Downpours will spread across the South and Appalachians as Hurricane Isaias’ remnants head north after landing in Florida Friday night, knocking out power to hundreds of thousands of residents across three states.

There’s a moderate risk of heavy rainfall across parts of western North Carolina south to Georgia Saturday, the U.S. Weather Prediction Center said. The region was devastated when Hurricane Helene swept through in 2024 — flooding cities, blocking roads, and killing at least 249 people nationally.

Isaias shouldn’t bring the destructive force Helene unleashed, said Marc Chenard, a senior branch forecaster at the U.S. Weather Prediction Center. “We still have to keep an eye on the southern Appalachians. It still looks like there could be some significant impacts there through the day.”

Isaias will put about 12.6 million people from Florida to Virginia at a level two risk for severe thunderstorms, which can bring downpours and spawn tornadoes, through the weekend, the U.S. Storm Prediction Center said.

The storm also hit energy production across the Gulf of Mexico during the week and knocked out power to more than 875,000 homes and businesses as of Saturday morning, according to PowerOutage.com.

Oil output in the Gulf of Mexico plummeted as the storm approached the U.S. coast, companies evacuated crews from platforms as a precaution, and drillers sailed rigs out of its path.

The Category 2 storm made landfall at 8:30 p.m. near Destin, Florida, with top winds of 105 miles (169 kilometers) an hour. It quickly degraded into a post-tropical cyclone, according to the U.S. National Hurricane Center.

The first hurricane to hit the U.S. in almost two years will bring widespread rain of as much as 8 inches (20 centimeters) across the region, with as much as 15 inches (38 centimeters) seen in some localized areas.

Tropical storm conditions will likely continue Saturday morning as the storm system tracks north across Alabama and into the Tennessee and Ohio valleys throughout the day and into Sunday, forecasters said. The storm system is expected to bring heavy rain and could spawn tornadoes as far north as the Carolinas.

While the tropical risks subside in the east, western Mexico and the Southwest face twin threats from Tropical Storm Rachel and Hurricane Simon.

Rachel is forecast to strike near the U.S.-Mexico border in northern Baja California late Saturday and then bring flooding rains across the Southwest, including parts of California, Arizona and Nevada, the U.S. National Hurricane Center said.

There are rare tropical storm watches up across Southern California, including for San Diego.

Further south, Simon is forecast to strike near Manzanillo, Mexico, the country’s busiest Pacific port, overnight as Category 4 hurricane on the five-step, Saffir-Simpson scale, packing winds of 155 miles per hour. As much as 20 inches (51 centimeters) of rain may fall widely, with isolated spots getting up to 40 inches (102 centimeters).

“Catastrophic wind and life-threatening storm surge impacts are likely along a portion of the west-central coast of Mexico,” the U.S. hurricane center said. The rains “will produce life-threatening flooding and mudslides.”
