​

Hurricane Teddy
A Tropical Storm Warning is in effect for Bermuda.

​

Maximum sustained winds are near 205 km/h with higher gusts. Some fluctuations in intensity are likely today. A more pronounced decrease in Teddy's maximum winds is forecast to begin on Sunday, but the wind field of the hurricane is forecast to increase substantially at the same time.

Tropical storm conditions are expected to affect Bermuda and the nearby waters beginning Sunday afternoon or evening. These conditions may linger through most of the day Monday.

Large swells generated by Teddy are affecting the Lesser Antilles, the Greater Antilles, the Bahamas, and Bermuda. Swells from Teddy will begin affecting most of the east coast of the United States later today and will reach Atlantic Canada by early Sunday. These swells are likely to cause life-threatening surf and rip current conditions.

Tropical Storm Wilfred
There are no coastal watches or warnings in effect.

Maximum sustained winds are near 65 km/h with higher gusts. Small fluctuations in intensity are possible over the weekend. A general weakening trend should begin by late Sunday and Wilfred is forecast to become a remnant low in a few days.

Tropical Storm Beta
A Storm Surge Watch is in effect for
Port Mansfield, TX to Cameron, LA including Baffin Bay, Corpus
Christi Bay, Copano Bay, Aransas Bay, San Antonio Bay, Matagorda Bay, Galveston Bay, Sabine Lake and Calcasieu Lake

​

A Hurricane Watch is in effect for
Port Aransas Texas to High Island Texas

A Tropical Storm Watch is in effect for
South of Port Aransas Texas to the Mouth of the Rio Grande
East of High Island Texas to Morgan City Louisiana

Maximum sustained winds are near 95 km/h with higher gusts. Slow strengthening is forecast, and Beta is expected to become a hurricane on Sunday.

The combination of a dangerous storm surge and the tide will cause normally dry areas near the coast to be flooded by rising waters moving inland from the shoreline. The water could reach the following heights above ground somewhere in the indicated areas if the peak surge occurs at the time of high tide
Port Mansfield, TX to Cameron, LA including Baffin Bay, Corpus Christi Bay, Copano Bay, Aransas Bay, San Antonio Bay, Matagorda Bay, Galveston Bay, Sabine Lake, and Calcasieu Lake...2-4 ft
Mouth of the Rio Grande, TX to Port Mansfield, TX...1-3 ft
Cameron, LA to Morgan City, LA including Vermilion Bay...1-3 ft

Hurricane conditions are possible within the hurricane watch area by late Monday or Monday night, with tropical storm conditions possible by late Sunday.  Tropical storm conditions are possible within the tropical storm watch area along the upper Texas and southwestern Louisiana coast as early as tonight.  Tropical storm conditions are possible within the tropical storm watch area along the south Texas coast late Sunday.

There is an increasing risk of significant rainfall and flooding along the Texas and Louisiana coasts Sunday through at least the middle of next week as Beta is forecast to move slowly near the Texas coast. For additional information, see products from your local National Weather Service office.

Swells are expected to increase and reach the coast of Texas and the Gulf Coast of Mexico later today, generated by a combination of Beta and a cold front entering the northern Gulf of Mexico.  These swells are likely to cause life-threatening surf and rip current conditions.
