Weather reports will callout serious weather conditions predicted in the next 48-24 hours. There are Tornado Watches that are issued when conditions are favorable for tornados to form. That will cover a several hour period where you should be aware and alert for threat notices. Then there are Tornado Alerts. These are issues when either someone has reported seeing a funnel cloud or the radar systems show a funnel type formation. These alerts usually cover a county sized area. When you see an alert you should seek shelter. This means ideally underground like a basement or storm shelter. Otherwise the most secure part of a building. Bathrooms are good because they are small with lots of walls but if the building comes down they offer limited protection. A large structure like a warehouse should have a designated storm shelter where extra protection is built into an area. This may be an office or bathroom with concrete or metal cladding that is securely anchored in the ground.
