At 1100 AM AST (1500 UTC), the center of Hurricane Kirk was located
near latitude 23.0 North, longitude 48.9 West. Kirk is moving toward
the northwest near 12 mph (19 km/h), and this general motion is

weekend.

Maximum sustained winds are near 140 mph (220 km/h) with higher
gusts.  Kirk is a category 4 hurricane on the Saffir-Simpson
Hurricane Wind Scale.  Small intensity fluctuations are possible
today and tonight. Weakening is forecast to begin on Saturday and
continue through early next week.

Hurricane-force winds extend outward up to 35 miles (55 km) from the

(315 km).

The estimated minimum central pressure is 939 mb (27.73 inches).


HAZARDS AFFECTING LAND

SURF:  Swells generated by Kirk are spreading westward and are
expected to reach the Leeward Islands later today, Bermuda and the
Greater Antilles on Saturday, the east coast of the United States,
Atlantic Canada, and the Bahamas on Sunday, and the Azores on
Monday. These swells are likely to cause life-threatening surf and
rip current conditions. Please consult products from your local
weather office.
