They don't meet often; the last time was last summer, when the committee approved a new 24-hour rainfall record in New York: 13.57 inches on Long Island. Koch said it's likely that the Buffalo storm will break New York's 24-hour snow record. That record, 49 inches, was set in Watertown in November 1900, according to the National Climatic Data Center. Despite its rigid adherence to proper meteorological protocol, even the data center concedes there might be other records.
