Tropical Update
Helene becomes a category 2 hurricane with significant additional strengthening expected before landfall in Florida. On the forecast track, Helene will move across the eastern Gulf of Mexico today and cross the Florida Big Bend coast this evening or early Friday morning. After landfall, Helene is expected to turn northwest and slow down over the Tennessee Valley on Friday and Saturday.
Maximum sustained winds have increased to near 100 mph with higher gusts. Additional strengthening is forecast, and Helene is expected to be a major hurricane when it reaches the Florida Big Bend coast this evening. Weakening is expected after landfall.
Hurricane-force winds extend outward up to 60 miles from the center and tropical-storm-force winds extend outward up to 345 miles.
Tropical Storm Isaac has formed in the open central subtropical Atlantic. A general east to ENE motion is anticipated over the next several days. Some strengthening is forecast during the next couple of days and Isaac could be near hurricane intensity by the end of the week.
Tracking a broad area of low pressure along a tropical wave located several hundred miles west of the Cabo Verde Islands.
