TreeFlow is a comprehensive web resource for tree-ring reconstructions of streamflow and climate, providing easy access to reconstruction data as well as information about how the data were developed, and can be used. Originally developed by researchers at the Climate Assessment for the Southwest, TreeFlow has a growing collection of tree ring constructions for river basins throughout the Western United States.
The WestMap toolbox is an interactive web-based interface developed by the Climate Assessment for the Southwest in response to findings that stakeholders in the Western U.S. from a wide range of sectors require new forms of data, intuitive tools, and support resources to understand climate variability and to be able to incorporate this understanding into specific planning and management efforts. The toolbox includes a lengthy time series of fine-scale (~1-4 km) gridded climate data that can be aggregated to user-specified domains as well as helpful climate education information.
Cal-Adapt is a web-based climate adaptation planning tool developed in part by the University of California, Berkeley's Geospatial Innovation Facility for the State of California.

Paleoclimate Reconstructions for the Southwest
The longest instrumental climate records date back only about 100 years in the Southwest, a timeframe that likely does not capture the full range of climate variability. Extending the record to earlier times provides additional information on the length and severity of past droughts. This tool created by the Climate Assessment for the Southwest allows users to visualize the climate variability during the past 1,000 years or so in each climate division in Arizona and New Mexico.
Historical Hurricane Tracks
This interactive mapping application easily searches and displays global tropical cyclone data. Users are able to query storms by the storm name, Zip Code, city, state, geographic region, or latitude/longitude coordinates. Custom queries can track storms of interest and allow for data extraction and download.
CanVis is a visualization program used to see potential impacts from coastal development or sea level rise.

National and Local Weather Hazards
The National Weather Service provides weather, water, and climate data, forecasts and warnings for the protection of life and property and enhancement of the national economy. These products include forecast and warnings of environmental events that can impact human health, such as excessive heat, flooding, severe cold, and more.
U.S. Heat Stress Index
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. The combined effects of temperature and humidity cannot be directly measured but can be assessed by calculation of an "apparent temperature." This index of “how hot it feels” should not be confused with the Heat Index used by NOAA's National Weather Service because the latter index is not defined for temperature below 80°F (27°C) and relative humidity below 40%.
U.S. Drought Monitor
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 information is available for individual U.S. states, U.S. regions, and U.S. territories.
Heat Index Forecasts
Heat index products are issued from the medium-range forecast function of the Hydrological Prediction Center for days 3 through 7 during the period from May 1 through September 30. With the exception of day 3, these products are based on an ensemble of model and human forecasts. Graphic plots display the cities for which the heat index forecast is interpolated, as well as shaded contours indicating the probability of the daily maximum, daily minimum, and daily mean heat index reaching or exceeding a specific threshold.
Coastal County Snapshots
Coastal County Snapshots turn complex data into easy-to-understand stories, complete with charts and graphs. Users select a coastal county of interest and the website does the rest, providing information that can help communities become more resilient to coastal hazards.
Local officials can use the snapshots as a planning tool to assess their county’s resilience to flooding and understand the benefits provided by natural resources. The handouts generated by the snapshots can be a helpful educational tool when working with governing bodies and citizen groups.Current topics include flood exposure, wetland benefits, and ocean and Great Lakes jobs.
A tool that provides a flexible capability for creating user-determined climate change scenarios for assessing the potential impacts of climate change on sediment loading to streams using the the U.S. Department of Agriculture's Water Erosion Prediction Project (WEPP) Model.
