How much rain did we get? Long Island floods

Hundreds of people were stranded and many daring vehicle rescues performed as powerful weekend storms dumped nearly a foot of rain on parts of Connecticut and followed it up with a grand finale late Sunday, again lashing the tri-state with blinding downpours and crippling travel.

Rainfall rates of up to 3 inches an hour had been expected overnight. By early Monday afternoon, a flood warning remained in effect for Long Island's Suffolk County, while a river flood warning stood in Fairfield County, Connecticut. Flash flood warnings that lingered overnight expired around sunrise. Check the latest active alerts here.

In the past 24 hours, two locations in the Northeast reached the threshold of a 1,000-year rainfall event, meaning the rainfall had a 0.1% chance of occurring for these locations in any given year. Those locations include Fairfield and New Haven counties in Connecticut, where 10 inches of rain fell in 12 hours around Oxford and Southbury.
