The way the NWS displays radar information on our websites will change dramatically on or around December 8, 2020.

Current radar display

New radar display (this URL will change when it replaces the current display on or around December 8)

 

The new display will replace the current FLASH-enabled display with HTML5 and Javascript within a web-based and mobile-friendly interactive map. Along with radar products, customers will also have the ability to overlay watches, warnings, and advisories. 

The web map will be optimized for small and large screen devices. Customers can bookmark a particular perspective of the map view or select and save a particular radar view.
