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