Are derechos becoming more common?

Whether such strong derechos might become more, or less, common due to climate change is difficult to say, however. Some anticipated effects of climate change, such as warming at the planet's surface, could increase the likelihood of more and stronger derechos by increasing atmospheric instability.

How rare are derechos?

COMPARISON TO PAST DERECHOS

Does Florida get derechos?

Why do tornadoes not hit big cities?

First, since urban areas only cover 3% of America's land surface, it's more difficult for a tornado to strike a city because 97% of the nation is not urbanized (which is likely why many people believe cities are protected from twisters).
