Friday, July 20th, 6:01pm: Flash Flood Watch Issued for Saturday Afternoon/Evening, July 21st

The National Weather Service has issued a Flash Flood Watch for Avalon and other communities along the Jersey Shore.  The Watch is in effect from Saturday afternoon through late Saturday night, July 21st.  The Watch means that a few inches of rainfall are possible which could cause some street flooding in a very short period of time.

A low pressure system will form just off the coastline of New Jersey on Saturday.  This system may bring showers, thunderstorms with heavy rain, and gusty winds through the afternoon and evening hours on Saturday. Rain may fall very heavy in a short period of time which may cause street flooding throughout our community. There are sections of Avalon where this heavy rainfall may produce widespread street flooding, including the north end beach blocks and along sections of Dune Drive.

Never attempt to drive your car on any flooded street as this puts you and your vehicle at risk. Water is always deeper than it appears to be in the street.  If you live on a street that typically floods during rainstorm events, consider moving your vehicle to another portion of Avalon that is not prone to street flooding during heavy rainfall events.  Coastal flooding is not expected; this storm is expected to produce street flooding from heavy rainfall.

Avalon has produced a flood risk map that shows the areas of our community that may be impacted by heavy rainfall events.  Please use this map as a guide for planning purposes.


Follow all instructions provided by the Avalon Beach Patrol over the weekend; always swim in the presence of a lifeguard.  Continue to follow the forecast on traditional media outlets.  Avalon may implement a Reverse 911 phone call Saturday morning if the forecast remains the same, or worsens.
