Steady rain that fell Sunday added up to a new daily record at Buffalo Niagara International Airport, where official measurements are made.
Through midnight, 2.25 inches was recorded, according to Dave Thomas, a meteorologist with the National Weather Service in Buffalo. The previous record for May 31 was 1.30 inches in 1889.
“It was a slow, steady rainfall; a good rainfall,” Thomas said.
And that daily total represents the second rainiest day ever in the month of May, going back to the start of recordkeeping in 1871. The daily record, for the entire month, is the 3.41 inches that fell on May 19, 1986.
“It’s very rare to get this much rain and not have significant flooding problems,” Thomas said.
Flash flooding that occurred Saturday in the Wyoming County Village of Warsaw came after 3.5 inches of rain fell within two hours during heavy thunderstorms, Thomas said.
“That much rain that quickly – that’s what produced the flash flooding,” Thomas said. “They are probably in the neighborhood of 4 inches for the weekend.”
