things you should know about this experimental live-updating page

  1. Warnings are delayed. If you are currently affected by severe storms, you should also be paying attention to a local source of information (tv, radio, etc), or have a weather radio, because information on this site can be delayed enough that it could cause you to lose valuable lead time.
  2. The map sometimes breaks in odd ways. At this time, I'm not sure of the actual cause, but every so often, the mapping software will basically lose track of the actual center of the map. It's most obvious when part of the map is black (it's not loading the background). Also, you may notice this bug when you zoom to a specific location or warning, and the map is not centered properly.
  3. How to fix: The easiest thing is to reload the page. Otherwise, you can try the following to get the map to fix itself:

    1. enter/exit fullscreen map mode
    2. resize the browser window (if a desktop)
    3. change the orientation of the screen (if a tablet/mobile device)
    4. add a new location marker (you can delete the new marker later)

  4. There is experimental voice notifications support. To my knowledge, this only works in the Chrome and Safari browsers. Chrome's default English voice will randomly stop with long text, so I've tried to break up the text into smaller chunks so this doesn't happen. However, this can lead to awkward pauses when it's speaking.
  5. There is now support for tracking custom locations. If you have voice notifications enabled, it will tell you which locations are impacted when it reads new warnings.
  6. Radar on the map will automatically refresh every 5 minutes.
  7. This page is under active development. And things tend to break. A lot. If you think something is wrong, you can reload the page. You can also use the normal severe weather map page which has the same data but does not automatically update.

Remember to check out severe weather outlook for more severe weather and cyclocane for hurricanes.
