Officials said the flooding damaged hundreds of homes, dozens of businesses and hundreds of vehicles causing millions in losses. Forty-five people and dozens of pets were rescued during the flooding, officials said.

"I promise you we're going to work together and find every available resource we can," said Murphy.
Families were trying to clean up as the rain continued to fall. Many have lost parts of their lives: appliances, photo albums, kids' toys and winter items stored in the basement that are now destroyed and coated in mud.
"We are devastated," Fran Richards said. "Everything in the basement flooded, cars floating, it's devastating."
The rain was even heavy enough to flood a Route 46 car dealership, sending vehicles floating like small icebergs.
