The episode as NWS BTV wrote it up.
Low pressure moved northeast across New England during the afternoon of April 28th through midday on the 29th. One and a half to 3 inches of rain fell across the Passumpsic River Valley in Caledonia county, Vermont during the 28th into the 29th. This heavy rainfall combined with melting snow caused several smaller streams and rivers in Caledonia county, including Millers Run and the East Branch of the Passumpsic to flood and led to portions of the Passumpsic River in Lyndonville to flood as well. Flooding occurred from midday on the 29th through the early morning hours of the 30th and was mainly confined to state and local roads with a few flooded house trailers in Lyndonville.
