The storm, described as the first hurricane of the Atlantic season, is forecast to strengthen rapidly before reaching the northern Gulf Coast late Friday or early Saturday.
Forecasters warned that the Florida Panhandle, southern Alabama and southern Mississippi could experience life-threatening coastal flooding, damaging winds and widespread power outages.
According to the National Hurricane Center in Miami, Isaias had maximum sustained winds of approximately 75 miles per hour early Thursday and was moving east-northeast at 9 miles per hour.
The hurricane was located about 445 miles south-southwest of the mouth of the Mississippi River.
Heavy rainfall associated with the storm could also trigger flooding across inland communities, with impacts potentially extending into the Tennessee Valley throughout the weekend.
Authorities across the Gulf Coast have begun implementing emergency measures to protect residents and critical infrastructure.
In Florida, at least four school districts canceled classes ahead of the storm, while officials in Okaloosa County ordered mandatory evacuations for some vulnerable coastal communities.
Governors in Florida and Alabama also declared states of emergency across dozens of counties, allowing authorities to mobilize resources and coordinate disaster-response operations.
The approaching hurricane has also disrupted offshore energy operations, with some Gulf of Mexico oil wells temporarily suspending production as a precaution.
Meanwhile, the National Weather Service warned communities stretching from Ocean Springs, Mississippi, to Gulf County, Florida, to prepare for the possibility of prolonged electricity outages.
Emergency officials are urging residents in vulnerable areas to follow evacuation orders, secure their properties and prepare essential supplies before conditions deteriorate.
With the hurricane expected to intensify before landfall, authorities remain concerned about the combined effects of storm surge, damaging winds and heavy rainfall across the northern Gulf Coast.
