Severe Thunderstorm Watch: What It Means After NJ Storms

The short answer

A severe thunderstorm watch means conditions are favorable for severe thunderstorms to develop. In this case, the watch preceded Monday night's storms that brought heavy rain, flash flooding, hail, and lightning to parts of New Jersey, prompting water rescues and power outages. The watch is issued by the National Weather Service and covers a broad area, alerting residents to be prepared for potentially dangerous weather. While the watch has expired for most areas, cleanup and recovery continue, and isolated storms remain possible Tuesday.

Why it's trending

The phrase 'severe thunderstorm watch' is trending because Monday night's powerful storms caused significant damage across New Jersey, including flash flooding, hail, and lightning-sparked fires, leading to widespread power outages and water rescues. As residents clean up and more storms are possible Tuesday, searches for the watch definition and current alerts have spiked.

A severe thunderstorm watch was in effect Monday night as a line of powerful storms moved through New Jersey, bringing heavy rain, flash flooding, hail, and lightning. The storms overwhelmed roadways in several towns, trapping drivers and prompting dozens of water rescues. In Hawthorne, Route 208 was submerged, and the fire department responded to 17 water rescues. In River Edge, five people were rescued from vehicles caught in floodwaters, according to ABC7 New York.

The storms also caused property damage: lightning struck a building in Ridgewood, traveling to the basement and blowing out the electric meter, sparking a two-alarm fire. Hail was reported in Franklin Lakes and Edison. Power outages affected thousands, as tracked by NJ.com's outage map. New Jersey Transit service on the Pascack Valley Line was temporarily suspended after a tree fell across tracks near Westwood Station.

While the most intense storms have moved out, forecasters say additional showers and thunderstorms remain possible Tuesday, meaning isolated flooding and scattered power outages could still develop. Residents are urged to avoid driving through flooded roadways. The severe thunderstorm watch served as an early warning for these events, and its relevance now lies in the ongoing cleanup and the potential for more severe weather.

A severe thunderstorm watch differs from a warning: a watch means conditions are favorable for severe storms, while a warning means a storm is imminent or occurring. Monday's events underscore the importance of heeding these alerts, especially as extreme weather events become more frequent. Residents should stay informed via weather apps and local news for updates on additional threats.
