DISCUSSION AND OUTLOOK
----------------------
At 1200 PM GMT (1200 UTC), the center of Hurricane Gabrielle was
located near latitude 36.4 North, longitude 36.5 West. Gabrielle is
moving quickly toward the east near 32 mph (52 km/h). A fast
eastward to east-northeastward motion is expected during the next
day or two, followed by a slower eastward to east-southeastward
motion this weekend. On the forecast track, the center of Gabrielle
will approach the Azores today and move across the island chain
tonight into early Friday.

Maximum sustained winds are near 85 mph (140 km/h) with higher
gusts. Gabrielle is forecast to be at hurricane strength when it
passes through the Azores. After that, it is expected to weaken as
an extratropical low through the weekend.

Hurricane-force winds extend outward up to 60 miles (95 km) from
the center and tropical-storm-force winds extend outward up to 195
miles (315 km).

The estimated minimum central pressure is 980 mb (28.94 inches).


HAZARDS AFFECTING LAND
----------------------
Key messages for Gabrielle can be found in the Tropical Cyclone
Discussion under AWIPS header MIATCDAT2 and WMO header WTNT42 KNHC.

WIND: Hurricane conditions are expected in the Azores tonight into
early Friday, with tropical storm conditions likely by this
evening. Significant hurricane-force wind gusts are likely across
portions of the Azores even after the center passes.

STORM SURGE: A dangerous storm surge is expected to produce
significant coastal flooding in areas of onshore winds in the
Azores. The surge will be accompanied by large and destructive
waves.

RAINFALL: From tonight through Friday morning, Gabrielle could
produce up to 3 to 5 inches, 75 to 125 mm, of storm total rainfall
across the central Azores. This rainfall could produce flash
flooding within the mountains. Elsewhere, Gabrielle is expected
to yield 1 to 3 inches, or 25 to 75 mm, of rain across the western
and eastern Azores.

SURF: Swells generated by Gabrielle will continue to affect Bermuda,
the northeastern coast of the U.S., and Atlantic Canada today.
Swells from Gabrielle will begin reaching the Azores later today.
These swells are expected to produce life-threatening surf and rip
current conditions. Please consult products issued by your local
weather office.
