Drought conditions have returned to much of the Desert Southwest and southern Plains due, in part, to a dry winter that left the land parched in several states.Using data from the U.S. National Drought Monitor, NASA compiled a map that shows the areas of the country that have fallen back into some of the worst drought categories just nine months after 95 percent of the nation was drought-free. The map, using data acquired Feb. 27, shows extreme drought taking over parts of Texas and the Desert Southwest, with moderate or severe drought seen in the Southeast, northern Plains and parts of California.
