What drought has meant in Pennsylvania

The National Drought Mitigation Center's examples of impacts observed in Pennsylvania at each level of drought.

D0 Abnormally dry

  • Crop growth is stunted; planting is delayed
  • Fire danger is elevated; spring fire season starts early
  • Lawns brown early; gardens begin to wilt
  • Surface water levels decline

D1 Moderate drought

  • Honey production declines
  • Irrigation use increases; hay and grain yields are lower than normal
  • Trees and landscaping are stressed; fish are stressed
  • Voluntary water conservation is requested; reservoir and lake levels are below normal capacity
  • Wildfires and ground fires increase

D2 Severe drought

  • Fish kills occur; wildlife move to farms for food
  • Golf courses conserve water
  • Producers begin feeding cattle; hay prices are high
  • Specialty crops are impacted in both yield and fruit size
  • Trees are brittle and susceptible to insects
  • Warnings are issued on outdoor burns; air quality is poor
  • Water quality is poor; groundwater is declining; irrigation ponds are dry; outdoor water restrictions are implemented

D3 Extreme drought

  • Crop loss is widespread; Christmas tree farms are stressed; dairy farmers are struggling financially
  • Extremely reduced flow to ceased flow of water is observed; river temperatures are warm; wells are running dry; people are digging more and deeper wells
  • Water recreation and hunting are modified; wildlife disease outbreak is observed
  • Well drillers and bulk water haulers see increased business

This week in the Northeast

The Drought Monitor authors' narrative for the map of Sep 15, 2026, released Sep 17, 2026.

Northern New Jersey to Cape Cod along the coast of southern New England had a band of significant rain in the past week. Unfortunately, this rain was not where it was most needed. Much of Maine saw deteriorating drought conditions with continued dryness. An area of extreme drought was introduced along the Maine coastline, with low streamflows and well levels observed. Another area with rain falling over locations that are not abnormally dry was in West Virginia and western Pennsylvania.

Looking ahead

Over the next five days leading up to next Tuesday, above normal rainfall is forecast in south Florida as well as a large area in southern Wisconsin and Minnesota into eastern Iowa and northern Illinois. The latter area of forecasted rainfall continues to the east through central Michigan, the southern Great Lakes, Pennsylvania, New York, and much of central and southern New England. Other locations with rainfall in the forecast this week are in the Appalachian Mountains, the western Great Plains, and the Four Corners states. Unfortunately, most of Texas, Oklahoma, Arkansas, Louisiana, Mississippi, and Alabama are forecast to receive little rainfall. Dry conditions are also forecast in California, Nevada, and Washington. Much above normal temperatures are forecast to continue this week in the central and southern U.S.

The 6- to 10-day outlook (September 22-26, 2026) favors above normal temperatures continuing over nearly all of the continental United States. Areas most likely to be above normal are again the south into the southeast, plus the far north. Hawaii is also likely to be above normal. For precipitation, the Eastern Seaboard is likely to have above normal rainfall as is the Southwest. The central U.S. into the upper Midwest is likely to have below normal rainfall. Hawaii and Alaska are both likely to have above normal rain during this period.

What this means

The five categories the Drought Monitor draws, and how the map is made.

D0 Abnormally dry
Going into or coming out of drought.
D1 Moderate drought
Some damage to crops and pastures; water shortages developing.
D2 Severe drought
Crop or pasture losses likely; water restrictions imposed.
D3 Extreme drought
Major crop and pasture losses; widespread water shortages.
D4 Exceptional drought
Exceptional and widespread losses; water emergencies.

The US Drought Monitor is drawn every week by authors at the National Drought Mitigation Center, USDA and NOAA, who weigh rainfall, soil moisture, streamflow, groundwater, vegetation health and reports from local observers. Each map shows conditions through Tuesday morning and is released on Thursday. It shows where drought is and how bad it is; it does not forecast it. CPC's outlooks do that.
