This is so unusual because a tornado tears through part of Los Angeles County

Los Angeles County Sheriff’s Office estimates there were 48 tornadoes between 1950 and 2021 resulting in a total of 47 affected buildings and buildings

There were 44 tornadoes in Los Angeles County from 1950 to 2021, which comes out to less than one per year. Most were classified as being weak and did not result in any injuries.

The fire department deemed 11 of the 17 buildings damaged too dangerous to use because of the intense microcell.

Additional video of the Montebello storm shows a swirling cloud of black debris as the roof of a nearby building gets blown off. Vehicles can be seen with damage and shattered windows.

LAist reported that it caused a lot of damage as it was weak, but even with that rating, 17 structures were damaged, a tree was upended and one person suffered minor injuries. Taking shelter indoors and away from windows is the best way to stay safe in a tornado.

There are usually weak funnel clouds there, but they do occur a couple of times a year without causing much damage. There were landspouts that were not rotating on Tuesday in southern California.

They are commonly referred to as landspouts (similar to a waterspout, but over land). These differ from more traditional tornadoes that form from rotating thunderstorms, like those common in the Central Plains and the Southeast. While landspouts can cause damage, it is generally not extensive or severe.

California has been flooded by at least 12 atmospheric rivers in the last months, causing devastating floods and Hurricane-force winds. An atmospheric river is like a fire hose that carries saturated air from the tropics to higher latitudes, dumping relentless rain or snow.

Fierce winds and downed trees in the San Francisco Bay Area led to the deaths of at least five people. The peak of the storm resulted in the fall of over 700 trees and limbs, as well as glass and debris falling from highrise towers, according to the city of San Francisco.

The Northern Sky Service and Enhanced Fujita Scale: The Montebello Tornado as an EF1 or Weak Traceable Tornado

According to the NWS, there are two key components to tornadoes. The first is instability, with warm, moist air near the ground and cooler dry air higher up. The second is a change in wind speed or direction higher up in the atmosphere. Taken together, these conditions create a rotating updraft, which creates a supercell thunderstorm and eventually a tornado.

The Enhanced Fujita scale is used by the NWS to classify tornadoes. The Montebello tornado was classified as EF1, or weak.
