The last zero reading for exceptional drought in Texas was late March 2011. Until Thursday, according to the weekly U.S. Drought Monitor map.
Only 6.3 percent of Texas is in extreme drought, the lowest figure since it was at 5.2 percent in December 2010. The percentage of the state in severe drought rose slightly over last week.
About 10 percent of the state is drought-free, most of that in North Texas. Local counties not listed as drought-free lie mainly along the Red River, including Delta, Fannin and Lamar, who are in the abnormally dry stage.
