Lightning Threat Zone

The Lightning Threat Zone product tracks storm cells using lightning data, and takes into account both speed and direction when computing the projected path and threat zones. It displays areas threatened by lightning 60 minutes into the future in 10-minute increments, which allows you to follow developing storm situations and plan accordingly.

Each 10-minute increment is displayed as a separate polygon, with a total of 6 polygons between the current time and one hour into the future. Each polygon is updated every 2 minutes.

The Lightning Threat Zone product is not displayed during animations due to the time it takes to render the threat zones.
