NOAA produces the Regional Snowfall Index (RSI) for significant snowstorms that impact the eastern two-thirds of the United States. The RSI ranks snowstorm impacts on a scale from 1 to 5, similar to the Fujita scale for tornadoes or the Saffir-Simpson scale for hurricanes.
Here you can access snowfall and snow depth statistics for several thousand non-airport stations in the National Weather Service (NWS) Cooperative (COOP) Network across the contiguous U.S. and Alaska. Data are available for daily, monthly, and seasonal snowfall and snow depth totals, which are useful in economic and engineering decision-making, and provide the Federal Emergency Management Agency (FEMA) with an objective basis for declaring federal snow disasters.
This online resource examines tornado activity across the United States across temporal and spatial scales. The contiguous United States is the most active tornado region in the world, with an average of 1,253 tornadoes occurring annually. The information and data provided here serves as a baseline for comparing current tornado activity to the past, providing a complete historical perspective.
When both temperature and humidity are high, humans can experience considerable heat stress. In the U.S., extreme heat may have greater impact on human health, especially among the elderly, than any other type of severe weather.
This online resource provides links to several NOAA online severe weather databases, including the Storm Events Database and the Severe Weather Data Inventory. These databases provide online access to files for storm and hurricane data in commonly used formats, such as shapefiles for GIS applications, KMZ for Google Earth, comma-separated values, and extensible markup language (XML).
Drought is one of the most costly natural disasters affecting the United States. The National Integrated Drought Information System (NIDIS) helps the nation and North America understand and proactively prepare for drought by providing data and information about the extent and potential impacts of drought and associated risks. The system provides a variety of decision support tools to help people prepare for and mitigate the effects of drought.
This NOAA National Climatic Data Center tool allows users to look up record-setting events for a given day, month, or all time. Specifically, users can look for record highest minimum or maximum temperature, lowest min/max temperature, precipitation, or snowfall. This information is available for individual U.S. states, U.S. regions, and U.S. territories.
NOAA's National Climatic Data Center issues monthly storm data containing a chronological listing, by states, of storm occurrences and unusual weather phenomena. Reports contain information on storm paths, deaths, injuries, and property damage. An "Outstanding storms of the month" section highlights severe weather events with photographs, illustrations, and narratives. Users may also search the NCDC Storm Event database to find various types of storms recorded in your county or use other selection criteria as desired.
A database of model clean energy projects implemented in 50 diverse communities across the U.S. highlighted by the Environmental Protection Agency. The site also contains tools and resources for communities looking to start greenhouse reduction projects on their own.
