1. While the center of Teddy is forecast to move east of Bermudalate Sunday or Monday, tropical storm conditions are likely on theisland beginning Sunday evening.

2. Teddy is expected to transition to a powerful post-tropicalcyclone as it moves near or over portions of Atlantic Canada earlynext week, where there is an increasing risk of direct impacts fromwind, rain, and storm surge. Residents there should closely monitorthe progress of Teddy and updates to the forecast.

3. Large swells produced by Teddy are expected to affect portionsof the Leeward Islands, the Greater Antilles, the Bahamas, Bermuda,the east coast of the United States, and Atlantic Canada during thenext few days. These swells could cause life-threatening surf andrip current conditions.

CHANGES WITH THIS ADVISORY:

None.

SUMMARY OF WATCHES AND WARNINGS IN EFFECT:

A Tropical Storm Warning is in effect for...
- Bermuda

A Tropical Storm Warning means that tropical storm conditions are expected within the warning area, generally within 36 hours.

For storm information specific to your area, please monitor products issued by your national meteorological service.

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 affect Bermuda as early as tonight and could linger into Monday night.

SURF: Large swells generated by Teddy are affecting the Lesser Antilles, the Greater Antilles, the Bahamas, Bermuda, 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.

At 200 AM AST (0600 UTC), the center of Hurricane Teddy was located near latitude 27.6 North, longitude 61.6 West. Teddy is moving toward the northwest near 13 mph (20 km/h), and this general motion is expected to continue this morning. A turn toward the north is expected by tonight followed by a faster northward motion on Monday. On the forecast track, Teddy will approach Bermuda on Sunday night, and the center will pass just east of the island Monday morning.

Maximum sustained winds are near 115 mph (185 km/h) with higher gusts. Teddy is a category 3 hurricane on the SaffirSimpson Hurricane Wind Scale. Slow weakening is expected beginning later today.

Teddy is a large hurricane. Hurricaneforce winds extend outward up to 60 miles (95 km) from the center and tropicalstormforce winds extend outward up to 255 miles (405 km). Teddy's wind field is likely to become even larger over the next few days. NOAA buoy 41049 recently reported sustained winds of 54 mph (87 km/h) and a gust to 63 mph (101 km/h) about 85 miles (137 km) west of the center of Teddy.

The estimated minimum central pressure is 956 mb (28.23 inches).

Some convective cells have been developing within Teddy's large outer eye, and it is possible that this convection is forming an inner eyewall. In any event, observations from an Air Force Hurricane Hunter aircraft indicate that the maximum winds have decreased slightly, to near 100 kt. The hurricane is expected to remain in a low shear environment until tomorrow evening, and to more or less maintain its intensity for 12-24 hours. Thereafter, increasing shear associated with an upper-level trough to the west should cause weakening. Although the shear is predicted by the global models to become fairly strong after 48 hours, the system has a a very large and intense circulation so only slow weakening is expected. By 72 hours, Teddy should merge with a frontal zone to the east of New England and become a strong extratropical cyclone. The official intensity forecast is close to the model consensus.

The system's wind field will likely become even larger as the wind field of Teddy interacts within a high pressure system behind a cold front during the next few days. This could prolong the period of strong winds over Bermuda into Monday night.Teddy continues on a general northwestward track or about 315/11 kt. The hurricane should move on the western side of a subtropical high pressure area for the next day or so, and then begin to accelerate northward ahead of a strong mid-tropospheric trough that develops into a cutoff low off the northeast U.S. coast in a couple of days. The interaction of Teddy with this low will likely result in a slight leftward bend of the track around days 2-3. In 4-5 days, post-tropical Teddy is likely to turn north-northeastward to northeastward in the flow on the east side of a broad 500 mb trough. The official track forecast is a blend of the simple and corrected dynamical model consensus predictions.The extent of 12-foot or higher seas associated with Teddy continues to increase.
