The National Weather Service has issued a Flood Watch for Southbury beginning at noon on Sunday throughout Monday morning.
Steady rainfall, associated with an incoming storm beginning this afternoon, may bring up to three inches of rain over the next 24 hours.
The rain is expected to begin shortly after 12 p.m., becoming heavy in the later afternoon hours with the strongest rainfall occurring overnight. Rainfall rates approaching an inch per hour in the heaviest rain bands is possible, according to the weather service.
The weather service urges residents to continue to monitor weather reports and warns those living in areas prone to flooding that they should be prepared to take action should flooding develop.
Floods forced residents along the Pomperaug River out of their homes three times in 2011 and affected hundreds more, especially those living on River Road, Flood Bridge Road, Manor Road and surrounding areas.
