Hurricane Isaias continues to intensify over the Gulf of Mexico as it moves toward the northern Gulf Coast, where forecasters warn of dangerous winds, life-threatening storm surge, flooding rain, and isolated tornadoes beginning Friday and continuing into the weekend.
As of 7 p.m. CDT, the storm's center was located about 250 miles south-southwest of the Mississippi coast and was moving northeast at 13 mph. Forecasters expect Isaias to turn more northward on Friday and approach the northern Gulf Coast before making landfall late Friday or early Saturday.
The hurricane is packing sustained winds of 100 mph, making it a strong Category 2 storm. Additional strengthening is expected through early Friday, and Isaias is forecast to remain a dangerous hurricane as it nears the coast. Hurricane-force winds extend up to 15 miles from the center, while tropical-storm-force winds reach outward as far as 125 miles.
A Hurricane Warning remains in effect for portions of the northern Gulf Coast, where hurricane conditions are expected Friday night into early Saturday. Tropical storm conditions are expected to develop ahead of the storm's arrival.
Storm surge remains one of the greatest threats. Coastal communities from Mississippi to Florida's Panhandle could see water levels rise between 5 and 7 feet above normally dry ground, especially in areas where onshore winds coincide with high tide. Other sections of Florida's Gulf Coast could experience surge levels of 2 to 6 feet, accompanied by dangerous waves and coastal flooding.
Heavy rainfall is also expected across much of the Southeast. Forecasters predict widespread totals of 4 to 8 inches across southern Alabama, the Florida Panhandle, the Big Bend region, and southwest Georgia through the weekend. Some locations could see as much as 15 inches of rain, increasing the risk of flash flooding, urban flooding, and river flooding. Significant flooding impacts are possible, particularly across the Florida Panhandle and southern Alabama.
Farther east, portions of the Carolinas could receive 3 to 5 inches of rain, with isolated higher totals approaching 8 inches.
In addition to flooding concerns, isolated tornadoes may develop Friday night across coastal areas of Alabama, the Florida Panhandle, and southwestern Georgia. The tornado threat is expected to expand into parts of Alabama and Georgia on Saturday.
Dangerous surf and rip currents are also forecast along Gulf Coast beaches as swells generated by Isaias spread northward. Officials are urging residents and visitors to stay out of the water and closely monitor local forecasts and emergency instructions.
Residents across the Gulf Coast are being encouraged to complete storm preparations before conditions begin to deteriorate on Friday. Emergency management officials warn that travel could become hazardous as heavy rain, strong winds, and coastal flooding impact the region.
