The High Plains Regional Climate Center’s Water Deficit Trends tool provides information on long-term changes in precipitation across the country.

The National Weather Service Weather Prediction Center's Day 3–7 Hazards Outlook shows potential hazardous conditions related to precipitation/flooding, temperature, wildfire/winds, and soils/drought. 

OWWLS, Overview of Weather Water Land Sites, maps the location of weather stations, streamgages, groundwater monitoring stations and reservoirs across the United States, Puerto Rico, and the U.S. Virgin Islands. 

The US Gridded Standardized Precipitation Index (SPI) is derived from the nClimGrid-Monthly dataset and includes timescales of 1, 2, 3, 6, 9, 12, 24, 36, 48, 60 and 72 months.

The Multi-Radar Multi-Sensor System combines data streams from multiple radars, satellites, surface observations, upper air observations, lightning reports, rain gauges, and numerical weather prediction models to produce a suite of decision-support products every two minutes.

The Climate Prediction Center's Day 8–14 (Week 2) U.S. Hazards Outlook shows potential hazardous conditions related to temperature, precipitation, wind, snow, and rapid onset drought.

 The U.S. Drought Portal's Historical Data & Conditions Tool displays three historical drought datasets side by side on an interactive time series graph and map: U.S. Drought Monitor (2000 - Present), Standardized Precipitation Index (1895 - Present), and Palmer Modified Drought Index (0 BCE - 2017). These data are available for download in CSV, XML, and JSON format.

The United States Gridded Standardized Precipitation Evapotranspiration Index (SPEI) is derived from the nClimGrid-Monthly dataset and includes timescales of 1, 2, 3, 6, 9, 12, 24, 36, 48, 60 and 72 months.  The nClimGrid-monthly dataset is a gridded dataset derived from spatially interpolating data from the Global Historical Climatology Network (GHCN), starting in 1895.

The Navajo Nation Drought Severity Evaluation Tool (DSET) is a co-developed cloud-based web application designed to meet the needs of water resource managers from the Navajo Nation, improving drought reporting and management.

The Southern Regional Climate Center Dashboard provides climate data products for the Southern U.S., including Arkansas, Louisiana, Mississippi, Oklahoma, Tennessee, and Texas.
