On July 7, 2015, NWS implemented changes to the icons depicted on all of its point-forecast pages. Changes include new icon images with increased clarity, 6-hour increments for rapidly changing weather and new color blocks to highlight forecast hazards.

A page depicting all of the new icon images can be accessed here: www.weather.gov/forecast-icons

Changes to the icons were based on analysis of 6,700 public comments collected in 2014. Also, many of these changes are based on the results of a research project led by the National Center for Atmospheric Research.

Users are encouraged to continue to provide comments regarding these changes via email at icons@noaa.gov. NWS will continue to analyze incoming feedback and refine the icons as necessary. Any substantial change to the icons will be facilitated through the NWS public comment/review process.
