Of all the maps you might use in a year, here’s one you should definitely peruse: the Federal Emergency Management Agency’s National Risk Index.

The map measures Colorado communities and those across the country most at risk of 18 hazards: avalanche, coastal flooding, cold wave, drought, earthquake, hail, heat wave, hurricane, ice storm, landslide, lightning, riverine flooding, strong wind, tornado, tsunami, volcanic activity, wildfire, and winter weather.

For all of the crazy Colorado weather we’ve seen recently — lightning (our station even got hit recently), hail, rain storms filling rivers, red flag warnings — most of Colorado’s risk remains moderate and low compared with the rest of the nation. Did you see how big that hail was that fell during that huge Northern Colorado storm?

FEMA’s National Risk Index map is a tool governments and industry (think insurance companies, among others) use to identify environmental and social risks, community resilience and expected annual losses.

Colorado’s Front Range is at the highest risk in the state, as seen below, with yellow being at “relatively moderate” risk compared to the rest of the nation. Light blue represents relatively low risk and darker blow very low risk.

Dig the next level deeper, and you will see some areas of the Front Range — and the rest of Colorado — that leap to “relatively high” risk.

Hail, lightning and flooding are very high risk in some areas of Loveland, Fort Collins and Wellington.

Wildfire and landslide risks put areas in the foothills and mountains west of Boulder, Loveland and Fort Collins and along the I-70 corridor at higher risk than the state average and at the 90.4 percentile nationally.

The interactive map allows users to pick specific risks, such as drought, and see the risk by county and Census tract.

LOOK: The most expensive weather and climate disasters in recent decades

Stacker ranked the most expensive climate disasters by the billions since 1980 by the total cost of all damages, adjusted for inflation, based on 2021 data from the National Oceanic and Atmospheric Administration (NOAA). The list starts with Hurricane Sally, which caused $7.3 billion in damages in 2020, and ends with a devastating 2005 hurricane that caused $170 billion in damage and killed at least 1,833 people.

LOOK: The most extreme temperatures in the history of every state

Stacker consulted 2021 data from the NOAA's State Climate Extremes Committee (SCEC) to illustrate the hottest and coldest temperatures ever recorded in each state. Each slide also reveals the all-time highest 24-hour precipitation record and all-time highest 24-hour snowfall.
