Hazardous Weather Outlook product no longer displayed on national hazards map

NWS has made a change to the national hazard map, shown below, and will no longer be displaying the Hazardous Weather Outlook (HWO) product on the map. This change is intended to help users focus more quickly on the immediate impacts of hazards instead of those that are highlighted for the future. The Hazardous Weather Outlook will still be available on local Weather Forecast Office Web pages.
