Gabrielle is moving toward the northwest near 13 mph (20 km/h), and this general motion is expected to continue through tonight. A turn toward the north-northwest is forecast on Sunday, followed by a turn toward the north and northeast Monday and Monday night. On the forecast track, the center of Gabrielle is expected to pass east of Bermuda Sunday night and Monday. Maximum sustained winds are now near 60 mph (95 km/h) with higher gusts. Continued gradual strengthening is forecast, and Gabrielle is expected to become a hurricane by Sunday. Air Force Reserve and NOAA Hurricane Hunter aircraft are scheduled to investigate Gabrielle later today. Tropical-storm-force winds extend outward up to 140 miles (220 km) from the center. The estimated minimum central pressure is 1001 mb (29.56 inches). 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.
