Tornado watch vs. tornado warning

Tornado Watch: Conditions are favorable for tornadoes. Storms can develop quickly. Treat this like a prep window.

• Stage protection for windows, doors, and garage. Confirm fasteners and panel labels.
• Clear lightweight debris from around the home if it’s safe to do so. Secure trash bins, furniture, and tools.
• Move vehicles into a garage or away from trees and power lines.
• Identify your interior shelter (lowest level, small interior room, away from windows). Place shoes, flashlights, and helmets there now.
• Charge phones and battery packs. Enable Wireless Emergency Alerts and local alerts.

Tornado Warning: A tornado has been indicated by radar or spotted. Act immediately.

• Go to shelter now. Do not finish prep tasks once a warning is issued.
• Protect your head and neck. Use a mattress, cushions, or helmets. Keep pets with you.
• Avoid windows and large open rooms. Put as many walls between you and the outside as possible.

Securing openings and weak points (watch stage)

Windows and glass

• Install rated shutters or labeled panels if you have them. Verify anchors are tight and edges are seated.
• If using temporary solutions, apply interior safety film or exterior wrap per manufacturer guidance on dry, clean surfaces.
• Close curtains or blinds to reduce glass shrapnel spread if breakage occurs.

Exterior doors

• Use all latches and deadbolts. For double doors, lock top and bottom flush bolts fully.
• Add temporary bracing bars or manufacturer door braces where applicable.
• Remove loose mats and décor that could become projectiles.

Garage doors

• Install a rated bracing kit if available. Confirm vertical supports are snug and footings are set.
• Do not rely on vehicles to “block” the door. The goal is uniform reinforcement across door panels.
• Keep the door closed. A failed garage door can rapidly pressurize the home and lift the roof.

Roof and yard

• Secure or store lightweight items. If safe, lay down patio umbrellas and tie down grills.
• Confirm gutters and downspouts are clear to reduce water intrusion if heavy rain accompanies storms.
• Do not climb on the roof. Save any tarp or membrane staging for after the storm and only when conditions are safe.

Safety and shelter during a warning

• Go to a basement, storm shelter, or the lowest interior room. Bathrooms or closets near the center of the home are good options.
• Protect from flying debris. Wear shoes and a helmet if available. Use a mattress or heavy blankets for added protection.
• Avoid windows, exterior walls, and garages. Do not shelter in vehicles or under highway overpasses.
• Keep a flashlight handy. If power fails, avoid using candles.

After the storm: quick checks and documentation

Only exit your shelter when warnings expire and it’s clearly safe to do so. Watch for downed lines, gas odors, and unstable structures.

Exterior walk‑around (from the ground)

• Scan for missing shingles, bent or missing flashing, and visible roof decking. Look for debris punctures in roofs and siding.
• Check windows and doors for cracks, broken seals, or water around frames and sills.
• Inspect the garage door for racking, bent tracks, or panel deformation.
• Note tree damage and anything leaning or at risk of falling.

Interior checks

• Look for new ceiling spots, drips, or damp insulation access points. Listen for dripping in walls.
• Check the attic from the hatch only if it’s safe. Avoid stepping on wet or sagging drywall.
• Photograph everything. Capture wide shots, then close‑ups of damages and serial plates for doors or windows.

Temporary enclosures and covers

If there is an opening, your goal is to keep water out and prevent further damage until permanent repairs are made.

• Windows/doors: Use polycarbonate panels or plywood cut to fit with proper anchors. For smaller breaks, cover with plastic sheeting and tape on dry surfaces, then add a rigid layer if possible.
• Roof penetrations: If decking is exposed, a properly installed temporary wrap or membrane can shed water and resist wind uplift. Avoid makeshift tarps that flap or pool water.
• Garages: If the door is compromised, do not operate it. Brace from the interior and cover openings to block rain and debris.

When in doubt, schedule a professional assessment. Working at heights or around damaged glazing is hazardous.
