The National Weather Service (NWS) is a subdivision of the National Oceanic and Atmospheric Administration (NOAA), which is an agency within the United States Department of Commerce. It is the nation’s official source of weather information. The NWS’s primary responsibility is providing weather forecasts, warnings, and other weather-related services to the public. The NWS plays a crucial role in safeguarding lives and property as the office collaborates with emergency management agencies, the media, and private industries to ensure that the public receives good weather information in a timely manner. The NWS disseminates weather warnings and advisories through a wide variety of communication channels, such as radio, television, websites, and mobile apps.
The NWS gathers and analyzes weather data from various sources, including a vast network of satellites, airplanes, radar, surface weather observations, and ocean buoys. These data, along with computer models, enable meteorologists at NWS to generate accurate and up-to-date weather forecasts, severe weather advisories, and warnings across the United States. The NWS includes a network of local weather forecast offices throughout the country. These offices have trained meteorologists who monitor regional weather conditions and generate accurate timely weather forecasts and alerts as needed.
These NWS forecasts and weather alerts are accurate, widely available and free to the public. They impact everyday life. These forecasts also support industries that rely on weather forecasts. Private industries, including TV forecasters, AccuWeather, and the Weather Channel, all use NOAA data and NWS forecasts. NOAA and NWS provide weather and climate data and forecast models that are a national treasure. The weather and climate models produced continuously by the NWS are accurate and robust. It is impossible and inefficient for private industry to provide comprehensive weather data in a reliable way that is also freely accessible to everyone.
