Lightning Activity in the Western States

BOULDER, CO--(Marketwired - Jun 13, 2013) - Are you Weather-Ready? Lightning Safety Week starts on June 23!

Vaisala's (HEX: VAIAS) U.S. National Lightning Detection Network (NLDN) has been operational for over 30 years, and has the longest archive of lightning data. Statistics from this unique dataset provide a comprehensive view of lightning activity over the United States, which is highly valued for lightning safety, risk management, and severe weather analysis.

In the western U.S., the highest average lightning frequency is in New Mexico, Arizona, and Colorado. Storms occur on the southeast Plains in May and June, but in other regions mostly during July and August. Most of the lightning starts around mid-day over the higher terrain moving outward to lower regions in the afternoon and early evening. The attached PDF document shows a lightning density map, lightning fatality numbers, and insurance claims. The same information is also available for other regions of the United States.
