The concluding message of the passage indicates that people should heed storm watches and warnings. Tornadoes represent a significant threat due to their raw destructive power, as depicted in the provided context about their ability to blow houses away and pierce tree trunks with pieces of straw. Additionally, a car provides safety during electrical storms due to its Faraday cage effect, but there is no mention that this makes a car a safe shelter from tornadoes specifically. The narrative passages provided further illustrate the awe and fear that storms can elicit, reinforcing the respect and caution that should be applied when dealing with severe weather events such as tornadoes.
