Top of Page National Overview

  • A file containing the national monthly percent area severely dry and wet from 1900 to present is available for the severe to extreme and moderate to extreme categories.
  • Historical temperature, precipitation, and Palmer drought data from 1895 to present for climate divisions, states, and regions in the contiguous U.S. are available at the Climate Division: Temperature-Precipitation-Drought Data page in files having names that start with "drd964x" and ending with "txt" (without the quotes).

Top of Page Detailed Drought Discussion

At the end of February extreme hydrologic drought was concentrated in Texas, Wyoming, and northern Minnesota. Drought and abnormal dryness covered a broad swath from central and southern California through the northwestern Plains into the upper Midwest (February 27 Drought Monitor). Drought and abnormal dryness continued in Florida and increased in the central and southern Appalachians. In southern California and the upper Midwest, soil moisture was low. Vegetative health had become more stressed in the West. Streamflow was low in the East, especially in Tennessee, in parts of the Plains, and in Wyoming.

In Texas and Florida mandatory or voluntary water restrictions were in place in several municipalities. Private water wells were becoming dry in Texas. Burning bans were common in drought-stricken areas, and wildfires reduced forage in western Nebraska and increased in number in Florida. The hay supply in the central part of the country was 20 percent of average, leading to increased prices and abnormal selling of livestock at auctions. The killing of livestock and pets by wild animals in southcentral Texas increased as the wildlife searched for new food and water sources during the continuing drought. Dryness has increased the salinity of Virginia's James River and the Chesapeake Bay permitting the growth of parasites that are harmful to oysters; in some areas the oyster death rate was 90 percent. Impacts in drought-stricken areas have been collected and summarized by county at the National Drought Mitigation Center's Drought Impact Reporter.
