Map of the Southern Water Resources Outlook Region

September 11, 2014 - Rainfall in August was just about average, plus or minus an inch or so, for most of the southern portion of the MARFC service area. Parts of central Maryland, far western Maryland, northern Virginia, and even the central Delmarva Peninsula were 2 to 4 inches above normal rainfall. Temperatures were quite cool running 1 to 3 1/2 degrees below normal. As for September, rainfall has been an inch or less for most areas. The exception is the southern half of the Delmarva Peninsula and southeast Virginia where 2 1/2 to over 8 inches has fallen to date. Temperatures have been warm running 3 to 5 1/2 degrees above normal. Over the past 90 days, many areas have had near average rainfall plus or minus 1 to 2 inches. On the dry side, parts of central and western Virginia are 3 to nearly 5 inches below normal. On the wetter side of things, far western Maryland and southeast Virginia are 3 to 6 inches above normal.

Current (September 11) streamflow data from the U.S. Geological Survey shows that streamflows are normal, though some flows in far western Virginia are below normal. Groundwater levels are near or above normal.

The weather outlook for the next couple of weeks calls for near average rainfall and below average temperatures. The NWS Climate Prediction Center's 30-day outlook for September along with the 90 day outlook for September through November calls for near average precipitation and above average temperatures.

We are at the peak of hurricane season, which has been fairly quiet to date. Tropical weather systems can bring flooding rains to the Mid-Atlantic Region. But for now, no tropical system is threatening the Mid-Atlantic Region.

The outlook for water resources and supplies is good for Maryland, the eastern panhandle of West Virginia, Delaware, and much of Virginia. The outlook is fair for central and western Virginia due to an extended period of dryness. Region-wide, the expectation of near average rainfall should maintain the current status of water resources and supplies over the next couple of weeks.
