EF1 and EF2 are ratings on the Enhanced Fujita scale, which uses the damage a tornado does to assign it to one of six strength categories which run from EF0 at the weakest to EF5 at the strongest.
An EF1 tornado has estimated winds of 86-110 mph. It is considered a relatively weak tornado with typical damage including broken windows, badly damaged roofs, and overturned trailers.
An EF2 tornado with winds of 111-135 mph is considered the beginning of a strong tornado. Typical Ef2 damage includes roofs torn from well-built houses, and trailer homes completely destroyed.
Yes they have. One time during Tropical Storm Fay a EF2 and EF1 tornado in wellington FL
An EF2 tornado is actually considered moderately strong, not weak. It is the third level on the Enhanced Fujita (EF) scale, with estimated wind speeds between 111-135 mph. The scale ranges from EF0 (weakest) to EF5 (strongest), so an EF2 tornado is not the third weakest.
As of December 11, 2013 the last known tornadoes were in Florida and North Carolina on November 26. The Florida tornado was an EF1 while the one in NC was an EF2.
If by type you mean rating, then the numbers are as follows: EF0: 759 EF1: 617 EF2: 195 EF3: 61 EF4: 17 EF5: 6
Usually it would take at least an F2/EF2 tornado to remove the roof from a house, but if it is not well secured and F1/EF1 could remove it.
The 3 general categories of tornadoes are weak tornadoes (EF0 and EF1), strong tornadoes (EF2 and EF3), and violent tornadoes (EF4 and EF5). These categories are based on the Enhanced Fujita (EF) scale, which rates tornado intensity based on the damage they cause.
The island of Malta has been hit by several tornadoes, some of these were very destructive. Most of the tornadoes that hit Malta are waterspouts that make landfall. ON September 23, 1551 or 1556 a very powerful waterspout hit La Valletta. It killed 600 people and was likely an F4. Recently weak tornadoes hit Malta (EF0-EF1), the strongest was an EF1/EF2.
It depends on which one you are referring to as there were 10 tornadoes in Montana in 2010. The two most notable are: The Billings EF2 of June 20, which lasted 12 minutes and The Sheridan County EF3 of July 26 which lasted 37 minutes (this was Montana's only killer tornado for the year). The 8 others lasted as follows: The McCone County EF0 of May 27 which lasted 15 seconds The Carbon County EF2 of June 16 which lasted 5 minutes The McCone County EF1 of June 16 which lasted 8 minutes The Valley County EF0 of June 21 which lasted less than a minute The Otter area EF1 of June 21 which lasted 10 minutes The Powder River County EF2 of June 21 which lasted 10 minutes The Park County EF2 of July 2 which lasted 7 minutes The Wheat land County EF0 of September 9 which lasted 5 minutes
Tornado categories are based on the Enhanced Fujita (EF) scale. Wind speeds associated with each category are as follows: EF0 (65-85 mph), EF1 (86-110 mph), EF2 (111-135 mph), EF3 (136-165 mph), EF4 (166-200 mph), EF5 (over 200 mph).
There were five tornadoes in Missouri on May 13, 2009. The first, rated EF1 ocurred near Milan, but did not actually hit the town. A second EF1 tornado hit the town of Novringer. The third and most significant tornado of the event was an EF2 that hit Kirksville, killing 2 people. Two other tornadoes, both rated EF0, passed near Edina.
If by last night you mean April 4, 2011 then yes. There were at least 5 tornadoes confirmed in 3 states. In Kentucky there were 2 EF1 tornadoes and an EF2. In Tennessee there was also an EF1 tornado. In Ohio there was an EF0 tornado.
Tornadoes. There is also a classification system (the Enhanced Fujita system, EF0 through EF5) - it is mainly based on the destruction that a tornado causes, which gives some clue as to the wind speeds. EF0-EF1 = weak EF2-EF3 = strong EF4-EF5 = violent
