Overview
- The Storm Prediction Center and local NWS offices put nearly 80 million people on alert Sunday along the East Coast from northern Georgia to Maine for damaging winds, very large hail, frequent lightning and isolated tornadoes.
- A slow‑moving line of storms rolled east overnight into the Northeast with multiple tornado warnings reported and Flood Watches in parts of New England where soils are already saturated.
- Storms that began in the central Plains produced extreme local damage Saturday, including reports of softball‑sized hail and measured wind gusts up to about 84 mph that toppled trees and left outages.
- Forecasters warned that training downpours over wet ground could cause localized flash flooding and that heavy rain disrupted events in North Texas, where broadcasters issued a First Alert Weather Day for isolated flooding risks.
- Internationally, the India Meteorological Department said the southwest monsoon will advance over several states with heavy‑rain alerts including a red warning for Delhi‑NCR, and the UK Met Office forecasts a brief warm spell later this week with a likely thunderstorm risk over eastern England.
