Summary: The National Hurricane Center (NHC) reported this morning that Hurricane Isaias continues to gain strength and is expected to make landfall along the U.S. Gulf Coast late Friday or early Saturday, threatening parts of Mississippi, Alabama, and the western part of the Florida Panhandle with heavy rain and wind. This system became the first hurricane of the 2026 Atlantic season after strengthening from a tropical storm late Wednesday night.
As of 11 am ET, the center of Hurricane Isaias was located 380 miles south of the mouth of the Mississippi River with maximum sustained winds of 85 mph (category 1). According to NHC, Isaias is moving toward the east-northeast near 10 mph. A turn toward the northeast is expected later today followed by a turn northward on Friday. Forecasters expect Isaias to make landfall along the U.S. northern Gulf Coast within the hurricane warning area late Friday or early Saturday.
Additional strengthening is expected through early Friday, with Isaias likely to remain a dangerous hurricane as it approaches the northern Gulf Coast Friday night. Strong, gusty winds could extend well inland after landfall as the storm’s wind field expands and its forward speed increases, the NHC stated in its forecast.
Starting Friday and through the weekend, Isaias is expected to produce rainfall amounts of 3 to 7 inches across the central U.S. Gulf Coast extending from far southeastern Louisiana to the Florida Big Bend region. Localized totals up to 15 inches are possible, particularly within banding across the Florida Panhandle and Big Bend, according to NHC. Rainfall amounts of 1 to 3 inches, with localized amounts up to 5 inches, are possible across much of the Southeast as far north as the Tennessee Valley and the Carolinas.
Flash flooding is possible across the region, with substantial impacts possible across much of southern Alabama and the Florida Panhandle into southwestern Georgia. River flooding is also expected, some of which could be significant. In addition, isolated tornadoes will be possible Friday night in coastal areas of Alabama and the Florida Panhandle and far southwestern Georgia. The tornado threat will continue Saturday for eastern Alabama, Georgia, and northern Florida. Lastly, portions of the Ohio Valley and Mid-Atlantic regions could also experience heavy rainfall from the storm as the weekend progresses.
Analyst Note: Isaias’ development into a hurricane Wednesday marked the latest date in 121 years for the Atlantic season’s first hurricane to develop, narrowly missing the record set on October 8, 1905, according to data from NOAA. In a typical Atlantic hurricane season, the hurricane center records an average of 14 named storms, seven hurricanes, and three major hurricanes.
Forecasters had expected Atlantic storm activity to remain below average this year, but the season has been even quieter than anticipated. Meteorologists largely attribute the subdued activity to the development of a strong El Niño over the summer, which is typically associated with cooler Atlantic waters and increased wind shear—both of which can hinder the development and strengthening of tropical systems. Meanwhile, the Pacific has experienced an unusually active stretch of hurricanes.
Nevertheless, while both NOAA and the Colorado State University forecast below average activity for the 2026 Atlantic hurricane season, they emphasize that it only takes one landfall making system to make it an active season for the communities in the path.
