The Flood Watch will remain in effect as "rain with an approaching frontal system should become heavy by late day Wednesday," according to the National Weather Service.
"Flooding of urban, low-lying and poor drainage areas is possible as early as the Wednesday evening rush hour, with one to 2 inches of rain expected by that time," the National Weather Service said. "As the heavy rain continues Wednesday night, storm total rainfall will increase to 2.5 to 3.5 inches with locally higher amounts, increasing the threat of widespread, significant urban, low-lying and poor drainage flooding, as well as flooding of small streams and rivers."
Rain will become heavier Wednesday, with high temperatures reaching only the low 50s.
The Flood Watch is in effect from 2 p.m. Wednesday until noon on Thursday across all of Connecticut, New York City, Westchester County, N.Y., and northern New Jersey.
Residents are advised to monitor later forecasts and be alert for possible flood warnings.
The latest front is expected to clear from the area overnight on Thursday, but a chance of rain continues through the weekend.
