Washington, District of Columbia – Rainfall deficits exceeding 2.5 inches since December are prolonging drought concerns along the Interstate 95 corridor.
According to the National Weather Service Eastern Region, Washington has recorded 3.61 inches of precipitation since Dec. 1, 2025 — a 2.53-inch deficit compared to seasonal averages.
Despite several winter storms bringing rain and occasional snowfall, overall liquid-equivalent precipitation remains below normal. The latest U.S. Drought Monitor continues to indicate moderate drought conditions across parts of the Mid-Atlantic, including areas surrounding the District.
Officials say extended dryness dating back to late summer has contributed to reduced soil moisture and lower streamflows in portions of the Potomac River basin. Reservoirs and groundwater supplies are being monitored as the region approaches the spring recharge period.
Drivers along Interstate 95, Interstate 395, Interstate 66, Interstate 295, and Interstate 495 may notice lower water levels in creeks, retention ponds, and tributaries near roadways.
While periodic rainfall is expected later this season, forecasters caution that sustained above-normal precipitation would be required to significantly reduce longer-term deficits.
Outdoor workers, landscapers, and municipal water managers continue monitoring soil and water conditions as winter progresses.
Residents are encouraged to practice water conservation and stay updated as drought classifications are reviewed in the coming weeks.
