A mix of heavy rains and thunderstorms could result in flooding in areas near the Connecticut shoreline starting late Friday afternoon and into early Saturday morning.
The National Weather Service has issued a "Flood Watch" that covers southern Fairfield County, and all of New Haven and Middlesex counties.
With the region already soaked from rains earlier this week, some 1 to 2 inches of additional heavy rain is expected to fall — with locally higher amounts possible in some areas during the storm, the weather service reports.
"A slow moving cold front will move across the area later today through tonight. Rain will increase in coverage during the afternoon and become heavy at times at night, with the potential for [...] embedded thunderstorms," according to the Flood Watch statement.
"The heaviest rain is expected to coincide with high tide on the Atlantic and western Long Island Sound tonight, which could exacerbate flooding along the south shore of Long Island and Southern Fairfield County."
There is an increased threat of significant urban flooding, along with flooding of -low-lying and poor drainage areas, the meteorologists warn in their report.
The good news is that once the rains move out early Saturday morning, the rest of the weekend looks to be a pleasant one, with only a slight chance of rain and high temperatures expected to reach the low 70s.
