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 expected to reach the Lesser Antilles and the northeastern coast of South America today should spread westward to the Greater Antilles, the Bahamas, and Bermuda by Friday. These swells are likely to cause lifethreatening surf and rip current conditions. Please consult products from your local weather office.

At 500 AM AST (0900 UTC), the eye of Hurricane Teddy was located near latitude 15.8 North, longitude 49.0 West. Teddy is moving toward the northwest near 12 mph (19 km/h). This general motion is forecast to continue for the next few days.

Maximum sustained winds have increased to near 100 mph (155 km/h) with higher gusts. Some strengthening is forecast during the next few days, and Teddy is likely to become a major hurricane later today and could reach category 4 strength on Thursday.

Hurricaneforce winds extend outward up to 25 miles (35 km) from the center and tropicalstormforce winds extend outward up to 175 miles (280 km).

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

continues to quickly intensify. The latest satellite images shows that a ragged eye is present, although microwave images show it is closed in the low-levels. Satellite intensity estimates earlier were between 77- 90 kt, and the initial wind speed is set to 85 with the increasing organization. The environment appears to be ripe for rapid intensification with light shear, warm water, and a solid ring present on overnight 37 GHz microwave data. Thus a 30-kt wind increase will be forecast for the first 24 hours from the 6Z initial wind speed of 80 kt. After that time, there could be an increase in shear from the mid-oceanic trough, which should level off the wind speed, along with possibly an increase in mid-level dry air. At long range, Teddy could also be affected by the cold wake from Paulette. The intensity forecast is also uncertain considering the guidance is still catching up to the higher current intensity, but most everything shows a large major hurricane for the bulk of the forecast period, and so does the official forecast. Teddy is moving northwestward at about 10 kt. A mid-tropospheric high should steer the hurricane in that general direction and speed throughout the forecast period until early next week when a turn to the north-northwest is possible ahead of a mid-latitude trough. The biggest change to note that guidance has almost unanimously shifted westward at long range, seemingly due to a stronger central Atlantic ridge, and the NHC forecast is also moved in that direction. Unfortunately, this change does increase the threat to Bermuda, which was just hit by Hurricane Paulette, but remember the average track error at 5 days is roughly 200 miles.
