HAZARDS AFFECTING LAND ---------------------- Key messages for Lee can be found in the Tropical Cyclone Discussion under AWIPS header MIATCDAT3 and WMO header WTNT43 KNHC and on the web at hurricanes.gov/text/MIATCDAT3.shtml SURF: Swells generated by Lee are affecting portions of the Lesser Antilles, and are spreading westward to the British and U.S. Virgin Islands, Puerto Rico, Hispaniola, the Turks and Caicos Islands, the Bahamas, and Bermuda over the remainder of this weekend. These swells are likely to cause life-threatening surf and rip current conditions. Dangerous surf and rip currents are expected to begin along most of the U.S. East Coast tomorrow and worsen through next week. Please consult products from your local weather office.
