Understanding Weather Alerts: Staying Safe in Severe Conditions
Weather alerts are critical tools that help protect lives and property by providing timely warnings about potentially dangerous weather conditions. These alerts, issued by meteorological agencies like the National Weather Service (NWS), come in various forms and levels of urgency.
