What happened
The episode as NWS ALY wrote it up.
The remnants of tropical storm Allison joined forces with a slow moving cold front from the west, to produce torrential rainfall over much of Litchfield County on June 17. Between 2 and 6 inches of rain fell in a short time over the central and southeastern portions of the county, with the maximum amounts located near the East Aspetuck River Basin. The East Aspetuck River came out of its banks from New Preston south through the towns of Northville and New Milford. In New Milford, the river came up to the same level as a bridge on Welles Road. Some roads were flooded there as well. A large sinkhole developed in New Hartford due to the excessive rainfall. Roads washed out in the town of Bethlehem. In Woodbury, numerous small streams overflowed and roads flooded.
