DISCUSSION AND OUTLOOK
At 800 AM AST (1200 UTC), the center of Hurricane Leslie was located
near latitude 37.3 North, longitude 14.5 West. Leslie is moving
toward the east-northeast near 38 mph (61 km/h). A motion toward
the east-northeast with a gradual decrease in forward speed is
expected through Sunday. On the forecast track, the center of
Leslie will approach the southwestern portion of the Iberian
Peninsula today, and move inland over portions of Portugal and Spain
tonight and Sunday.
Maximum sustained winds are near 75 mph (120 km/h) with higher
gusts. Leslie is expected to transition into a hurricane-force
post-tropical cyclone later today. Weakening is forecast after
Leslie moves inland over the Iberian Peninsula later today or
early Sunday, and the post-tropical cyclone is expected to dissipate
by Sunday night or 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 980 mb (28.94 inches).
HAZARDS AFFECTING LAND
WIND: Post-tropical Leslie will bring winds to near hurricane-force
to portions of Portugal later today or tonight, and gale-force winds
to portions of western Spain later today through early Sunday.
Please see products from your local meteorological service for more
information on this hazard.
RAINFALL: Leslie is expected to produce total rainfall accumulations
of 1 to 3 inches (25 to 75 mm) with localized amounts up to 5 inches
(125 mm) across portions of Portugal and Spain this weekend. This
rainfall may lead to some instances of flash flooding.
SURF: Swells generated by Leslie will continue to affect the
Azores, Madeira Island, and the Canary Islands through the weekend,
and will begin to affect the Atlantic coasts of Spain, Portugal, and
Morocco today and continuing into Sunday. These swells are likely
to cause life-threatening surf and rip current conditions. Please
consult products from your local weather office.
