Severe Thunderstorm Warnings Affect Multiple US, Canadian Regions with High Winds, Hail, Flood Risks

Severe thunderstorm warnings have been issued across multiple regions in the United States and Canada due to storms producing damaging winds, hail, and heavy rain. In southwestern St. Tammany Parish, Louisiana, storms with winds up to 60 mph are causing downbursts and marine warnings for Lake Pontchartrain and Lake Maurepas. Wisconsin’s Wood and Portage counties face severe storms with wind gusts up to 60 mph and hail up to three-quarters of an inch, prompting advisories to seek shelter immediately. In Ontario, Canada, a line of severe thunderstorms is moving east with winds reaching 90 km/h and nickel-sized hail, likely causing utility outages and property damage. Meanwhile, in the north Shuswap region near Celista, Environment Canada warns of heavy rain leading to flash flooding and debris flows, particularly over burn scar areas from recent wildfires. Residents in all affected areas are urged to take immediate safety precautions and stay updated with local weather alerts.
