1. The center of Teddy is forecast to move east of Bermuda on Monday. Tropical storm conditions are likely on the island beginning this evening and could continue into Monday evening.

2. Teddy is expected to transition to a powerful post-tropical cyclone as it moves near or over portions of Atlantic Canada early next week, where there is an increasing risk of direct impacts from wind, rain, and storm surge. Residents there should closely monitor the progress of Teddy and updates to the forecast.

3. Large swells produced by Teddy are expected to affect portions of the Leeward Islands, the Greater Antilles, the Bahamas, Bermuda, the east coast of the United States, and Atlantic Canada during the next few days. These swells could cause life-threatening surf and rip 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. Interests in Atlantic Canada should closely monitor the progress of Teddy.

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 tonight and could continue 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 1100 AM AST (1500 UTC), the center of Hurricane Teddy was located near latitude 28.3 North, longitude 62.8 West. Teddy is moving toward the northwest near 9 mph (15 km/h). A turn toward the north is expected tonight and then Teddy is forecast to continue generally northward for another couple days. On the forecast track, Teddy will approach Bermuda tonight, and the center should pass east of the island Monday morning. Teddy should be approaching Nova Scotia on Wednesday.

Maximum sustained winds are near 105 mph (165 km/h) with higher gusts. Little change in strength is expected today. Teddy is expected to remain a large and powerful hurricane through Monday, then become a strong posttropical cyclone on Tuesday.

Teddy remains a large hurricane. Hurricaneforce winds extend outward up to 80 miles (130 km) from the center and tropicalstormforce winds extend outward up to 205 miles (335 km). The estimated minimum central pressure is 964 mb (28.47 inches).

The satellite signature of Teddy has degraded from an eye pattern overnight into a central dense overcast this morning. Air Force Reserve Hurricane Hunter aircraft data indicate that the hurricane has weakened, and the initial wind speed is set to 90 kt, perhaps generously. The aircraft data does still show that Teddy remains a large hurricane, with hurricane-force winds extending outward in the northeastward quadrant to about 70 n mi.While the forecast intensity does not change much over the next couple of days, the hurricane should undergo significant changes during that time. Teddy should not lose any more strength by late today due to favorable positioning with an approaching trough, and the gale-force winds should greatly expand due to this trough interaction. In 2 or 3 days, after the system occludes and becomes post-tropical, the cyclone should weaken because of a loss of extratropical forcing while over the cooler water south of Nova Scotia. Eventually Teddy will probably get absorbed by a larger extratropical low around day 5. Model guidance is fairly tightly packed around the official wind forecast, which leans on the global models given the substantial extratropical contributions, plus or minus 5 kt throughout the forecast period.The hurricane has resumed a northwestward motion or 320/8 kt. Teddy is likely to turn northward today and north-northeastward tomorrow due to the aforementioned trough. By early Tuesday, the cyclone should turn back to the north-northwest as it rotates around the same trough, then turn northeastward early Wednesday ahead of yet another trough moving into from eastern Canada. Although the forecast evolution is complex, model guidance is in remarkably good agreement, and no substantial changes were made to the previous forecast. Regardless of the details, every model has a rather large and strong post-tropical cyclone south of Nova Scotia in about 3 days.
