DISCUSSION AND OUTLOOK
———————-
At 1100 PM AST (0300 UTC), the center of Hurricane Leslie was
located near latitude 30.9 North, longitude 33.9 West. Leslie is
moving toward the east-northeast near 26 mph (43 km/h). A continued
east-northeast motion with an increase in forward speed is expected
through Friday. Leslie is forecast to slow down and turn toward the
east or east-southeast by Saturday. On the forecast track, Leslie
will pass near Madeira Island by late Saturday.

Maximum sustained winds have increased to near 90 mph (150 km/h)
with higher gusts. Some gradual weakening is forecast during the
next 72 hours, and Leslie could transition into a post-tropical low
by Sunday.

Hurricane-force winds extend outward up to 75 miles (120 km) from
the center and tropical-storm-force winds extend outward up to 205
miles (335 km).

The estimated minimum central pressure is 969 mb (28.62 inches).

HAZARDS AFFECTING LAND
———————-
WIND: Tropical storm conditions are expected on Madeira Island
beginning early Saturday.

RAINFALL: Leslie is expected to produce storm total accumulations
of 3 to 6 inches across Madeira Island through Sunday. This could
lead to flash flooding and landslides over mountainous terrain.

SURF: Swells generated by Leslie will likely affect portions of
the Azores, Madeira Island and the Canary Islands through Saturday
and could 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.
