At 500 AM AST (0900 UTC), the center of Tropical Storm Gaston was
located near latitude 38.5 North, longitude 34.5 West. Gaston is
moving toward the east near 15 mph (24 km/h).  An east-northeastward
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).


HAZARDS AFFECTING LAND

later this morning and in the central Azores tonight.

RAINFALL:  Gaston is expected to produce total rain accumulations of
1 to 3 inches, over the western and central Azores, through
Saturday.

SURF:  Swells generated by Gaston are affecting the Azores and will
