At 1100 PM AST (0300 UTC), the center of Tropical Storm Sebastien

is moving toward the northeast near 31 mph (50 km/h), and an even
faster motion in that general direction is expected during the next
day or two.

Maximum sustained winds are near 65 mph (100 km/h) with higher
gusts.  A slow decrease in the maximum winds is expected
during the next couple of days. Sebastien is forecast to become
post-tropical late on Sunday and dissipate early next week.

Tropical-storm-force winds extend outward up to 90 miles (150 km)
from the center.

The estimated minimum central pressure is 994 mb (29.36 inches).


HAZARDS AFFECTING LAND

WIND AND RAIN: Regardless of its status, Sebastien or its remnants
are expected to bring gusty winds and rain to the Azores beginning
Sunday. Please see products issued by the Portuguese Institute for
the Sea and the Atmosphere (IPMA) for more information.

SURF:  Swells generated by Sebastien are expected to reach the
Azores early next week. These swells are likely to cause
life-threatening surf and rip current conditions.
