HeatRisk (www.wpc.ncep.noaa.gov/heatrisk/) is used to trigger the issuance of Excessive Heat Watches & Warnings. In general, High or Very High HeatRisk signals that unusually hot weather is expected and outdoor activities or running errands are not "business as usual." #HeatAwareness pic.twitter.com/z6bFyXWkOX
