This can be your basement or the lowest room in the center of your house or apartment building, away from outer walls and windows. Listen to weather reports for tornado warnings.For instance, in the 1980s, people only had about a five-minute warning before a tornado hit by the late 2000s, the warning time grew to 13 minutes. Thanks to these tools, meteorologists are now able to quickly predict when and where a tornado will form, giving people in a twister’s path more time to seek shelter. This helps scientists pinpoint where and when a twister might form, as well as how strong or long-lasting it might be. Then they analyze that data with supercomputers. Tracking tornadoesĭuring thunderstorms, meteorologists use weather satellites, weather balloons, and buoys to gather data like wind speed and temperature. In North and South Dakota, Nebraska, Iowa, and Minnesota, tornadoes are more likely to form in June or July. Though the storms can happen at any time of the year, tornado season in Texas, Oklahoma, and Kansas occurs in May through early June. When the warm and cool airstreams meet, tornadoes are likely to form. These states are in the path of warm, moist air traveling from the Gulf of Mexico as well as cool air blowing from the Rocky Mountains. This zone in the Midwest extends from Texas to Ohio and includes Iowa, Kansas, South Dakota, Oklahoma, and Nebraska. ![]() state, many form in a region called Tornado Alley.

That being said, a storm that contains lots and lots of lighting could become severe, so strike count is something that meteorologists watch closely as storms evolve. Lightning frequency is not a criteria for a severe storm. LIGHTNINGĪ noisy storm does not mean the storm is severe. ![]() However, because flooding is life-threatening, the National Weather Service will issue flood watches and warnings. Technically, a heavy downpour or storm that produces flooding is NOT considered severe. TORNADOESĪny storm that contains a tornado - even if it isn’t producing a lot of hail, rain, or lightning - is immediately considered a severe storm. ![]() Often, straight-line winds can reach above 80 mph and be just as damaging or even more destructive than tornadic winds. If National Weather Service meteorologists see that a storm is capable of producing a 58 mph gust or greater, they will issue a severe thunderstorm warning. It’s been determined that wind gusts greater than 58 mph are considered severe and can do damage. In May 2021, a 6.4″ diameter hailstone fell in Hondo - that the size of a honeydew melon! WIND Although, as you know, hail can be much larger than that. While even small, pea-sized hail can make a storm noisy, in order to be considered severe and cause significant damage to life and property, hail needs to be 1 inch in diameter, which is the size of a quarter. Now that you know where you stand, here’s what makes a severe storm, severe: HAIL ![]()
