Current watches and warnings Take a few minutes to develop a tornado emergency plan. Identify a safe place in your home for household members and pets to gather during a tornado. Sketch a floor plan of your home or walk through each room and discuss where and how to seek shelter. Identify a second way to exit from each room or area. The winds inside a tornado spiral inward and upward, often exceeding speeds of 300 mph. For a thunderstorm to produce a tornado requires warm humid air near the surface with cold dry air above. These conditions make the atmosphere very unstable, in the sense that once air near the ground is forced upward, it moves upward quickly and forms a storm.A Tornado Watch means that tornadoes are possible. It is important to remain alert for changing weather conditions and approaching storms. Be ready to take shelter immediately. A Tornado Warning is an urgent announcement that a tornado has been sighted or indicated by weather radar. You should take shelter immediately. How Tornadoes Form. A tornado can form in a thunderstorm where the rotating air of an updraft (shown in purple) meets the rotating air of a downdraft (shown in aqua), which has turned upward. Tornadoes only form when a thunderstorm has a particular combination of winds. Air rising in a thunderstorm can begin to spin when it is affected by winds ...A tornado is a rotating funnel-shaped cloud that drops out of a storm cloud to the ground. Whirling winds range from 75 to 300 miles an hour. Tornadoes can measure one mile in width and travel for 50 miles, often changing direction erratically. Mobile homes are particularly vulnerable, but even sturdy, brick buildings on concrete slabs are at risk. "Vertical wind shear creates a rolling tube of air parallel to the ground," she adds. "Heating near the ground then helps lift the horizontal tube of rotating air into a vertical position, forming a funnel cloud. "If the funnel cloud touches down over land it becomes classed as a tornado, or a water spout over water." What made this one so bad?How Tornadoes Form.

This is likely where the phrase “the calm before the storm” comes from. Signs of a passing storm typically include rainfall prior to the actual landing of a tornado, as most tornadoes form from a supercell thunderstorm. However, in the case of a severe storm, calm air ... The swirling, funnel-shaped winds of a tornado are easily recognizable—and they can be very dangerous. But what causes these unique and violent weather pheno... "Vertical wind shear creates a rolling tube of air parallel to the ground," she adds.

"If the funnel cloud touches down over land it becomes classed as a tornado, or a water spout over water." What made this one so bad?A tornado is not necessarily visible; however, the intense low pressure caused by the high wind speeds (as described by Bernoulli's principle) and rapid rotation (due to cyclostrophic balance) usually cause water vapor in the air to condense into cloud droplets due to adiabatic cooling. This results in the formation of a visible funnel cloud or ... In general, tornadoes fall into three types: weak tornadoes, strong tornadoes, and violent tornadoes. A tornado's type is based on its size, how long it lasts and how much damage it causes. Weak tornadoes usually last less than 10 minutes, have winds less than 100 mph (160 kph) and cause damage such as broken tree branches and damaged roofs ... Tornadoes form when warm, humid air collides with cold, dry air. The denser cold air is pushed over the warm air, usually producing thunderstorms. The warm air rises through the colder air, causing... xa
