Recent U.S. Drought Monitor data valid September 29, 2026, and released October 1 show exceptional (D4) drought concentrated in central and eastern Texas, much of Oklahoma, and parts of Arkansas, driven by rapid-onset flash drought from persistent above-average heat and minimal rainfall through August and September. Southern states including Louisiana, Mississippi, and Tennessee have seen degradation into severe to extreme categories, while the High Plains and West recorded localized improvements from beneficial rains. The next USDM update, expected October 8 and reflecting conditions through early October, will incorporate any moisture from Hurricane Polo remnants alongside ongoing El Niño-related warmth across the southern U.S. Forecasters note that sustained deficits and high temperatures favor continued D4 coverage in the South, though model consensus on short-term rainfall could shift state-level outcomes.
