New Heat Warning System Adds Magenta for Most Extreme Conditions

The National Weather Service and the Centers for Disease Control and Prevention have launched a new heat risk system that uses a seven-day forecast and a color-coded scale to alert Americans to dangerous heat conditions. The system includes five categories: pale green (little to no risk), yellow (minor risk), orange (moderate risk), red (major risk), and magenta (deadliest risk). The system is based on science-set numerical thresholds that take into account local weather data, climatology, and health data. Heat is the number one weather-related cause of death in the United States, and the new system is designed to help reduce deaths by providing better warnings and planning tools.

New Tools Unveiled to Safeguard Americans from Extreme Heat Risks

The National Oceanic and Atmospheric Administration (NOAA) and Centers for Disease Control and Prevention (CDC) have collaborated to develop a suite of resources to protect individuals in the United States from the escalating dangers of extreme heat. These resources include color-coded heat forecasts, a public dashboard displaying local heat risks and air quality levels, and guidelines for healthcare professionals on educating patients about heat-related illnesses. The initiative aims to raise awareness among vulnerable populations and provide them with tools to prepare for and cope with heat waves.
