DISCUSSION AND OUTLOOK
----------------------
At 1100 AM AST (1500 UTC), the center of Tropical Storm Sebastien
was located near latitude 37.4 North, longitude 37.0 West. Sebastien
is moving quickly toward the northeast near 32 mph (52 km/h). A
faster motion toward the 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 couple of days. 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 115 miles (185 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 beginning later today and
tonight.  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 later today and tonight.  These swells are likely to cause
life-threatening surf and rip current conditions.
