Post-Tropical Cyclone Teddy Forecast Discussion Number 47
2020-09-24 04:43:56| National Hurricane Center (Atlantic)
Issued at 1100 PM AST Wed Sep 23 2020 000 WTNT45 KNHC 240243 TCDAT5 Post-Tropical Cyclone Teddy Discussion Number 47 NWS National Hurricane Center Miami FL AL202020 1100 PM AST Wed Sep 23 2020 Teddy is accelerating over the northeastern Gulf of St. Lawrence and will move over the Strait of Belle Isle later, while continuing to fill/decay as an extratropical cyclone. The initial intensity is set at 45 kt, and this is based on the various surface wind and pressure observations along the west coast of Newfoundland from Channel-Port aux Basques northward to Port Saunders and the Straits. Teddy is forecast to maintain its current intensity and motion, with some further increase in forward speed, and merge with a larger, stronger high-latitude extratropical low near the Labrador Sea on Thursday. Even after Teddy passes Nova Scotia and Newfoundland, large swells creating dangerous rip currents will linger over much of the southwestern Atlantic basin for the next few days. This will be the last NHC advisory on Teddy. For additional information, including warnings, consult products issued by Environment Canada at: weather.gc.ca/hurricane/index_e.html For marine interests, additional information can be found in High Seas Forecasts issued by the National Weather Service under AWIPS header NFDHSFAT1 and WMO header FZNT01 KWBC.

SUMMARY OF 1100 PM AST...0300 UTC...INFORMATION ----------------------------------------------- LOCATION...51.0N 57.3W ABOUT 530 MI...850 KM NNE OF HALIFAX NOVA SCOTIA ABOUT 355 MI...570 KM NNW OF CAPE RACE NEWFOUNDLAND MAXIMUM SUSTAINED WINDS...50 MPH...85 KM/H PRESENT MOVEMENT...NNE OR 30 DEGREES AT 32 MPH...52 KM/H MINIMUM CENTRAL PRESSURE...975 MB...28.80 INCHES WATCHES AND WARNINGS -------------------- CHANGES WITH THIS ADVISORY: None. SUMMARY OF WATCHES AND WARNINGS IN EFFECT: There are no coastal watches or warnings in effect. DISCUSSION AND OUTLOOK ---------------------- At 1100 PM AST (0300 UTC), the center of Post-Tropical Cyclone Teddy was located near latitude 51.0 North, longitude 57.3 West based on the Marble Mountain, Newfoundland, radar and surface observations along the west coast of Newfoundland. The post-tropical cyclone is moving toward the north-northeast near 32 mph (52 km/h), and this general motion is expected to continue through Thursday. On the forecast track, the center of Teddy should move closer to the northwestern Newfoundland coast tonight and into the Labrador Sea on Thursday before merging with a larger extratropical low. Maximum sustained winds are near 50 mph (85 km/h) with higher gusts. Little change in strength is forecast before the system merges with the extratropical low on Thursday. Tropical-storm-force winds extend outward up to 205 miles (335 km) from the center. The estimated minimum central pressure is 975 mb (28.80 inches). By the Sea, Newfoundland (near the Cow Head Lighthouse) reported a barometric pressure of 979 mb (28.91 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 and on the web at https://www.hurricanes.gov/text/MIATCDAT5.shtml. 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. WIND: Gusty winds are possible along the western coast of Newfoundland tonight. NEXT ADVISORY ------------- This is the last public advisory issued by the National Hurricane Center on this system. For hazard information for Newfoundland and Labrador, please consult products issued by Environment Canada at weather.gc.ca/hurricane/index_e.html Additional information on the post-tropical cyclone can also be found in High Seas Forecasts issued by the National Weather Service, under AWIPS header NFDHSFAT1, WMO header FZNT01 KWBC, and online at ocean.weather.gov/shtml/NFDHSFAT1.php. $$ Forecaster Roberts
