September 9, 2013 - Most areas in the southern portion of the MARFC service area have not yet had much rainfall for the month of September. Over the past 90 days, central Maryland, parts of northern Virginia, and parts of the eastern panhandle of West Virginia have seen near normal rainfall. Elsewhere, rainfall has been 4 to 8 inches above normal. For the year to date, most of Virginia along with the northern and central Delmarva Peninsula are 4 to 13 inches above normal precipitation. Elsewhere, precipitation is close to average.

Current (September 9) streamflow data from the U.S. Geological Survey shows that streamflows are near normal except for the region from the District of Columbia to Baltimore. Here, flows are below normal. Groundwater levels are generally near or above normal.

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

Hurricane season is in its' most active period and tropical systems can bring significant rainfall to the Mid-Atlantic Region. Though there are some systems in the Atlantic Ocean basin, rain from a tropical system is not expected in the near term.

The outlook for water resources across the southern half of the MARFC service area is very good. However, a growing area in Maryland, especially from DC to Baltimore, has not had abundant rainfall in the past couple of months. Should this trend continue, which is likely based on the weather outlook, then this region is likely to be downgraded. Overall, water resources and supplies are sufficient to abundant.

End.
