DISCUSSION AND OUTLOOK
At 800 AM AST (1200 UTC), the center of Hurricane Leslie was located
near latitude 32.3 North, longitude 29.8 West. Leslie is moving
toward the east-northeast near 29 mph (46 km/h). A continued east-
northeastward motion with an increase in forward speed is expected
through Friday. Leslie is then 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 are near 90 mph (150 km/h) with higher
gusts. Weakening is forecast during the next 72 hours, and Leslie
could transition into a post-tropical low by Sunday or Sunday night.
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 total rain accumulations
of 1 to 4 inches across Madeira Island through Sunday. This could
lead to flash flooding and mudslides in 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.
