4 Inches Of Rain, Flooding Concerns Forecast: Timeline, New Details Released

CONNECTICUT — A flood watch has been issued statewide except for Litchfield County as 1-3 inches of rain is forecast to fall beginning Wednesday afternoon and continuing into Thursday.

And then another rainstorm is forecast for Saturday evening into Sunday. Connecticut could see up to four inches of additional rainfall by the end of the weekend, meteorologists said. Flooding remains a big concern.

WFSB 3 TV chief meteorologist Mark Dixon with Scot Haney said the rain will develop across Connecticut on Wednesday afternoon.

"The steadier, heavier rain ramps up this evening and lasts into the predawn hours of tomorrow. The level 2 risk area for excessive rain has been expanded farther west across CT," according to Dixon and Haney.

"As of this morning, a Flood Watch has been posted for all but Litchfield County. It’s in effect from this afternoon into early tomorrow as 1-2″ of rain could fall, with locally higher amounts. Our First Alert continues as there could be poor drainage and basement flooding… also, smaller streams and creeks could rapidly rise," Dixon and Haney said.

"By tomorrow morning, the steadier/heavier rain should be over. However, the rest of the day looks showery with lingering areas of light rain. The wind will be noticeably stronger as the area of low pressure moves away from CT," Dixon and Haney said. (Read/watch more at WFSB 3 TV).

More rain this weekend

"Yet ANOTHER area of low pressure will impact CT with more rain over the weekend. We’re still a few days out, but timing for the rain has improved as it starts later in the day, which bodes well for the Hartford St. Patrick’s Day parade that steps off at 11am. While chances increase at night, and lasting into Sunday morning… it now looks to end midday, great news for the New Haven parade that steps off at 1:30pm. Taking into account the 2 upcoming rounds of rain (late today into early tomorrow, then over the weekend), parts of the state could receive 2-4″ of rain, with perhaps locally higher amounts! Because of this, we have a First Alert for renewed flooding concerns Saturday night into Sunday morning," Dixon and Haney said.
