Connecticut's five members of Congress and two Senators have sent a letter to FEMA supporting the state's appeal of the agency's refusal to provide disaster aid to individual property owners, as well as to the towns of Bridgewater, New Milford and Roxbury, for recovery from the May 15th supercell thunderstorms.  The storms included tornadoes, a waterspout, tennis ball-sized hail and a straight-line windstorm - resulting in power outages, damage to homes and personal property, and the creation of massive amounts of debris.   Individual homeowners now face costs of up to $70,000 each in debris removal and tree and structural damage.  They say scarce municipal resources were exhausted to provide emergency services and to clear debris, leading to unanticipated costs and strained budgets.
