A weather service is an organization that provides forecasts and information about the atmosphere's conditions. They use various tools, such as satellites and radar, to monitor weather patterns and predict changes. This information helps people prepare for different weather events, like rain, snow, or storms. Weather services also issue warnings and alerts to keep the public safe during severe weather. They often collaborate with other agencies, such as National Oceanic and Atmospheric Administration (NOAA) in the United States, to ensure accurate and timely information is available to everyone.
