Maine enters the weekend facing a statewide drought affecting 100 percent of the state, according to data issued on September 24. Drought Monitor. While dry conditions persist, a long-duration rain event is expected to bring beneficial moisture starting September 27 and continuing through September 29, offering potential relief for parched soils, rivers, and streams across the region. The latest drought monitor figures show no change compared to the preceding week. Extreme drought conditions remain entrenched across Midcoast Maine and extend upward through Bar Harbor. Meanwhile, severe drought conditions persist across several major population centers and cities, including Portland, Augusta, and Bangor.
Drought Severity Compared to Three Months Ago
The current widespread dryness marks a sharp escalation from conditions earlier in the year. On June 23, approximately 8% of Maine was experiencing dry conditions. By September 24, that figure reached 100% of the state. About 25% of the state currently sits within at least a severe drought classification.
Expected Rainfall and Hydrological Impact
Meteorological forecasts indicate that a steady, long-duration rain event will begin arriving over the weekend, with the steadiest precipitation falling from late Saturday, September 27, through Monday night, September 29. Several inches of total rainfall are projected for many areas by the end of the storm cycle on September 29. According to regional forecasts, this type of steady, light-to-moderate rainfall provides greater benefits during a drought than intense downpours. The prolonged timing allows for better ground absorption and significantly reduces surface runoff compared to heavy rain generated by thunderstorms. The incoming moisture is also expected to help refill depleted rivers and streams throughout the state.
