More than 70 homes have been flooded by torrential rainstorms.
More flash floods are expected across the Midlands
The village of Albrighton, in Shropshire, was completely cut off when roads in and out were flooded. Water levels rose to nearly 4ft (1.2m).
Shropshire Fire and Rescue Service received about 100 calls between 1900 and 2355 BST, but crews were unable to do much until the water subsided.
Residents are now assessing the damage to their homes. Two schools are closed on Wednesday.
It is thought Albrighton Junior School and Birchfield Preparatory School for Boys will reopen on Thursday.
Cars have also been left stranded on the A41 in Cosford.
Residents said the A41 "was like a river" and reported seeing manhole covers moved by the force of water.
A spokesman for Shropshire Fire and Rescue Service said water levels had now subsided.

"It was just flash flooding and the water has subsided now.
"We got about 100 calls - cars were submerged and homes flooded.
"We have set procedures in place but what can you do when that happens - we could do about as much as King Canute could."
The Met Office said the heatwave was expected to end within the next 36 - 48 hours and would go out "with a bang".
More flash floods are expected across the Midlands on Wednesday.
