Guamúchil Sinaloa was not just any tornado: F0-F1 Fujita-Pearson scale, its level of destruction!
And although the incidence of this type of phenomenon in Sinaloa is lower than in other states, it is not ruled out that this season another one of this level will be registered; predicting where is practically impossible in Sinaloa, highlights the SMN.
For those who were wondering what level of destruction a tornado like the one recorded on the afternoon of Thursday, September 23 in Sinaloa can have, there is an answer beyond the obvious.
According to the Fujita-Pearson scale, the one mentioned by the doctor in geophysics applied to Juan Espinosa Lun a, the level of the tornado on Thursday afternoon in Guamúchil was established between the F0 and F1 range.
What is the level of destruction of this type of system?
-The intensity F0 is related to wind speeds between 60 and 117 kilometers per hour. Its level of destruction is classified as slight, causing minor damage such as branches torn from trees; damage to shallow-rooted trees; damaged signs.
-The intensity F1 with wind speeds between 117 and 181 kilometers per hour, is already related to moderate damage with the ability to lift tiles, sheets, move cars and even sink smaller boats.
The wind level of the tornado recorded in Guamúchil was greater than 100 kilometers per hour and its degree of destruction was observed in the various videos: trees practically uprooted, housing sheets, metal fields moved as if they were sheets of paper. .
It also moved power lines, and literally made people have to grab where they could so as not to be moved by these intense gusts of wind that came suddenly, and after about 15 minutes it ended up disintegrating.
According to the National Meteorological Service, being able to predict a tornado requires more specialized instruments that Sinaloa does not have, so being able to observe important variations is practically impossible.
However, he explained that according to historical records, at least two events of this type are registered annually in the entity, this one would be the first and there would still be another one to be presented.
Fujita-Pearson
Scale The Fujita-Pearson Scale, also called the Fujita Scale, is a scale for measuring and classifying the intensity of a tornado. It is based on the destruction caused to man-made structures and vegetation. It is the most universally accepted. It was developed in 1971 by Tetsuya Fujita and Allen Pearson of the University of Chicago. Although the scale theoretically covers 13 degrees, all registered tornadoes are comprised of six that are shown in the following image:
