The National Weather Service relies on trained volunteers to supplement doppler radar information on severe storms and tornadoes. These dedicated individuals volunteer their time to learn about and detect severe weather. Their valuable cooperation is important in the warning process. Weather reports from trained spotters are used along with doppler radar data to issue warnings of tornadoes, severe thunderstorms, and flash floods.

This spring, we are providing a series of videos highlighting all aspects of the spotter training. The video series will be released through late April and May.

Part 1: An Introduction to Our Local Spotter Training Program
