At 1100 AM AST (1500 UTC), the center of Hurricane Tammy was located
near latitude 26.6 North, longitude 59.3 West. Tammy is moving
toward the northeast near 13 mph (20 km/h). A northward turn is
expected later today, followed by a slower northwestward to

Maximum sustained winds have increased to near 105 mph (165 km/h)

HAZARDS AFFECTING LAND

SURF:  Swells generated by Tammy will continue to affect portions of
Bermuda, the northern Leeward Islands, the British and U.S. Virgin
Islands, and Puerto Rico during the next couple of days. These
swells are likely to cause life-threatening surf and rip current
conditions. Please consult products from your local weather office.
