The Two-Location Fallback
Before storm season starts, identify exactly two places you can move your car on short notice.
Option A: The covered parking you can reach in 15 minutes. This is a mall parking garage, a friend's carport, a grocery store with a concrete overhang, or a bank drive-through with a roof. It doesn't need to be free. It needs to be available between 2 PM and 7 PM on weekdays and close enough that you can Uber back to work or home. Drive there once during non-storm conditions. Note the exact entrance, the ceiling height clearance, and whether you need to pay.
Option B: The underpass or bridge you can reach in 8 minutes. This is your emergency fallback if you have 20 minutes of warning instead of two hours. According to National Weather Service safety guidance, overpasses are not recommended for tornado shelter, but for hail protection they function adequately as last-resort vehicle cover. Find one with a shoulder wide enough to fully clear traffic lanes. Screenshot the exact GPS coordinates.
The entire system is: if Moderate or High risk is forecasted for your county and you're not home, the car goes to Option A during your lunch break. If a severe thunderstorm warning is issued with hail mentioned and you have less than 30 minutes, the car goes to Option B immediately.
