Recent US Drought Monitor data valid through September 29, 2026, show exceptional (D4) drought intensifying across central and eastern Texas, Oklahoma, and parts of Arkansas, Louisiana, Mississippi, and Tennessee amid persistent above-average heat and minimal rainfall that has driven rapid-onset flash drought. The National Drought Mitigation Center and partners note D4 coverage expanding in the South Central and Lower Mississippi regions while improving across much of the High Plains and West due to beneficial precipitation linked to an intensifying El Niño. The upcoming USDM map for the week of October 6 will incorporate the latest 7-day precipitation, soil moisture, and streamflow observations; the NOAA Climate Prediction Center’s October outlook favors above-normal precipitation across the southern tier, which could limit further D4 expansion if realized, though short-term model consensus and any additional tropical moisture will determine final state-level thresholds.
