At 1100 PM AST (0300 UTC), the center of Hurricane Leslie was

southwestern portion of the Iberian Peninsula on Saturday, and move
inland over portions of Portugal and Spain late Saturday and Sunday.
Maximum sustained winds are near 80 mph (130 km/h) with higher
gusts. Leslie is expected to transition into a hurricane-force
post-tropical cyclone on Saturday. Weakening is forecast after
Leslie moves inland over the Iberian Peninsula Saturday night, and
the post-tropical cyclone is expected to dissipate by Monday.
Hurricane-force winds extend outward up to 60 miles (95 km) from the
center, and tropical-storm-force winds extend outward up to 205
miles (335 km).
The estimated minimum central pressure is 976 mb (28.82 inches).
