HAZARDS AFFECTING LAND ---------------------- Key messages for Gabrielle can be found in the Tropical Cyclone Discussion under AWIPS header MIATCDAT2 and WMO header WTNT42 KNHC. SURF: Swells generated by Gabrielle are beginning to reach Bermuda and will build through the weekend. Swells generated by Gabrielle should reach the east coast of the United States from North Carolina northward, along with Atlantic Canada, later this weekend into early next week. These swells are likely to cause life-threatening surf and rip current conditions. Please consult products from your local weather office.
