 140 miles (220 km) from the center and tropical-storm-force
winds extend outward up to 435 miles (705 km).

The estimated minimum central pressure is 956 mb (28.23 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:  Gale-force wind gusts 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.
