At least 21 dead in Memorial Day storms that devastated several US states

A series of powerful storms swept over the central and southern U.S. over the Memorial Day holiday weekend, killing at least 21 people and leaving a wide trail of destroyed homes, businesses and power outages.
The destructive storms caused deaths in Texas, Oklahoma, Arkansas and Kentucky and were just north of an oppressive, early season heat wave setting records from south Texas to Florida.
Forecasters said the severe weather could shift to the East Coast later Monday and warned millions of people outdoors for the holiday to watch the skies.
Kentucky Gov. Andy Beshear, who earlier declared a state of emergency, said at a Monday press conference that four people had died in four different counties.
The death toll of 21 also included seven deaths in Cooke County, Texas, from a Saturday tornado that tore through a mobile home park, officials said, and eight deaths across Arkansas.
