Gov. Ned Lamont said he has been in contact with mayors and first selectmen of towns that have been affected by the flooding.
“This was an historic storm in some areas of Connecticut. Once daylight occurs, crews will be out to survey damage and begin clean-up. If you live in the western portion of Connecticut, we are urging you to stay home if you can until the flooding has receded, and definitely do not ever attempt to drive through any flooded roads. A good number of roads in the western portion of the state are closed and are expected to remain closed for an extended period," Gov. Lamont said in a statement.
More rain is expected overnight, keeping the risk for flash flooding higher with the potential for some downpours.
Humidity will also be on the higher side through Monday with dew point temperatures in the upper 60s to 70 degrees. Monday will feature dew point temperatures into the 70s after the warm front moves through during the early morning hours.
A cold front will move through the state Monday evening with another round of showers and storms.
Behind the front, much less humidity and plenty of sunshine moves in for Tuesday and most of next week.
