Additional watches and/or warnings could be required on Tuesday. For storm information specific to your area, please monitor products issued by your national meteorological service. DISCUSSION AND OUTLOOK ---------------------- At 1100 PM AST (0300 UTC), the center of Hurricane Teddy was located near latitude 35.6 North, longitude 61.5 West. Teddy is moving toward the north near 25 mph (41 km/h), and this motion is expected overnight followed by a turn toward the north-northwest on Tuesday. Teddy should turn toward the north-northeast and move over eastern Nova Scotia on Wednesday then over the Gulf of St. Lawrence late Wednesday into Thursday. Maximum sustained winds have increased to near 100 mph (155 km/h) with higher gusts. Teddy could gain a little more strength overnight, but should weaken steadily by Wednesday and become a strong post-tropical cyclone near Nova Scotia. Hurricane-force winds extend outward up to 105 miles (165 km) from the center and tropical-storm-force winds extend outward up to 275 miles (445 km). An Air Force Reserve Hurricane Hunter aircraft recently reported a minimum central pressure of 956 mb (28.23 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 and on the web at https://www.hurricanes.gov/text/MIATCDAT5.shtml. WIND: Tropical storm conditions are expected to begin in the warning area by Tuesday afternoon. Tropical storm conditions could begin in the watch areas late Tuesday or early Wednesday. SURF: Large swells generated by Teddy are affecting Bermuda, the Lesser Antilles, the Greater Antilles, the Bahamas, the east coast of the United States, and Atlantic Canada. These swells are likely to cause life-threatening surf and rip current conditions. Please consult products from your local weather office. RAINFALL: From Tuesday through Thursday, Teddy is expected to produce rainfall accumulations of 2 to 4 inches (50 to 100 mm) with isolated totals of 6 inches (150 mm) across sections of Atlantic Canada. STORM SURGE: A dangerous storm surge is expected to produce significant coastal flooding near and to the east of where the center makes landfall in Nova Scotia. Near the coast, the surge will be accompanied by very large and destructive waves. NEXT ADVISORY ------------- Next intermediate advisory at 200 AM AST. Next complete advisory at 500 AM AST. $$ Forecaster Roberts
