Severe Weather Statistics

Page

Though not a prominent location for severe weather like other parts of the United States, West Virginia still sees its fair share of severe weather. Whether the severe weather comes in the form of tornadoes, wind damage, hail damage, or flooding (the latter of which is so prominent, we’ll talk about that in a completely separate post), the inhabitants of the Mountain State are well aware of nature’s wrath even on our hills and valleys.

Just how often does the Mountain State see severe weather, in particular, our area? The answers are shown below! Data statistics are from the years 2000-2015, with data being provided by the National Weather Service. A report is taken in by weather observers, trained spotters, and National Weather Service employees. Fitzweather’s severe weather analysis for our region is divided in the following way:

CONCLUSION

West Virginia averaged over 250 storm reports from 2000-2015. That’s an average of about 5 reports per week. Kanawha County overwhelmingly averaged more storm reports than any other county in our region. This is very likely due to the much higher population of the county, which allows for more bodies to cover more locations of the county. Counties in our region that saw much lower figures, such as Clay and Gilmer Counties, have very low population densities, which could be the reason for the lower storm report totals.

In general, like anywhere else in the United States, West Virginia receives its fair share of severe weather, with a variety of severe weather occurring during the period studied.
