At 1100 PM AST (0300 UTC), the center of Hurricane Gaston was
located near latitude 36.0 North, longitude 45.4 West.  Gaston is
moving toward the northeast near 20 mph (31 km/h).  A turn toward
the east-northeast with an increase in forward speed is expected
during the next day or so.  On the forecast track, the center of
Gaston will move near the western and central Azores on Friday.

Maximum sustained winds remain near 105 mph (165 km/h) with higher
gusts.  Weakening is forecast during the next 48 hours, and Gaston
is expected to lose hurricane intensity by early Friday before it
reaches the western Azores.

Hurricane-force winds extend outward up to 45 miles (75 km) from the
