DISCUSSION AND OUTLOOK
At 1100 AM AST (1500 UTC), the center of Post-Tropical Cyclone
Lorenzo was located near latitude 44.4 North, longitude 25.8 West.
The post-tropical cyclone is moving toward the northeast near 43 mph
(69 km/h). A continued fast motion toward the northeast is expected
through Thursday morning. The cyclone is forecast to slow down and
turn eastward and then southeastward Thursday night and Friday. On
the forecast track, the center of post-tropical Lorenzo will move
near western Ireland on Thursday, then pass over Ireland and England
on Thursday night and Friday.
Maximum sustained winds are near 80 mph (130 km/h) with higher
gusts. Only slow weakening is forecast during the next day or so,
and the system is expected to be a strong extratropical cyclone when
it approaches Ireland Thursday afternoon and evening. A faster rate
of weakening is expected when the cyclone moves over Ireland and
Lorenzo is a very large cyclone. Hurricane-force winds extend
outward up to 150 miles (240 km) from the center and tropical-storm-
force winds extend outward up to 390 miles (630 km).
The estimated minimum central pressure is 962 mb (28.41 inches).
