Drought conditions are slowly developing in a small portion of the Mid-Atlantic region, especially in central Pennsylvania.

Note: If there are areas in yellow, then these areas are experiencing abnormally dry, but not quite drought, conditions.  See below for additional drought related links.

The outlook for water resources and supplies is good for the Middle Atlantic Region.  However, parts of the region from central Pennsylvania northward are experiencing fair conditions as a result of dry weather over the past month or two. 

 

Rainfall has been sufficient or abundant for eastern and southern parts of the Mid-Atlantic.  This is not the case everywhere, however, especially for central Pennsylvania where a lack of rainfall has become quite noticeable.  The Mid-Atlantic has become wetter in the period from mid-July through mid-August except for, again, central Pennsylvania and points northward.  The overall trend for the next couple of weeks is for overall drier conditions in northern areas but overall wetter conditions for southern areas.  So, those areas that are currently dry are expected to become increasingly dryer.  Water supply and water resources are good for most of the Mid-Atlantic.  The exception is central Pennsylvania northward where conditions are fair.

 

The U.S. Drought Monitor for August 11 indicates that parts of central Pennsylvania are in "Moderate Drought."  This means that irrigation use increases; hay and grain yields are lower than normal; honey production declines; wildfires and ground fires increase; trees and landscaping are stressed; fish are stressed; voluntary water conservation is requested; and reservoir and lake levels are below normal capacity.
