The rating scale

Tracks are drawn in the color of the rating. The Enhanced Fujita scale rates the damage rather than measuring the wind: the speeds are what that damage is taken to imply.

  1. EF065 to 85 mph

    Light damage. Surface peeled off some roofs, gutters and siding damaged, branches broken, shallow-rooted trees pushed over.

  2. EF186 to 110 mphthis tornado

    Moderate damage. Roofs badly stripped, mobile homes overturned or badly damaged, exterior doors lost, windows broken.

  3. EF2111 to 135 mph

    Considerable damage. Roofs torn off well-built houses, frame homes shifted on their foundations, mobile homes destroyed, large trees snapped or uprooted, cars lifted off the ground.

  4. EF3136 to 165 mph

    Severe damage. Whole stories of well-built houses destroyed, large buildings badly damaged, trains overturned, trees debarked, heavy cars lifted and thrown.

  5. EF4166 to 200 mph

    Devastating damage. Well-built houses leveled, structures with weak foundations moved some distance, cars thrown and large missiles generated.

  6. EF5over 200 mph

    Incredible damage. Strong frame houses swept off their foundations, car-sized missiles thrown more than 100 meters, steel-reinforced concrete badly damaged, high-rise buildings deformed.

  7. Unrated

    The survey recorded a tornado but could not put a number on it, most often because it crossed open country and damaged nothing a rating can be read from.

What the Weather Service recorded

A trough over the eastern Pacific dropped southward over the region bringing a series of shortwaves across interior Northern California. These shortwaves brought enough instability and moisture to produce tornadic supercells to interior NorCal. One tornado was reported on March 25th and five tornadoes were reported on March 26th. The trough also brought heavy snow to the Northern Sierra Nevada and Western Plumas County, mainly Wednesday and Wednesday night (March 26) with snow levels dropping to 4000-5000 ft.

Based on eye witness interviews we believe this was the first tornado to touch down around 5:30 pm, and then tracked southeast for about 5-10 minutes. A pheasant pen and an outbuilding both lost their roofs. The outbuildings roof was made of sheet metal and some individual pieces were thrown between 800-1000 feet east/southeast of the outbuildings location. Some of the heavier pieces (150 lbs) were thrown 350 feet from the original outbuilding.

Based on eye witness interviews, believe this tornado originated around 5:30pm as well and tracked nearly due east along CR41. It removed the roof of a barn near Road R, damaged an outbuilding made of sheet metal, turned over a carport and broke a utility pole (8 inches in diameter) of a local residence just west of Road S. An outcrop of cottonwood trees on a dairy farm at CR 41 and TT was badly damaged. Some of the tree limbs landed on structures to house calves, but no livestock were injured. Also, down road TT, a stop sign was ripped off its metal pole and thrown 50 yards in the field just east.

Based on eye witness interviews, this tornado originated around 5:45 pm at a residence along CR 39, west of Road P. Based on damage, the tornado appeared to track along the fence of the residence, taking out deciduous trees before turning west and taking out the chain link fence. It threw lawn furniture into the residences pool, and lifted an awning up. Two support beams under the awning were pushed over before the awning was returned to it���s original location resting on the remaining support beams. The tornado then tracked through some orange trees, relieving them of a majority of their fruit, then another row of deciduous trees, pushing them to the west. The tornado then tracked through their almond tree orchard uprooting or breaking 60+ of their trees and removing almonds from other trees. The tornado tracked west to the next resident���s orchard taking out another dozen or so of his trees, but a majority of the crop was stripped off the trees. It then hit a tractor parked near his orchard, removing the shade shield and throwing it 157 feet. (Weight is 90 lbs). It also damaged a large eucalyptus tree with a large portion of the tree falling in between the residence and an outbuilding, with a portion landing on a dog kennel just below the tree. 2 trucks on the premises had a back and passenger rear window blown out by flying debris or hail. One of the tucks also sustained damage to a metal tool box in back of the truck. A debris path was apparent across CR 39 as it moved south of the road and impacted another almond orchard. Not much damage to north end of orchard, so tornado may have lifted up for a bit. Tornado touched back down just behind the residence and uprooted/broke 30+ trees. A cotton wood tree on the east end of the residence, top 1/3 of the tree was broken off, and landed immediately to the west into an alfalfa field. Toward the end of the row of almond trees near the residence, one of the uprooted trees was thrown 227 yards WSW into the alfalfa field. There was also a 24 foot debris path across the gravel road where the tree was dragged/carried into the field.

What this means

Ratings are the survey's, read off the damage rather than measured; the rating scale is above. Tornado counts rise through the record as reporting improved, so a year in the 1950s is not comparable with one today except for the strongest tornadoes, which were always noticed.
