October 13, 2013 - A major storm brought drenching rains to much of the southern half of the MARFC service area. 2 to 8 inches of rain have been common so far in October with a few spots getting over 10 inches of rain. In far western areas of Maryland and the eastern panhandle of West Virginia, along with central and western Virginia, generally an inch or two of rain has fallen which is fairly close to average. Over the past 90 days, most areas are running about average for rainfall plus or minus an inch or two. Only central and western Virginia are running 2 to 4 inches below average rainfall. Recent heavy rainfall has wiped out or significantly decreased recent precipitation deficits.

Current (October 13) streamflow data from the U.S. Geological Survey shows that streamflows are much above normal in Delaware, Maryland, far eastern sections of the eastern panhandle of west Virginia, and northern Virginia. Elsewhere, flows are near or above normal. Groundwater levels are generally near normal.

The weather outlook through late October calls for near normal precipitation and temperatures. The NWS Climate Prediction Center's 30-day outlook for October calls for near average precipitation and above average temperatures. The 90 day outlook for October through December calls for near average precipitation and temperatures.

The outlook for water resources across the southern half of the MARFC service area is very good except for central and western Virginia. Here, rainfall has not been abundant in the past couple of months and the outlook is good. This is a change in status for Maryland where improvement is noted and for Virginia where a decrease in status is noted. Recent heavy rain has considerably eased the concern for dryness except for some areas of Virginia. Further, as we move deeper into autumn and the strength of the sun continues to lessen, dryness concerns lessen. As a whole, water resources and supplies are sufficient or abundant.

End.
