Quick answers to the most common questions about weather tools and data sources
What are the best weather resources?
The most reliable free weather resources are NOAA's weather.gov for official forecasts and warnings, radar.weather.gov for Doppler radar, the Storm Prediction Center for severe weather outlooks, and Weather Underground for hyperlocal personal station data. For hurricane tracking, the National Hurricane Center at nhc.noaa.gov is the definitive source. Our Weather Education hub covers how to use all of these tools effectively.
What is NOAA used for?
NOAA, the National Oceanic and Atmospheric Administration, is the US government agency responsible for monitoring and forecasting weather, climate, and ocean conditions. It operates the National Weather Service, issues all official storm warnings and watches, runs the NOAA Weather Radio All Hazards broadcast network, and provides free public access to satellite imagery, Doppler radar, and historical climate data.
What is the most accurate weather website?
For official accuracy, weather.gov (National Weather Service) is the most authoritative US weather website since all other services ultimately use NWS data. For hyperlocal conditions, Weather Underground is typically more accurate than national apps because it draws from thousands of nearby personal weather stations. For radar, radar.weather.gov provides the same Doppler data used by professional meteorologists at no cost.
Where can I check live weather radar?
The best free live weather radar sources are radar.weather.gov (official NOAA Doppler radar), Weather Underground, and the RadarScope app for mobile. Our guide on how to read weather radar explains what the color bands mean, how to spot storm cells and rotation, and how to interpret velocity data for wind speed estimates.
