Minnesota is no stranger to intense weather, with lightning and hail being major concerns. Every year, the state braces for an average of 46 tornadoes, but 2022 saw a dramatic increase with 83 tornadoes touching down. This spike was the highest since the record-breaking 113 tornadoes in 2010. The state's weather patterns are unpredictable, and residents must stay alert.

Thunderstorms in Minnesota can be brief but powerful. A typical thunderstorm covers about 15 miles and lasts around 30 minutes, but even these short-lived events can be hazardous. Severe thunderstorms bring large hail and winds exceeding 58 mph, sometimes reaching speeds over 100 mph. These winds can cause damage similar to tornadoes, leading many communities to sound outdoor sirens as a warning.

When a severe thunderstorm approaches, it's crucial to seek shelter in a sturdy building. Those living in mobile homes should head to a more secure structure. Treat severe thunderstorms with the same caution as tornadoes. Move to a safe shelter if you're in the storm's path. The strong winds from these storms, known as downbursts, can be just as dangerous as tornadoes. They occur when rain-cooled air rushes downward, creating powerful gusts that can topple trees and damage homes.

Downbursts can be mistaken for tornadoes due to their similar roaring sound and destructive power. They can easily overturn mobile homes, tear off roofs, and uproot trees. Campers are particularly vulnerable because falling trees can crush tents and campsites. Straight-line winds, another term for these powerful gusts, cause more damage than tornadoes in the lower 48 states. These winds, exceeding 50 mph, are a significant threat and should not be underestimated.

Hail is another hazard produced by thunderstorms, causing nearly 1 billion dollars in damage annually. Most hailstones are small, about the size of peas, but some can grow as large as grapefruits. Large hailstones fall at speeds over 100 mph and have been known to cause fatalities. Every thunderstorm produces lightning, which is responsible for an average of 43 deaths and hundreds of severe injuries in the U. S. each year.

Lightning safety is paramount. When thunderstorms are nearby, no place outside is safe. If you hear thunder, lightning is close enough to strike. Immediately seek shelter in a substantial building or an enclosed, metal-topped vehicle with windows up. Stay indoors for at least 30 minutes after the last thunderclap. Inside, avoid electrical equipment, plumbing, windows, and doors. Stay off porches and concrete floors, and do not lean against concrete walls. If you're outdoors with no shelter, avoid elevated areas, isolated trees, and bodies of water. Stay away from objects that conduct electricity, like power lines and fences.
