Best Sources for Weather Data and Unbiased Weather Information

Whether you are searching for potentially life-saving weather information, a local forecast, or even historical weather data, there are a number of government and private weather sites that you can visit.

Since your tax dollars fund government weather organizations such as the National Oceanic and Atmospheric Administration (, I will focus on some of their useful sites. Dedicated meteorologists, using the latest forecast guidance, satellite and radar products, and other tools, work around the clock to analyze, assemble, and communicate this critical information.

National Hurricane Center

The National Hurricane Center, located at Florida International University in University Park, Florida, is responsible for tracking and predicting tropical weather systems. This includes the entire Atlantic Basin and the eastern Pacific Ocean. This site is easy to navigate, and some of their main products are highlighted below.

  • Daily tropical weather discussions and tropical weather outlooks are issued (during the hurricane season). Tropical weather outlooks are also produced, in graphical form, along with percent chance of tropical cyclone formation for 48-hour and 5-day periods. These discussions are for the entire Atlantic Basin (which includes the Caribbean) and the eastern Pacific (Hawaii is covered by the Central Pacific Hurricane Center, while the western Pacific (including Guam) is covered by the Joint Typhoon Warning Center.
  • Tracking of all tropical cyclones (including tropical depressions, tropical storms and hurricanes) and forecast intensity and track (come) for each system.
  • Frequent advisories on all tropical cyclones, including all watch and warning areas.
  • Satellite and some radar data around the tropics and for all tropical cyclones.
  • Updated recon info from Hurricane Hunter Aircraft, including vortex data, on tropical cyclones.
  • Track history of former tropical cyclones can also be found here.

Storm Prediction Center

The Storm Prediction Center is located at the National Weather Center in Norman, Oklahoma. Their primary responsibility is to forecast the risk of severe thunderstorms and tornadoes across the United States. They accomplish this task in a variety of ways and some of the products that are available are listed below.

  • Convective outlooks are issued several times a day. These are both probabilistic and categorical forecasts which cover Day 1 through Day 8. The categorical risks indicate that probability of thunderstorms, including: general thunderstorms (light green), marginal (dark green), slight risk (yellow), moderate risk (red), and high risk (magenta).
  • Mesoscale discussions highlight areas where a severe thunderstorm or a tornado watch could be issued in the near future. Discussions for heavy snow potential are also issued.
  • All severe thunderstorm and tornado watches are issued by the Storm Prediction Center.
  • Current and past storm reports (severe weather including wind, hail, and tornadoes) can be easily accessed.
