Meteorological synopsis After a morning of intense heat, at noon, huge cumulonimbus clouds were seen forming and traveling in the direction of San Justo. Due to the high relative humidity content and extreme instability, around 13:00 local time, the clouds produced some isolated rainfalls. Tornado summary Then, at about 14:15 local time, a tornado touched down in an open field. Slowly tracking to the south-southwest, the tornado killed several heads of a livestock, tossing cows over 30 m ft on into the air and downed power poles. Several outbuildings were destroyed and lagoon was sucked dry before the tornado crossed the General Belgrano Railroad tracks and entered into town. According to eyewitnesses, the ground was shaking, "as if several jet planes were landing over the houses". The tornado quickly became extremely violent, reaching F5 intensity a few minutes later. The tornado reached a maximum width of 300 m ft on and tore through western part of the San Justo, wrecking multiple factories and over 500 homes, leveling or sweeping clean some homes entirely. "Like ping pong balls", vehicles were thrown hundreds of yards and mangled beyond recognition, and grass was reportedly ripped from the ground. A newspaper image showed a vehicle motor that was embedded into a poured concrete wall by the tornado. A 10 t lb on tractor was found in a wooded area 500 m ft on away from the dealership where it originated. Large trees were torn out of the ground and flew "like matchsticks". A trailer was buried in a 2 m ft mid -wide ditch. As the tornado passed through the town, it turned more to the southwest. Crossing the National Route 11, the tornado struck a family car, lofting it 30 ft m on into the air. Three children, man and woman were ejected from the car. The woman sustained only minor injuries, but man and children were killed and thrown 600 m yd into eucalyptus forest, where hundreds of trees were snapped or debarked; their bodies were later found hanged on trees, being "unrecognizable and stripped of clothes".2013-11-05 Foros Tutiempo - Ver Tema - Tornado de san justo http://www.tutiempo.net/Foro/viewtopic.php?f=1&t=3503 2025-02-18 https://web.archive.org/web/20131105045328/http://www.tutiempo.net/Foro/viewtopic.php?f=1&t=3503 5 November 2013 The tornado abruptly weakened and dissipated seven minutes after reaching F5 intensity. The tornado traveled for at least 1.5 km mi 1, killed 63 people along its path, and caused millions of pesos in damage. The tornado is said by most locals to have changed color multiple times while crossing through San Justo, something that is very unusual for tornadoes to do. The tornado began with a unique violet color, then turned red as it devastated brick homes, with the color being caused by the brick dust it picked up. The tornado destroyed many wooden planks, and turned them into projectiles, which were what caused most of the fatalities.Multiple sources: Grazulis 2001a 260 Grazulis 2001b 3 Grazulis Thomas P.

The local San Justo Hospital was turned into a morgue, with bodies waiting to be identified. Most of the victims were reportedly rendered unrecognizable or caked in mud. Radio communications were cut, and San Justo was left without electricity for some time. The tornado left over 2000 people homeless due to the extreme house damage.
