Los Angeles: Tornado warning Santa Clara County and tornado warning Santa Cruz. There is a fear of Tornado in Santa Clara and Santa Cruz counties. This has taken many off guard as these places are not known to have faced tornado or hail much.
But the National Weather Service has issued this tornado and hail warning saying that a tornado with a speed of 35 miles per hour was moving towards the Santa Calara and Santa Cruz counties.
The tornado at 35 mile per hour speed is not very dangerous, though it doesn’t mean that people shouldn’t seek shelter in stronger buildings or in basements.
There are several different scales for rating the strength of tornadoes. The Fujita scale rates tornadoes by damage caused, and has been replaced in some countries by the updated Enhanced Fujita Scale.
An F0 or EF0 tornado, the weakest category, damages trees but not substantial structures. An F5 or EF5 tornado, the strongest category, rips buildings off their foundations and can deform large skyscrapers. The similar TORRO scale ranges from a T0 for extremely weak tornadoes to T11 for the most powerful known tornadoes.
Doppler radar data, photogrammetry, and ground swirl patterns (cycloidal marks) may also be analyzed to determine intensity and award a rating.
