BREAKING: Massive Fire Breaks Out at Louisville GE Appliance Park

Emergency crews responded to a massive fire at General Electric's Appliance Park in Louisville, Kentucky, early Friday morning.

The fire occurred in Building 6 of the plant and was quickly evacuated, a MetroSafe spokeswoman told USA Today.

The cause of the fire was not immediately known.

Louisville, Kentucky, was inundated by heavy rain overnight Thursday, as severe weather broke out across the Ohio Valley. By Thursday morning, some roadways were under more than 12 inches of water.

The Louisville area is forecast to receive additional rounds of drenching rain on Friday, though the risk of damaging thunderstorms will diminish, according to Expert Meteorologist Alex Sosnowski.

"Enough additional rain can fall to cause more flooding problems. However the rain during the midday and afternoon will not be as intense as Thursday night," Sosnowski said.
