Tornadoes don’t really have a particular season and can form any time of the year. They do occur more frequently in Spring and Fall.

Seasonal Storms

There is a misconception that opening house windows causes the high pressure of the house and low pressure of the tornado to cancel each other out, and that the house can explode if windows are left closed.
In reality, opening the windows does no good and only lets the wind and debris enter your house.

Opening The Windows

According to experts, seeking shelter in a highway overpass or a bridge can be dangerous, as it can cause a ‘wind tunnel’ and sweep you from right under the bridge, or worse, can collapse the bridge if it is weak.
The safer option is to lie low (and flat) in a ditch or low spot.

Protection of A Bridge

Tornadoes can occur anywhere but it seems they are witnessed more in small cities or rural areas. It is not to say that they cannot occur in big cities.

Big And Small Cities

Tornadoes are less common in hilly and mountainous areas, due to the cool, stable air of the regions of higher elevations. The mountains have their own ‘windward sides’ which make the tornadoes break up or weaken.

Mountains and Tornadoes

Tornadoes are generally observed in flat fields, leading to the belief that they only occur in open terrains. Though mountain friction and winds do stop them a little, they can easily be formed over water, so are not entirely land-based.

Flat Lands

Tornadoes don’t have a particular direction of arrival, like the Southwest. They can come from any side of the house and even if they come from a particular direction, the wind can blow in other directions and carry debris anywhere.

Numerous misconceptions are floating around about <a href="https://www.thoughtco.com/how-tornadoes-form-3444287">tornadoes</a>, their behavior, and how to be more safe from them. The ideas might sound like great ideas, but be cautious because acting according to some of these myths might increase the danger to you and your family. 
Here's a look at 7 of the most popular tornado myths you should stop believing. 
While it's true that tornadoes are less common over mountainous regions, they still occur there. Some notable mountain tornadoes include the 1987 Teton-Yellowstone F4 tornado that traveled above 10,000 ft (Rocky Mountains) and the EF3 that struck Glade Spring, VA in 2011 (Appalachian Mountains). 
The reason why mountain tornadoes aren't as frequent has to do with the fact that cooler, more stable air (which isn't favorable for severe weather development) is generally found at higher elevations. Also, storm systems moving from west to east often weaken or break up when they encounter the friction and rough terrain of a mountain's <a href="https://www.thoughtco.com/leeward-and-windward-sides-of-mountain-3444015">windward</a> side.
