Original post: FAIRFIELD/NEW HAVEN COUNTY, CT — A flood watch has been issued through late tonight as heavy rain is forecast all day Friday.

"Excessive runoff will likely result in scattered to numerous instances of flash flooding in urban and poor drainage areas," the National Weather Service said. "Locally considerable flash flooding is possible where axis of heaviest rain develops and sits for several hours. If this heavier rainfall axis develops over the flashy river and stream basins of northeastern NJ, Lower Hudson Valley, and southwestern CT, moderate flood stages could be exceeded."

The weather service added: "A widespread 3 to 5 inches of rain is expected, with localized amounts of 5 to 7 inches possible. Rainfall rates of 1 to 2"/hr likely in heaviest rainfall axis, with rates in excess of 2"/hr possible. Flooding will be exacerbated in coastal areas where heavy rainfall coincides with this morning and evening high tides. The exact axis of excessive rainfall is still uncertain, but those in the watch areas should prepare for the potential of considerable flooding."

Up to five inches of rain is expected in Fairfield/New Haven counties and up to seven inches of rain is possible, the weather service said.

And a coastal flood advisory is in effect until 2 p.m. Saturday for coastal sections of Fairfield County.

"Minor flooding is expected in the more vulnerable locations near the waterfront and shoreline around the times of high tide through Saturday morning, especially with the morning high tide cycles," according to the weather service. "Heavy rain will likely exacerbate the tidal flood threat Friday morning. Some roads and low lying properties including parking lots, parks, lawns, and homes and businesses with basements near the waterfront will experience minor flooding....Minor flooding may also be possible around the times of high tide Saturday night into Sunday morning."
