DISCUSSION AND OUTLOOK

At 300 PM GMT (1500 UTC), the center of Post-Tropical Cyclone
Gabrielle was located near latitude 40.0 North, longitude 22.8 West.
The post-tropical cyclone is moving toward the east-northeast near
31 mph (50 km/h). A turn toward the east with a decrease in forward
speed is expected through Saturday, followed by a turn toward the
southeast and south through early next week. On the forecast track,
the center of post-tropical Gabrielle will continue moving away from
the Azores today, then approach the coast of Portugal by early
Sunday.

Maximum sustained winds are near 65 mph (100 km/h) with higher
gusts. Some strengthening is forecast through tonight, with
weakening expected over the weekend.

Tropical-storm-force winds extend outward up to 175 miles (280 km)
from the center.

The estimated minimum central pressure is 992 mb (29.30 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: Gusty winds across the central and southeastern Azores will
continue to diminish this afternoon.

RAINFALL: Gabrielle is expected to produce less than an inch, or 25
mm, of additional rainfall across the Azores today. Any flooding
caused by Gabrielle across the terrain of the central Azores should
subside today.

SURF: Swells generated by Gabrielle will affect the Azores through
the weekend and will reach the coasts of Portugal, northwestern
Spain, and northern Morocco on Saturday. These swells are expected
to produce life-threatening surf and rip current conditions. Please
consult products issued by your local weather office.
