The catastrophic flood devastating Louisiana is now the worst natural disaster to strike the United States sinceHurricane Sandy four years ago, the Red Cross said.
"Thousands of people in Louisiana have lost everything they own and need our help now," said Brad Kieserman, the Red Cross' vice president of disaster services operations and logistics.
"This disaster is the worst to hit the United States since Superstorm Sandy, and we anticipate it will cost at least $30 million -- a number which may grow as we learn more about the scope and magnitude of the devastation."
The calamity struck quickly and ferociously. In one part of Livingston Parish, more than 31 inches of rain fell in 15 hours.
Gov. John Bel Edwards said at least 40,000 homes have suffered at least some damage. It's not clear how many are uninhabitable.
He called on volunteers to help clean out mud from homes.
"Not everyone can do this on their own," the governor said. He said anyone interested in helping can visit VolunteerLouisiana.gov.
The Red Cross has also asked for donations to help more than 7,000 people in emergency shelters.
