This year’s tornado season has started off as one of the deadliest in at least a decade. That means early warning systems and taking proper precautions are increasingly important.
A tornado, or twister, forms when warm, moist air from the Gulf of Mexico collides with cool, dry air from Canada. For southern states, that’s most likely to occur in the spring, while summer is the more prevalent time further north. This weather condition spawns about 1,000 tornadoes a year in the United States.
