The National Weather Service has issued a severe thunderstorm warning until 6:30 a.m. for Ripley and Dearborn counties in Southeast Indiana, northern Boone County in Northern Kentucky and western Hamilton and southwestern Butler counties in Southwest Ohio.

More than 100 million people in the U.S. will be in the path of an intense March storm starting Friday as the sprawling multi-day system threatens fires, blizzards, tornadoes, and flooding as it tracks eastward across the Great Plains.

"The storms which prompted the warning have weakened below severe limits, and no longer pose an immediate threat to life or property. Therefore, the warning will be allowed to expire. However, gusty winds are still possible with these thunderstorms," states the NWS Los Angeles/Oxnard CA. The warning is in effect until 9:30 p.m.
