A weather forecast is a prediction about the atmospheric conditions in a specific area over a certain period. It typically includes information about temperature, precipitation, wind speed, and humidity. Meteorologists use various tools, such as satellites and radar, to gather data and create these forecasts. Weather forecasts can be short-term, covering a few hours to a few days, or long-term, extending up to several weeks. They help people plan their activities and prepare for different weather conditions. Reliable forecasts are essential for agriculture, transportation, and emergency management, ensuring safety and efficiency in daily life.
