DISCUSSION AND OUTLOOK
----------------------
At 500 PM AST (2100 UTC), the center of Tropical Storm Sebastien was
located near latitude 39.2 North, longitude 32.5 West. Sebastien is
moving toward the east-northeast near 39 mph (63 km/h).  An even
faster motion toward the northeast or east-northeast is expected
during the next day or so.  On the forecast track, the center of
Sebastien will pass near the western Azores tonight.

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 day or so. Sebastien is forecast to become post-tropical
by early Monday, and it could degenerate into a trough of low
pressure at any time during the next couple of days. Regardless of
status, Sebastien or its remnants will likely continue to produce
tropical-storm-force winds for at least a couple more days.

Tropical-storm-force winds extend outward up to 140 miles (220 km)
from the center.

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


HAZARDS AFFECTING LAND
----------------------
WIND AND RAIN:  Sebastien or its remnants are expected to bring
gusty winds and rain to the Azores through Monday morning. 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 affect the
Azores during the next couple of days.  These swells are likely to
cause life-threatening surf and rip current conditions.
