A microburst is defined by the National Weather Service as a localized, descending column of air within a thunderstorm measuring 2.5 miles or less in diameter.
It occurs when an updraft weakens, allowing the core of air and water to plummet and spread destructive winds upon ground impact.
To break it down even further, FOX Weather Meteorologist Britta Merwin said, "A microburst is when a thunderstorm is kind of falling apart and decaying and the updraft kind of collapses, and that means all the air rushes down from the thunderstorm to the ground, and you have this massive burst of air."
According to the NWS, winds can reach up to 100 mph in microbursts, which is equivalent to an EF-1 tornado.
