NWS Pueblo Lightning Page - County CG lightning

County by County flash information

The map (below) shows the estimated number of Cloud-to-Ground (CG) lightning flashes (in thousands) which occur in each county in Colorado per year. These values were gathered by estimating the average flash density for each county, and then multiplying this value by the size of the county. Gilpin and Denver counties had values of 1.6 and 1.2 respectively. The new county of Broomfield is not in this data set, and there are no plans in the immediate future to include this new county.
