How to Stay Safe
Stay informed by following local forecasts. Secure loose outdoor items to prevent damage. If hail or strong winds approach, move indoors and stay away from windows.
Additionally, have an emergency kit ready with essentials like flashlights, batteries, bottled water, and non-perishable food. Ensure your mobile devices are fully charged in case of power outages. If you are driving during the storm, pull over to a safe location away from trees and power lines. Avoid flooded roads, as water levels can rise quickly and create dangerous conditions. | Oregon Storm Warning
Consider having a weather radio or mobile app with storm alerts enabled. These tools will provide real-time updates about storm movements and warnings. If you live in a mobile home or a less sturdy structure, seek shelter in a stronger building before the storm arrives. If a tornado warning is issued, take cover in a small interior room on the lowest floor and avoid windows.
After the storm passes, check for damage around your property but stay away from downed power lines and report them to local authorities. Help neighbors who may need assistance, especially for those with disabilities. Stay cautious of lingering hazards such as broken tree limbs or unstable structures. | Severe Thunderstorms Oregon Washington
