Data News Item: New maps and data now available for the Absolute Threshold Heat Index Days from the CDC National Environmental Public Health Tracking Network, 2022. ***PREM***

Data have been updated from 2011 annual count via CDC WONDER to 2019-21 three-year average count via CDC National Environmental Public Health. Maps are updated accordingly to reflect this change. We made this change because the old version has not been updated since 2011. Note that the new report fields are different than the previous report.
