DISCUSSION AND 48-HOUR OUTLOOK
------------------------------
At 800 AM AST (1200 UTC), the center of Hurricane Alex was located
near latitude 38.0 North, longitude 26.9 West. Alex is moving
toward the north near 24 mph (39 km/h). A northward motion at a
faster forward speed is expected later this morning and this
afternoon, followed by a turn toward the north-northwest tonight and
Saturday. On the forecast track, the center of Alex will move near
or over portions of the central Azores during the next few hours.
Maximum sustained winds are near 75 mph (120 km/h) with higher
gusts. Little change in strength is expected over the next day or
so. However, Alex will likely lose its tropical characteristics by
this afternoon or tonight while it moves over colder waters.
Hurricane-force winds extend outward up to 25 miles (35 km) from the
center and tropical-storm-force winds extend outward up to 205 miles
(335 km). Ponta Delgada on Sao Miguel Island recently reported a
sustained wind of 42 mph (69 km/h) and a wind gust of 54 mph (87
km/h). Santa Maria Island recently reported a sustained wind of 39
mph (63 km/h) and a wind gust of 53 mph (85 km/h).
The estimated minimum central pressure is 986 mb (29.12 inches).
HAZARDS AFFECTING LAND
----------------------
WIND: Tropical-storm-force winds will continue across the eastern
and central Azores this morning, with hurricane conditions expected
in the central Azores during the next few hours.
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 today, with possible isolated
maximum amounts of 7 inches. These rains could produce life-
threatening flash floods and mud slides. Rainfall should diminish
across the Azores by late afternoon.
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.
