The most violent tornadoes, rated EF4 and EF5 with wind speeds exceeding 166 mph, are rare, comprising less than 1% of all tornadoes. Despite their rarity, these high-intensity storms are ...

More than 10,000 tornadoes have been reported across Texas since 1950, according to data from the National Oceanic and ...

An EF3 is a severe tornado with buildings lost, estimated wind speeds of 136 to 165. Then, an EF4 has wind speeds of 166 to 200 mph. Finally, the EF5, which is the strongest with catastrophic ...

EF5 can cause wind speeds of over 200 miles per hour, leaving homes completely swept away and can rip concrete foundation off the ground. There hasn't been an EF5 tornado since May 20, 2013.

With wind speeds surpassing the EF5 rating, some people have begun questioning whether a revised scale, or introducing an EF6 rating, might be considered in the future.

Tornadoes are measured on the EF Scale, which replaced the Fujita Scale in 2007. The scale measures wind speeds of tornadoes by looking at the damage caused on the ground after it has dissipated.

Tornadoes in Maine are generally weak by national standards. They are rated using the Enhanced Fujita (EF) Scale, which classifies tornadoes from EF0 to EF5 based on estimated wind speeds and damage.
