Greenwich is cleaning up after Sunday's storm dumped nearly 4 inches of rain, closing roads, flooding neighborhoods and triggering a flash flood warning across southern Fairfield County.

National Weather Service data showed Greenwich received 3.78 inches of rain on Sunday, Sept. 13, according to CT Insider. Nearby Fairfield recorded 5.95 inches and Stamford 5.14 inches. Branford, on the shoreline, topped the state at 6.98 inches.

Gov. Ned Lamont called the storm a "rain bomb" at a Monday, Sept. 14, news conference at the state Capitol.

"Five, seven, nine inches [of rain] in a very limited period of time," Lamont said, according to CT Insider. "That's what caused severe flooding that overwhelms our stormwater drainage systems."

Fairfield County was hit hardest. As we reported Sunday, Greenwich police closed six roads by 9:30 a.m., including Riverside Lane, Henry Street, East Weaver Street and both ends of Benjamin Street. Sound Beach Avenue was partially closed. Hazards were also reported at Bolling Place and Jones Park Drive.

Flooding on I-95 southbound between exits 6 and 5 reduced traffic to one lane, Patch reported. In Old Greenwich, floodwaters surrounded Binney Park.

The NWS flash flood warning for Greenwich expired at 11:30 a.m. Sunday. A flood watch for the lower portion of the state remained until 2 p.m.

State Emergency Management Director William Turner said Monday that no injuries or fatalities were reported statewide, though many people had to be rescued from vehicles. More than 100 state Department of Transportation trucks and hundreds of employees worked around the clock Sunday to clear debris and reopen roads, according to CT Insider. DOT Deputy Commissioner Laoise King said no permanent damage to state infrastructure was found, though a DOT facility in Westport took on six feet of water in its yard and four feet inside the building.

Eversource reported 474 remaining outages as of 1 p.m. Monday. United Illuminating reported 10. Late Sunday night, the two utilities had reported nearly 2,000 combined outages. Metro-North and Amtrak service returned to normal Monday.

First Selectman Fred Camillo urged Greenwich residents Sunday to stay off roads, particularly in low-lying and flood-prone areas, according to a town alert reported by Greenwich Free Press.

Rivers across Connecticut continued to run high Monday, and forecasters expected another band of rain to move through the state before clearing, according to WTNH. Turner encouraged residents who experienced home damage to fill out a damage survey issued by the state Department of Emergency Services and Public Protection (DESPP), which the state will use to determine eligibility for federal relief.
