NWS PUEBLO Severe Weather Climatology Page
A "Severe Convective Weather Event" is defined as:
Hail = 3/4 of an inch in diameter or LARGER, and/or;
Wind Damage or Wind Speeds of 50 knots (58 mph) or STRONGER, and/or;
a Tornado.
Please note the following regarding severe hail:
The size of the largest hailstone determines if the storm is considered "severe" or not. The depth of the hail on the ground does not determine hail storm severity.
Example: You can have 4 inches of pea size (1/4") hail covering the ground, and this storm would not be considered severe. On the other hand, if you have 1 hailstone fall out of the sky that measures 4 inches in diameter, this storm would be considered severe.
Additionally, effective 01 April 2009, the definition of severe hail will change from 3/4" to 1.0". Please watch this PODCAST for more information.
Lightning is not considered "severe weather". If you wish to find out more about lightning in Colorado, please visit the NWS Pueblo Colorado Lightning Resource Page.
