DENVER (KDVR) — Spring has arrived, but instead of rain and thunderstorms, Colorado is dealing with drought and extreme fire danger.
How often does Denver really have to worry about a tornado threat?
Tornadoes in Colorado
Most tornadoes in Colorado occur over the Eastern Plains and are on the lower end of the Enhanced Fujita Scale of tornado intensity.
Colorado is not located in the normal “Tornado Alley”, but Weld County actually has the number one rank for the weakest (EF0, EF-1) anywhere in the United States.
There are an average of around 31 weak tornadoes (EF0, EF1) each year across Colorado. Most of those happen in the Eastern Plains.
For the most part, tornadoes in Colorado occur in the afternoons with the development of the afternoon thunderstorms.
Do tornadoes ever hit Denver?
Has it happened? Yes. But strong tornadoes in the Denver metro are extremely rare.
On June 15, 1988, Meteorologist Chris Tomer said an F2 and F3 tornado hit the Denver metro.
Tornadoes in Denver are rare because of the city’s proximity to the Foothills and mountains.
“It takes some distance for the thunderstorms to mature and the wind sheer to maximize kind of like a spinning ice skater,” shared Meteorologist Chris Tomer.
Colorado’s tornado season is traditionally May through August, but we have had tornadoes from February to as late as October.
Hail in Colorado
Severe hail is actually a bigger and growing problem across Denver and the Front Range. We are technically in “Hail Alley”, a term used by Meteorologist Chris Tomer.
Not only does hail fall several times a year in Colorado, it’s also incredibly costly for our state.
That storm surpassed the historic storms of July 20, 2009 and July 11, 1990.
A 1.1 billion dollar hail storm hit the state in July of 2009. Thornton was buried under 8 inches of hail during that event.
Here’s a look at some of the hail that has fallen in Colorado over the past few years:
