Which Official Source Answers Which Question?
Many weather sites repeat the same data. These are the original sources, and the one question each answers best.
| Your question | Best source | What to look for |
|---|---|---|
| Is there a warning for my county right now? | weather.gov | Enter your ZIP code; warnings appear in red at the top. A SAME weather radio gives the same warnings without internet. |
| Will storms be severe today or tomorrow? | SPC convective outlook | Five risk levels: 1 Marginal, 2 Slight, 3 Enhanced, 4 Moderate, 5 High. Level 3 and up means organized severe storms are likely in that area. |
| Where is the hurricane going? | National Hurricane Center | The cone shows the likely path of the storm center only. NHC sizes it so that about two-thirds of past forecast errors fall inside it, so roughly one time in three the center tracks outside it. Wind, surge and rain reach far beyond the cone. |
| What is the rain doing in the next hour? | NWS radar | Loop the last hour to see direction and speed; see our radar guide for the colors. |
| How much rain really fell near me? | CoCoRaHS | Daily manual readings from volunteers with standard 4-inch gauges, often closer to you than an airport station. |
| What is the weather on my street? | Weather Underground personal stations | Compare two or three nearby stations: a single home station can be badly placed. |

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.
