Overview
- The Storm Prediction Center and local NWS offices issued multiple severe thunderstorm watches Tuesday as numerous strong to severe storms moved east from the Ohio Valley into the Mid‑Atlantic and Northeast.
- Forecasters say damaging straight‑line winds are the main hazard with many clusters and bowing segments likely to produce gusts commonly between 55 and 75 mph that can topple trees and snap power lines.
- The Weather Prediction Center warned of a growing flash‑flood threat where storms train or back‑build, with radar and guidance showing rainfall rates up to 2–3 inches per hour and localized totals of 2–6+ inches possible in vulnerable corridors.
- A supercell along a warm front produced several brief tornadoes in northern New Jersey and officials continue watch and warning coordination where low‑level rotation is observed.
- Storm experts emphasize sustained mesoscale coordination across SPC, WPC, and local forecast offices and warn residents to expect repeated rounds of storms through the evening with likely travel disruptions, power outages, and rapid urban flooding.
