Information on Access to NEXRAD (Weather Radar) data...

The National Weather Service is working on a new public-facing webpage to view radar data.  You can view the new “preview” radar page ( to familiarize yourself with the format and features.  The new GIS-based webpage is an updated way to access and view radar data, from the national mosaic of Multi-Radar Multi-Sensor (MRMS) derived base reflectivity and select Dual-Polarization products.  The new page was redesigned to improve the National Weather Service radar services based on feedback received over the past several years, and the upgrade will also move the agency off the soon-to-be-obsolete Adobe Flash technology used in the current pages for radar loops.

Among the new features are:

  1. The new webpage is a GIS-based webpage for easy integration into GIS applications used for situational awareness.
  2. It will provide radar images more frequently and at four times higher resolution than currently provided.
  3. The new mobile friendly format allows you to monitor the weather while you are on the go.

The new radar webpage will replace the current page on or about December 16, 2020.  Through December 15th, the new webpage will run in parallel with the current one, in order to allow users the necessary time to transition to learning the new interactive radar webpage.

An FAQ page ( includes answers to some common questions and other information on enhancements with the new page.  This page will continue to be updated over time with new information as it is deemed necessary to add.
