National Oceanic and Atmospheric Administration

Site Thumbnail - National Oceanic and Atmospheric Administration (NOAA)

Many of the best resources about weather and climate come from NOAA. The front page of NOAA contains the latest news articles from NOAA. We couldn't begin to cover all the other areas of NOAA here.
Site Thumbnail - Weather.gov - National Weather Service (NWS)

The front page displays a map of all the current watches, warnings and advisories across the United States. If you click your area on the map, you can visit your local Weather Forecast Office. You can enter your zip code for current, and forecast, conditions for your area.
Site Thumbnail - Quantitative Precipitation Forecasts (QPF) from the Weather Prediction Center

View images showing the forecast rainfall for the Contiguous United States for the next 1 to 7 days.
Site Thumbnail - North American Surface Analysis from the Weather Prediction Center

View the latest surface analysis, with fronts, highs and lows. You can view an interactive version of the map here.
Site Thumbnail - Advanced Hydrologic Prediction Service (AHPS)

View current, and forecast, river levels across the United States.

U.S. and International Weather Forecasts

    Like you can at Weather.gov, each of these sites let you enter your location for a detailed forecast.

  • Weather Underground
    Their site also has an interactive map, called the WunderMap, which has weather observations, radar, satellite imagery and other features.

    They also have historical data for weather stations around the world. They have data from over a quarter of a million weather stations.

    Weather Underground is owned by The Weather Company, a unit of IBM, which also owns Weather.com.
  • Weather.com

    The Weather Company, part of IBM, owns Weather.com. Some content on this site also comes from The Weather Channel, which is actually owned by a different company.
  • AccuWeather

    This site features extended forecasts for locations that go well beyond the 7 to 10 days of most other sites. While you might infer a possible trend in the data, such as above or below average temperatures or an increase or decrease in rainfall, which may or may not be accurate, you should probably avoid using it for any other purpose.

Various Tools

  • Current Cyclone Generation Probability
    This is a computer generated product. It is an interesting product, but the percentages might be very incorrect. The images on the main page are interesting to determine trends. The bottom of the page has graphs that allow you to compare the year-to-date observations to the average over that period.
  • Advanced Dvorak Technique (University of Wisconsin-Madison | NOAA)
    ADT gives an estimate of the wind and pressure of a system. It can help you determine if a storm is weakening or strengthening. It can also be helpful to find the center of a storm. A satellite image of the storm will show the estimated position. This resource is for developed tropical cyclones only. For invest areas, as well as developed storms, see NOAA's Tropical Storm Position Page. Once you get the CI number, use the Dvorak chart to determine the estimated intensity of the storm.
  • Satellite Consensus Intensity Estimates (SATCON) from University of Wisconsin-Madison (About)
    This is another technique that gives intensity estimates for storms. This is nice because it gives other satellite intensity estimates as well.
  • Advanced Microwave Sounding Unit (AMSU) from University of Wisconsin-Madison (About)
    This is another technique that gives intensity estimates for storms. Once you are on a storm page, click "Current Intensity" in the top left corner for text data.
  • United States Drought Monitor
    Weekly images showing current drought conditions across the U.S.
  • Dvorak Current Intensity Chart
    If you know what the CI number is, or the surface pressure of a storm, you can get an estimate of what the wind speed might be using this table. The NHC says this on that page: "Note that these are intensity estimates and may be superceded by reconnaissance and/or surface observations." Please keep that in mind when using the chart.
  • Climate Prediction Center Hurricane Outlook
    This site details what NOAA expects of the hurricane season. It is important to note that "This outlook is a general guide to the expected overall activity during the hurricane season. It is not a seasonal hurricane landfall forecast, and it does not predict levels of activity for any particular location."

    Whether a season is forecast to be above, near or below average, it only takes one storm to potentially change your life. If a season is below average, that doesn't matter if you were one of the people impacted by a storm in that season. You should always prepare for each season regardless of what seasonal forecasts say.

Educational Information

Other Sites About Hurricanes

  • Atlantic Hurricane Seasons from Wikipedia
    One of the best resources for finding information about past hurricanes, and their impacts, is Wikipedia. You can verify the information it contains by looking at the references listed. There is likely no better site for viewing all of this data in one place. Select a year to view information about storms from that year.
  • Hurricane City
    This site has a city database that has information about storms that have impacted those cities. Also be sure to check out the message board, CaneTalk, which we help to administer.
  • Storm2K.org
    This site is a great message board with quite a few knowledgeable weather professionals.
