Teddy is moving toward the northwest near 13 mph (20 km/h), and this general motion is expected to continue for the next few days.

Teddy is a category 4 hurricane on the Saffir-Simpson Hurricane Wind Scale. Additional strengthening is expected tonight, and some fluctuations in intensity are possible Friday and Saturday. A weakening trend is expected to begin late this weekend. Teddy is a large hurricane. Hurricane-force winds extend outward up to 60 miles (95 km) from the center and tropical-storm-force winds extend outward up to 230 miles (370 km). The estimated minimum central pressure is 945 mb (27.91 inches). HAZARDS AFFECTING LAND ---------------------- Key messages for Teddy can be found in the Tropical Cyclone Discussion under AWIPS header MIATCDAT5 and WMO header WTNT45 KNHC. SURF: Large swells generated by Teddy are reaching the Lesser Antilles and the northeastern coast of South America and should spread westward to the Greater Antilles, the Bahamas, Bermuda, and the east coast of the United States by the weekend. These swells are likely to cause life-threatening surf and rip current conditions. Please consult products from your local weather office.
