VIDEO: In two places on the same night, the storm that deluged the Northeast this weekend dumped rain at or near rates that should be expected only once in a thousand years.
The storm killed at least three people and caused widespread flooding. It dropped about 10 inches of rain over 12 hours on Sunday in parts of Connecticut including Oxford and Southbury. About 35 miles away, about 6.7 inches of rain fell in three hours on Sunday night in Stony Brook, New York. Both are measures that would have roughly a 0.1% chance of happening in a year, according to federal rainfall probability data.
“There were two areas that got sort of equally extreme rainfall, and they didn’t happen at the same time,” said Nick Bassill, director of the state weather risk communication center at the University of Albany in New York.
