![]() ![]() We notice that well-constructed homes can find their roofs completely torn off while the foundations of some houses may shift. This is the first classification known as a “strong tornado”. EF-2 Tornado: Estimated sustained winds of 111-135 mph, these types of tornadoes can create considerable damage.Windows can also be broken in these types of tornadoes. Roofs can be stripped off with some mobile homes overturned or badly damaged. EF-1 Tornado: Estimated sustained winds of 86-110 mph, these types of tornadoes can produce some moderate damage.Shallow trees can be knocked over and tree branches can be broken. They can peel off the surface of some roofs and cause some minor damage to the gutter or siding. EF-0 Tornado: Estimated sustained winds of 65-85 mph, these types of tornadoes tend to produce light damage.This scale rates a tornado by the damage they produce and ranges from EF-0 to EF-5, with the strongest being an EF-5. Tornadoes are rated by the Enhanced-Fujita Scale. Severe thunderstorms during a high risk can produce violent tornadoes, including tornado outbreaks, or long-distance wind events like Derechos. High risk (Level 5): A high risk is issued on the most extreme weather days.Severe thunderstorms during a moderate risk can produce strong tornadoes, widespread wind damage, and destructive hail greater than two inches in diameter. Moderate risk (Level 4): A moderate risk is issued when widespread severe storms are possible on a given day.Severe thunderstorms during an enhanced risk will be capable of producing a few tornadoes, several reports of wind damage, and damaging hail between 1-2 inches in diameter. Enhanced risk (Level 3): An enhanced risk is issued when numerous severe storms are possible on a given day.Severe thunderstorms during a slight risk day will be capable of producing a tornado or two, strong to damaging wind and gusts, or hail up to an inch in diameter. These are also frequent in South Florida. Slight Risk (Level 2): A slight risk is issued when a few scattered severe storms are possible on a given day.The severe thunderstorms will have a very low tornado risk, sustained winds of 40-60 mph, or hail up to an inch in diameter. This is a frequent outlook and indicates a low risk for severe weather. Marginal risk (Level 1): A marginal risk is issued when an isolated severe thunderstorm or two is possible on a given day.There are five risk levels that an outlook will range from: Weather outlooks are issued by the Storm Prediction Center, a special branch of the National Weather Service, and are focused on forecasting severe weather across the United States and how significant a severe weather day may be. ![]()
