Hurricane Isaias is closing in on the northern Gulf Coast as a major hurricane, with forecasters expecting landfall late tonight between Alabama and the western Florida Panhandle. Maximum sustained winds have reached about 120 miles per hour, making Isaias a Category 3 storm, and officials are warning that the most dangerous conditions will arrive well before the center crosses the shoreline.
Heavy rain bands are already pushing onshore, with gusts above 40 miles per hour reported along the coast and stronger winds measured near the eyewall. A tornado watch is in effect until this evening for the Florida Panhandle, extreme southern Georgia and southeast Alabama, as the storm’s outer bands spin up quick-hitting tornadoes with little warning. Life-threatening storm surge is expected along low-lying coastal roads, bays and sounds as onshore winds strengthen through the afternoon.
State emergency teams, search-and-rescue units and power restoration crews have been staged across vulnerable northern counties, according to officials in Florida. Evacuation traffic clogged Interstate 10 in Alabama’s Baldwin County overnight as residents moved inland. Forecasters stress that official landfall — the moment the surface center of the eye crosses the coast — is a technical milestone, not the start of danger, because the eyewall’s worst winds and surge extend dozens of miles outward.
Isaias is expected to spread heavy rain and wind inland over the Southeast through the weekend. Residents in the warning area are being urged to finish preparations immediately, keep multiple ways to receive alerts, and move to a safe room if a tornado warning is issued for their area. This story is developing and will be updated as conditions change.
How to read the storm signals
Hurricane categories describe wind, not total danger. The Saffir-Simpson scale runs from Category 1 to Category 5 based on maximum sustained winds, with Category 3 and above classed as major hurricanes. Winds at that level can damage roofs, snap trees and cut power across wide areas, but the deadliest threats from a Gulf storm are often water and brief, fast-moving tornadoes rather than the headline wind number alone. Keeping those hazards separate helps explain why officials warn about places well away from where the center eventually crosses the coast.
Storm surge is the abnormal rise of water pushed ashore by wind. It builds over hours, funnels into bays, sounds and river mouths, and can flood roads that are needed for evacuation long before the eyewall arrives. Rain bands ahead of the center add a second water risk, with streets and low ground flooding from rainfall even where surge stays limited. Together, wind, surge and rain explain why conditions deteriorate in stages and why waiting for the moment of landfall is waiting too long.
Tornado watches and warnings mean different things. A watch means conditions favor tornado formation across a broad area, so residents should know where they will shelter and keep alerts turned on. A warning means a tornado has been spotted or indicated by radar for a specific area, and shelter should happen immediately. The quick-hitting tornadoes in outer rain bands can form with short lead times, which is why forecasters emphasize having multiple ways to receive warnings, including a phone, a weather radio and local broadcast alerts.
Staying safe as conditions deteriorate
Preparation in the final hours is mostly about position and information. People in the warning area are safest away from windows, in an interior room on the lowest floor that is not at risk of flooding, with shoes, a flashlight, medications and charged phones close at hand. Mobile homes and vehicles are unsafe shelter in high wind or tornadoes. Those who have been told to evacuate should leave early, because water-covered roads and fallen debris can close routes that were passable an hour earlier.
Travel during the storm itself carries its own dangers. A small amount of moving water can make a vehicle impossible to control, and downed power lines may be hidden in standing water. After winds ease, hazards remain: unstable trees, damaged structures, contaminated floodwater and generators used indoors, which can produce lethal carbon monoxide. Official guidance consistently stresses staying put until local authorities confirm that roads and neighborhoods are safe to re-enter, and treating every downed line as energized. As Isaias moves inland, those habits, along with prompt attention to official updates, remain the most reliable protection available.
