Other regions in the state are categorized under 'Extreme Drought' (D3), with SPI values ranging from -1.9 to -1.
These classifications are derived from a combination of precipitation and moisture indices, compared to historical data from 1979 to the present.

Impact & Risks

The ongoing drought in Pennsylvania poses risks to agriculture, water supply, and ecosystems. Exceptional drought conditions (D4) can lead to widespread crop and pasture losses, water shortages, and heightened fire risks. Extreme drought (D3) conditions may also strain water resources and impact local communities. These conditions could trigger disaster declarations and affect loan eligibility for farmers and businesses. The state may need to implement water conservation measures and adjust water supply planning to mitigate the impacts.
