DISCUSSION AND 48-HOUR OUTLOOK
——————————
At 500 PM AST (2100 UTC), the center of Hurricane Alex was located
near latitude 33.6 North, longitude 27.8 West. Alex is moving toward
the north-northeast near 22 mph (35 km/h), and a turn toward the north
with an increase in forward speed is expected by Friday
followed by a turn toward the north-northwest on Saturday. On the
forecast track, the center of Alex will move near or over portions of
the Azores Friday morning.

Maximum sustained winds are near 85 mph (140 km/h) with higher gusts.
Little change in strength is expected over the next day or so, and
Alex is likely to lose its tropical characteristics on Friday.

Hurricane force winds extend outward up to 25 miles (35 km) from the
center, and tropical storm force winds extend outward up to 175 miles
(280 km).

The estimated minimum central pressure is 981 mb (28.97 inches).

HAZARDS AFFECTING LAND
———————-
WIND: Tropical-storm-force winds are expected to begin over portions
of the Azores tonight. Hurricane conditions are expected to spread
over the central Azores by early Friday.

Wind speeds atop and on the windward sides of hills and mountains are
often up to 30 percent stronger than the near-surface winds indicated
in this advisory, and in some elevated locations could be even
greater.

RAINFALL: Alex is expected to produce total rain accumulations of 3 to
5 inches over the Azores through Friday, with possible isolated
maximum amounts of 7 inches. These rains could produce
life-threatening flash floods and mud slides.

STORM SURGE: A dangerous storm surge is expected to produce
significant coastal flooding near and to the east of the center of
Alex. Near the coast, the surge will be accompanied by large and
destructive waves.
