Drought Early Warning Update for the

Earth Day Edition: Drought Conditions Improve in the Northeast DEWS
Key Points

  • Since the March 22 update, Severe Drought (D2) areas have improved to Moderate Drought (D1) in northwestern Maine.
  • Abnormally Dry conditions (D0) were reduced in areal coverage in parts of Maine, Vermont, and northern New Hampshire and eliminated in southeast New York.

Monitoring the Potential for Evapotranspiration Through the Summer Months
Figure 2: Average daily potential evapotranspiration (ET) increases rapidly at stations across the Northeast in May and June as indicated by the steep slope of the accumulated ET curves. During May and June these stations see between 7 and 8 inches of ET compared to only 3-4 inches in March and April. With the increased ET, a given amount of rainfall is less effective at replenishing soil moisture and surface reservoirs.
The rest of this drought update, including current conditions, outlooks, and impacts, is available online.
This Drought Early Warning Update is issued in partnership between the National Oceanic and Atmospheric Administration (NOAA), U.S. Geological Survey, and the U.S. Department of Agriculture (USDA) to communicate concern for drought expansion and intensification within the Northeast U.S. based on recent conditions and the forecasts and outlooks. NIDIS and its partners will issue future Drought Early Warning Updates as conditions evolve.

This covers the following states in the Northeast U.S.: Maine, New Hampshire, Vermont, Massachusetts, Connecticut, Rhode Island, and New York.
