In order to predict the weather, the NWS uses a variety of data sources – including satellites, weather balloons, buoys, radar, and more. From this data, supercomputers are able to help create accurate models for extreme weather hazards like hurricanes, tornadoes, and heat waves.
By using powerful computers, the NWS is able to make predictions well in advance of any weather event. This allows communities and businesses plenty of time to prepare for potential dangers. And thanks to our ever-expanding network of sensors, the NWS is always keeping track of shifting patterns and new threats in the weather world.
