An atmospheric river will continue to bring gusty winds, moderate to heavy rainfall, and potential flooding to southern California and the southern Great Basin through Sunday. Periods of heavy snow will continue as well above 7,000 feet over the Sierra Nevada mountains associated with this atmospheric river. Read More >

Some users of NWS radar displays have begun receiving messages about the use of Adobe Flash in the display. Flash is scheduled to be discontinued toward the end of 2020, so web browsers have begun to alert users of this upcoming event.

The NWS's radar.weather.gov website has been the face of NWS radar data since 2003. The site routinely receives around 1.75 million hits on an average day and hundreds of millions of hits per day during active weather. The face of technology has changed dramatically throughout the last decade. By 2018 81% of Americans 13 years and older owned a smartphone. These devices have changed how and where we browse the internet. By 2018 mobile devices generated more than half of all web site traffic worldwide.

The radar web site is not mobile-friendly in its current form and some of the displays use Flash. So, in response to these dramatic changes, this spring the NWS will replace the existing site and features with the following:

Radar data and warnings presented on a dynamic map that allows zooming and scrolling
Radar data will include MRMS (Multi-Radar, Multi-Sensor) data in Quality Controlled (QCed) and non-QCed form, including rain/snow delineation
Increase in GIS services
Saving animations for use elsewhere (e.g. social media)

An example of the planned display is shown at right (subject to change).

In the meantime, we do have a non Flash-based version of the radar displays. This can be accessed from the regular radar page by clicking on the "Go to: Standard Version" link near the top left part of the screen. Or, you can use the following link:
