Tornado warnings blanketed multiple states Thursday as severe storms with rotating clouds moved across the country.

Residents in affected areas were told to seek shelter immediately in basements or interior rooms away from windows.
A tornado warning remained in effect for Columbia County, Oregon, near Deer Island on Thursday. National Weather Service Portland said radar showed rotation in the storm as it moved north at about 20 mph. The agency warned of pea-sized hail and urged residents to take cover in sturdy shelter.
The warning highlighted the dangers of rotation that can spawn tornadoes. Residents in the area were advised to move away from windows and avoid mobile structures that offer little protection during severe weather.
In Michigan's Livingston County, a tornado warning issued near Fowlerville was set to expire at 3:45 p.m. Thursday. ClickOnDetroit reported the storm was moving southeast at 40 mph with radar-indicated rotation. Flying debris posed a serious threat, and damage to mobile homes, roofs, trees, windows and vehicles was possible.
The National Weather Service predicted specific arrival times: Howell and Fowlerville around 3:10 p.m., Brighton and Pinckney around 3:25 p.m., and Hamburg and Whitmore Lake around 3:30 p.m. A separate warning covered the Grand Rapids area, where hail reached up to 0.75 inches and flash flooding threatened parts of Gratiot and Saginaw counties.
Beyond tornado threats, flood warnings remained in effect across parts of the Northeast, including northern Delaware and southern New Jersey. Rising rivers posed dangers to drivers and homes in low-lying areas. National Weather Service officials urged motorists to avoid flooded roads, repeating the safety message: turn around, don't drown.
The multiple warnings reflected how a single weather system could spawn different hazards across wide areas. Residents faced a combination of tornado risks, hail, heavy rain, and flooding within hours as storms tracked through different regions at varying speeds.
Tornado warnings are issued when National Weather Service radar detects rotation in a storm, or when a tornado is actually spotted. Sometimes spotters on the ground confirm what radar shows. Unlike watches, which mean conditions are favorable, warnings mean danger is imminent and action is needed right now.
The safest action is to move to a basement or the lowest interior room in a building, away from windows. People in mobile homes should leave immediately and get to a sturdy building or designated shelter. The few minutes it takes to reach safety can mean the difference between life and death when a tornado strikes.
