 They also tended to be given relatively close to when the heat event started, so maybe two, three days. The new tool, which we call heat risk, is able to give a seven-day forecast that is health-based, meaning when you go up and increment on the scale, and there are four levels, there's green, yellow, orange, magenta. As you go up one level in that, it specifically means in that county that there has been observed increase in health effects from that increment.
