Interactive radar maps let you watch the weather (pictures)

Select a location to view the severity of approaching storms and recent lightning strikes, along with color-coded boxes for tornado warnings, thunderstorms, and flood warnings.

Show as much or as little info as you want with an extensive list of weather layer options.

In this screenshot, you can see two blue-lined shapes near San Antonio and Austin that signify severe thunderstorm warnings in those areas.

Go into the settings for everything from layer management and severe weather alerts to forums where you can talk with other people about approaching storms.

Bookmark your family and friends so you can check to make sure they are safe during big storms.
