Northeast U.S. flooding of October 2005

In October 2005, remnants of Tropical Storm Tammy and Subtropical Depression Twenty-Two merged with incoming continental cold fronts to produce torrential rains over interior New England, as well as over parts of New Jersey and New York. Particularly hard hit was the state of New Hampshire, which saw roads and bridges wiped out, several reported deaths, and whole buildings destroyed. Rain lingered over some areas for several weeks. Rainfall from both rain events totaled well over 20 inches (510 mm) in some areas.

With 14.94 inches (379 mm) of rain in October 2005, T. F. Green Airport recorded its wettest month ever. During October 13–15, rainfall was heaviest in central and eastern Massachusetts and Rhode Island. The NWS reported rainfall amounts of 4 to 7 inches (100 to 175 mm) in central and eastern Massachusetts and 7 to 9 inches (175 to 225 mm) in Rhode Island. A state of emergency was declared for the state, and thousands were without power. At least 100 residents were evacuated after swift rises in local rivers, and Red Cross shelters were set up throughout the state. The Pawtuxet River, at Cranston and Warwick, recorded its second-worst flood, at a stage of 13.68 feet (4.17 m). The Blackstone River, at Woonsocket, also recorded its second-worst flood, at a stage of 15.34 feet (4.68 m). The Woonasquatucket River in Providence and Central Falls recorded a new flood record, at 8.3 feet (2.53 m). Damage in Rhode Island totaled $1.6 million (2005 USD).
