About Severe Weather Risk Analysis

This severe thunderstorm analysis overview covers just about everything you can imagine about a severe weather event, all in one graphic.

First, there’s a threat bar for the SPC Outlook for the day you’re creating a forecast for. Next, you can add watch likelihood for tornado watches and severe thunderstorm watches. Then, you can enter the threats for specific severe threats: tornadoes, damaging wind, large hail, and flooding.

Lastly, you can embed a outlook map as well as a synopses of the event under the event forecast map.
