Severe Thunderstorm Prep: 10-Minute Checklist

When a Severe Thunderstorm Warning is issued, you may have minutes to act. Damaging winds (58+ mph), hail, lightning, and tornado spin-ups are all possible.

Immediate Actions (10 Minutes)

• Move indoors — stay away from windows
• Charge phone and power bank
• Unplug sensitive electronics (surge protection)
• Bring pets inside
• Secure trash bins and lightweight outdoor items
• Test NOAA weather radio is on alert mode

Shelter Location

• Lowest floor, interior room with no windows
• Bathroom or closet under stairs works well
• If in a mobile home, evacuate to a sturdy building before the storm arrives

During the Storm

• When thunder roars, go indoors — lightning can strike 10 miles from rainfall
• Avoid plumbing and corded phones
• If driving, pull over away from trees and power lines
• If a Tornado Warning is issued, move to interior lowest floor immediately
