Severe storms continue to wallop the U.S., including in Pensacola, Florida where historic flooding has swamped the region. In Escambia County, officials issued a state of emergency after over 200 mm of rain fell.  Rescue crews scrambled to reach stranded motorists and a search was underway for a missing driver who had called for emergency help Tuesday. An emergency management official asked drivers to stay off the roads for the next 24 hours. MORE
