Interactive Radar Help & FAQ

I'm having trouble using the interactive radar on my smartphone.

The new Klystron 9 Interactive Radar is made for use on desktop, laptop and tablet devices. A new mobile app with radar optimized for your smartphone is coming soon to Apple's App Store and Google Play.

It is still possible to use the new Interactive Radar on your phone by entering in your ZIP code in the searhc bar. That will allow you to zoom in to your location. The new Interactive Radar is built using HTML5, so it can be viewed on any operating system.

What happened to the old map's dark green and blue colors?

We are working on revamping the color to match our look on TV, with dark green land and dark blue water, to make the interactive radar easier for you to view and decipher.

I don't see a map. I only see a gray box where the map should be in the interactive radar.

Make sure your computer's clock is accurate. If it's off by about an hour, your browser's requests for the interactive radar will not succeed, and you'll either receive a gray image or a 403 Forbidden error, depending on your browser.

I can't view the interactive radar in Internet Explorer.

The new Interactive Radar is not compatible with Microsoft Internet Explorer 8 (IE 8) or below. Please upgrade to the latest version of the browser, Internet Explorer 11, for optimized viewing of our radar and most websites across the Web.

What are the differences between Klystron 9, NWS Radar and NWS Local Radar?

NWS Local Radar shows data from the National Weather Service in Ruskin.

NWS Radar is the National Weather Service's data for the entire U.S. You can zoom out to view radar over the rest of the country, but this may be less accurate if you're looking at local conditions.

Klystron 9 is the most accurate option for viewing local radar in the Tampa Bay area.
