TreeFlow

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.

Arizona DroughtWatch

Arizona DroughtWatch is a tool designed by the Climate Assessment for the Southwest to collect, summarize, and display timely observations of drought impacts across Arizona. The tool was developed to support drought monitoring efforts spearheaded by county-level Local Drought Impact Groups organized in support of the Arizona State Drought Preparedness Plan.

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.

Southwest Climate Outlook

The Climate Assessment for the Southwest puts out monthly outlooks for the region. These outlooks include a look at last month's temperature and precipitation data, the current state of El Niño/La Niña and reservoir levels, and forecasts for temperature, precipitation, and streamflow. Additional seasonal sections of the outlook include wildland fire and snowpack updates. Archives are also available online.

For the first time in four years, no area of the country faces a high risk of major to record spring flooding, largely due to the limited winter snowfall, according to NOAA's annual Spring Outlook...

Drought Impact Reporter

The National Drought Mitigation Center launched the Drought Impact Reporter (DIR) in July 2005 as the nation’s first comprehensive database of drought impacts. DIR collects and displays drought impact information for the U.S., providing researchers and interested members of the public with more context and detail on drought, as well as more readily summarized information.

While wet and snowy weather has dominated the western U.S., persistent drought conditions are likely to linger in the Southern Plains and Southeast through mid to late spring, according to NOAA's...
