DISCUSSION AND OUTLOOK
At 500 PM AST (2100 UTC), the center of Hurricane Leslie was located
near latitude 33.9 North, longitude 24.1 West. Leslie is moving
toward the east-northeast near 35 mph (56 km/h). A fast motion
toward the east-northeastward is expected to continue through
Saturday, followed by a slower east-northeastward motion Saturday
night and Sunday. On the forecast track, the center of Leslie will
pass north of Madeira Island tonight and early Saturday, approach
the southwestern portion of the Iberian Peninsula on Saturday, and
move inland over portions of the Iberian Peninsula late Saturday
Maximum sustained winds are near 85 mph (140 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, and the post-
tropical cyclone is expected to dissipate by Monday.
Hurricane-force winds extend outward up to 70 miles (110 km),
mainly to the south of the center. Tropical-storm-force winds extend
outward up to 230 miles (370 km).
The estimated minimum central pressure is 971 mb (28.68 inches).
HAZARDS AFFECTING LAND
WIND: Tropical storm conditions are expected on Madeira Island
beginning early Saturday.
Post-tropical Leslie will bring winds to near hurricane-force to
portions of Portugal late Saturday, and tropical-storm-force winds
to portions of western Spain late Saturday and Saturday night.
Please see products from your local meteorological service for more
information on this hazard.
RAINFALL: Leslie is expected to produce total rain amounts of 1 to
3 inches (25 to 75 mm) with localized amounts up to 4 inches (100
mm) across Portugal and portions of Spain through Sunday night.
This rainfall may lead to some instances of flash flooding.
SURF: Swells generated by Leslie will likely affect portions of
the Azores, Madeira Island and the Canary Islands through Saturday
and will reach the Atlantic coasts of Spain, Portugal, and Morocco
over the weekend. These swells are likely to cause life-threatening
surf and rip current conditions. Please consult products from your
local weather office.
