USAGE:If your mouse is pointing at the map, the map stops changing. You can manually move to the next or previous map by using the arrows that appear. Move your mouse off the map to have the maps automatically progress. Point your mouse at the small gauges located on the lower left corner to get large interactive gauges where you can actually change what the gauges display. Want your temperature in Celcius? Want to see the wind chill instead of the heat index? How about the wind in Knots. You are in control. Change the gauges here and your changes are saved for the rest of the site, even the next time you visit!
