The spring season is often the busiest time of the year for tornadoes across the United States. While most tornadoes have winds that are less than 100 mph, there are some larger ones that have winds that can top 300 mph. These are often known as wedge tornadoes and usually occur in the plain states, such as Kansas and Nebraska. A tornado can leave a destruction path greater than a mile wide depending on the size of the funnel and several miles long. Tornadoes in the plain states usually travel for longer distances because there aren’t many houses, buildings, and trees to inhibit the air flow that can break the funnel apart. Hurricanes and tropical storms can spawn tornadoes because of the low pressure, high winds, and the circulation associated with these storms. If there is any kind of possible rotation associated with a thunderstorm system or with a front that is sweeping through an area, then there is a possibility of tornadoes developing. The direction of tornadoes is often southwest to northeast. Few tornadoes travel north to south or northeast to southwest simply because of the way that the jet stream flows across the country and the way that fronts sweep across the country from west to east.
