motion is expected by tonight.  On the forecast track, the center
of Gaston will move near the western Azores today, and pass north of
the central Azores tonight.

Maximum sustained winds have decreased to near 65 mph (100 km/h)
with higher gusts.  Additional weakening is forecast during the
next 36 hours, and Gaston is expected to become a remnant low on
Saturday.

Tropical-storm-force winds extend outward up to 150 miles (240 km)
from the center.

The estimated minimum central pressure is 992 mb (29.30 inches).
