DISCUSSION AND OUTLOOK
----------------------
At 500 PM AST (2100 UTC), the center of Post-Tropical Cyclone Earl
was located near latitude 43.6 North, longitude 52.6 West. The
post-tropical cyclone is moving toward the north-northeast near 10
mph (17 km/h). A turn toward the northeast at a slow forward speed 
is expected tonight. Earl is expected to be southeast of 
Newfoundland Sunday through Monday.

Maximum sustained winds are near 85 mph (140 km/h) with higher
gusts. Gradual weakening is expected, and Earl's winds are likely 
to fall below hurricane force tonight or early Sunday.

Hurricane-force winds extend outward up to 90 miles (150 km) from
the center and tropical-storm-force winds extend outward up to 485
miles (780 km). A Canadian automated station near Cape Race 
recently reported a wind gust of 68 mph (109 km/h).

The estimated minimum central pressure is 964 mb (28.47 inches).

WIND:  Strong winds are expected across the Avalon Peninsula of
