There are no coastal watches or warnings in effect.

There are no coastal watches or warnings in effect.

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 lifethreatening surf and rip current conditions. Please consult products from your local weather office.

At 1100 PM AST (0300 UTC), the center of Hurricane Teddy was located near latitude 17.8 North, longitude 51.5 West. Teddy is moving toward the northwest near 13 mph (20 km/h), and this general motion is expected to continue through the weekend.

Maximum sustained winds are near 90 mph (150 km/h) with higher gusts. Strengthening is forecast during the next couple of days, and Teddy could become a major hurricane Thursday night or Friday.

Hurricaneforce winds extend outward up to 35 miles (55 km) from the center and tropicalstormforce winds extend outward up to 255 miles (405 km).

The estimated minimum central pressure is 976 mb (28.82 inches).

Teddy has been a perplexing hurricane thus far. The infrared satellite presentation appears rather impressive, with the center embedded beneath a Central Dense Overcast with cloud tops as cold as -85 degrees Celsius. Despite the presentation, however, Dvorak estimates from TAFB and SAB are a consensus T4.5/77 kt, and objective estimates range between 70-75 kt. Teddy's initial intensity is therefore set just above these estimates at 80 kt. A recent ASCAT pass indicated that Teddy's center is a little farther to the southwest than previously estimated. However, the long-term motion remains toward the northwest (315/11 kt). The track forecast remains straightforward the the next 3 days, with the guidance in good agreement that a mid-tropospheric high over the central Atlantic will drive the hurricane northwestward toward the western Atlantic. There is a little more spread among the track models on days 4 and 5, related to timing differences on exactly where and how fast Teddy begins to recurve ahead of an approaching mid-latitude trough coming from the northeastern United States. The new NHC track forecast has been nudged westward during the first 3 days to account for the initial position adjustment, but otherwise it's still close to the previous prediction even with the increasing model spread on days 4 and 5. An upper-level trough situated to the northwest of Teddy is causing about 10-15 kt of deep-layer southwesterly shear over the hurricane, and some model analyses suggest that there could be stronger shear in a layer below the level of the upper-level outflow. The deep-layer shear is expected to increase a bit during the next day or so, but this should be offset by a favorable thermodynamic environment, allowing for some intensification during that time. The shear might relax by days 3 and 4, but then the thermodynamic environment becomes a little less conducive for strengthening. In particular, Teddy may move over the cold wake of Hurricane Paulette, and the SHIPS guidance indicates that relatively warm upper-level temperatures could be a negative factor. All that said, the NHC intensity forecast lies near the top end of the guidance envelope, showing Teddy peaking in intensity in a couple of days and then only gradually weakening through the end of the forecast period.
