SUNDAY FLOOD WARNING: In effect for Shelton, heavy rainfall possible

A Flood Warning has been issued for Shelton and Fairfield County for late this afternoon and early this evening.

This represents increased severity from a Flood Warning that had been in effect earlier Sunday by the National Weather Service (NWS).

The Flood Warning is in effect until 6:15 p.m. in Shelton, partly due to heavier rain expected in the next few hours. This mainly involves small streams rather than large rivers, such as the Housatonic. Waterways "will approach or exceed bank-full," the NWS said.

Be careful when driving

"A Flood Warning means that flooding is imminent or has been reported," the NWS said. "Stream rises will be slow and flash flooding is not expected."

The NWS warns people not to drive vehicles into locations where water covers the roadway. "The water depth may be too great to allow your car to cross safely," the NWS said.

Late thunderstorm possible

In Shelton, it's 44 degrees as of 4 p.m. Up to another three-quarters of an inch of rain could fall through about 3 a.m., the NWS said.

A thunderstorm could occur in the late evening. "Some of the storms could produce heavy rainfall," according to the NWS.

The overnight low should be around 34 degrees in Shelton, so it's unlikely any snow will fall and re-freezing in most parts of Shelton — depending on elevation — is unlikely as well.
