Latest updates from the National Weather Service

Southern Connecticut

A flash flood watch is in effect through Thursday afternoon. The heaviest of the rain showers are expected late this afternoon through tonight. The rainfall should begin to taper off Thursday morning into the early afternoon from west to east. A widespread 3 to 6 inches of rain is forecast with locally higher amounts likely. This rainfall combined with wet antecedent conditions will likely lead to flash flooding. Flooding of fast responding rivers and streams is likely, with potential flooding of main stem rivers as well that could linger into the day Thursday.

Hartford CT-Tolland CT-Windham CT

A flash flood watch is in effect until Thursday afternoon. Widespread 3 to 5 inches of rain expected, with isolated amounts up to 7 or 8 inches not out of the question. This will bring the potential for "rare high impact type of flooding to southern New England."

"The potential for very significant urban and small stream flash flooding exists as well as the possibility of significant river flooding," the weather service said. "Some roads may become flooded and impossible with perhaps even few road washouts. While the axis of heaviest rainfall remains uncertain, areas near and south of the Massachusetts turnpike appear to be at greatest risk."

Litchfield County

A flash flood watch remains in effect through Thursday afternoon. Rainfall rates exceeding one inch per hour at times are possible tonight. Total rainfall amounts are expected to range between 3 and 6 inches which will likely result in flash flooding, especially in urban, low-lying and poor drainage areas.

Significant flash flooding will be possible, especially across portions of Ulster, Dutchess and Litchfield counties tonight, the weather service said. Some rivers are expected to rise and may overflow their banks leading to additional flooding.

Major flooding concern

The National Weather Service has issued a flood warning for the Housatonic River At Stevenson Dam from this afternoon until further notice. "The river is expected to rise above flood stage this afternoon and continue rising to a crest of 13.9 feet tomorrow morning...."

If the river reaches 15 feet that could impact "numerous homes in the Maples area of Shelton," the weather service said.
