Discussion

At 500 p.m. AST (2100 UTC), the center of Post-Tropical Cyclone Leslie was located near latitude 40.5 north, longitude 9.5 west. The post-tropical cyclone is moving toward the northeast near 35 mph (56 km/h) and this motion is expected to continue during the next 24 hours with a decrease in forward speed. On this track, the center of Leslie will be near the west-central coast of portugal in a few hours, and move inland over portions of central and northern portugal tonight, and across northwestern and northern spain Sunday morning.

Maximum sustained winds are near 70 mph (110 km/h) with higher gusts. Weakening is forecast after Leslie moves inland over the iberian peninsula, and the cyclone is forecast to dissipate by Sunday afternoon or evening.

Tropical-storm-force winds extend outward up to 160 miles (260 km) from the center. Lisbon, portugal recently reported a wind gust to 40 mph (65 km/h).

The estimated minimum central pressure is 984 mb (29.06 inches).
