Estimated 100-year-flood swamps Bucks, Burlington counties: So what does it mean?

Parts of Pennsylvania and New Jersey on Tuesday were facing another round of rain one day after they were swamped by a series of storms that the National Weather Service said caused a rare flash flood emergency.

According to forecasters, Monday's storms dumped 6 to 10 inches of rain in just 3 to 4 hours, swelling the Delaware River in Bucks County, Pennsylvania, and Burlington County, New Jersey.

"Widespread and life-threatening flash flooding is occurring. This is an extremely dangerous situation," the weather service said. "Do not venture out unless it is an emergency or to move to higher ground."

The weather service estimated it to be a 100-year flood, meaning each year there is about a 1% chance of seeing this much rain.

Below is a look at some of the areas that saw the most rainfall on Monday:

  • Croydon, PA - 10.68 inches
  • Croydon, PA - 9.77 inches
  • Bristol, PA - 8.67 inches
  • Florence, NJ - 7.33 inches
  • Delanco, NJ - 5.50 inches
  • NE Philadelphia Airport - 3.99 inches

The rush of water trapped people in their cars and homes.

"Widespread and life-threatening flash flooding is occurring. This is an extremely dangerous situation," the weather service said. "Do not venture out unless it is an emergency or to move to higher ground."
