SURF: Large swells generated by Tropical Storm Teddy are expected to reach the Lesser Antilles and the northeastern coast of South America on Wednesday. These swells are likely to cause life threatening surf and rip current conditions. Please consult products from your local weather office.

At 1100 PM AST (0300 UTC), the center of Tropical Storm Teddy was located near latitude 13.2 North, longitude 45.0 West. Teddy is moving toward the west near 13 mph (20 km/h). A westnorthwestward motion at a slower forward speed is expected overnight through Tuesday night, followed by a northwestward motion Wednesday and Thursday.

Maximum sustained winds remain near 50 mph (85 km/h) with higher gusts. Strengthening is forecast for the next several days. Teddy is expected to become a hurricane Tuesday and could reach major hurricane strength on Thursday.

Tropicalstormforce winds extend outward up to 115 miles (185 km) from the center.

The estimated minimum central pressure is 1002 mb (29.59 inches).

is displaying some mixed signals this evening. On one hand, satellite imagery shows an improving cloud pattern, with increasing central convection and a large curved band on the southern side of the circulation. The latest TAFB/SAB Dvorak estimates have increased to 55 kt on this basis. Scatterometer data, surprisingly, only shows 35-40 kt. The initial wind speed remains 45 kt as a blend of that data, assuming the typical undersampling from ASCAT, but there is a fair bit of uncertainty in the current wind speed. Teddy should have several days in a low or moderate shear environment over warm waters to intensify. All guidance responds to this forcing by showing Teddy near major hurricane strength in a few days, with the biggest disagreement being how fast it gets there. The new forecast is similar to the previous one, leaning toward the NOAA corrected-consensus guidance HCCA. Teddy is moving about the same as before, or 280/11 kt. No substantial changes were made to the forecast track with the storm in a seemingly stable steering current provided by a deep-layer ridge over the central Atlantic. Teddy should turn west-northwestward overnight and then northwestward on Wednesday through the end of the forecast while it moves on the southwestern flank of the ridge. Model guidance is in excellent agreement, with only some minor speed differences. The NHC track prediction is basically on top of the previous one and the consensus aids.
