The National Weather Service is taking comments on the experimental Graphical Hazardous Weather Outlook (GWHO) through April 30. The GHWO is a convenient method to assess potential weather hazards that could affect your work or the safety of residents and employees. The web page (https://www.weather.gov/erh/ghwo?wfo=unr) shows seasonal hazards on a map and in a table with clickable buttons. The buttons are colored for the highest risk associated with that hazard across our forecast area for the next seven days; clicking on a button will display the forecast area map for that day.

To provide comments take the survey at https://www.surveymonkey.com/r/Exp_GHWO_2022_23

Additional details are included in the Product Description Document at: https://nws.weather.gov/products/PDD/PDD_GHWO_ExpExt2022.pdf

At the end of the comment period, if feedback is favorable, the product will be evaluated for continuation or operational implementation.
