What happened
The episode as NWS LWX wrote it up.
Rainfall from two land falling hurricanes made a tremendous impact on the drought that plagued the region since the summer of 1998. Most of the rain from these systems fell east of Frederick with the highest amounts near the Chesapeake Bay. The water shortage came to an end by mid month in all but Allegany and Washington Counties. By the 30th, conditions in Western Maryland were upgraded from an extreme to moderate drought, and were near normal or slightly wet elsewhere. Baltimore/Washington International Airport (BWI) reported a monthly rainfall total of 11.50 inches, 8.09 inches above normal. It was the 2nd wettest September on record. The Maryland Science Center in downtown Baltimore reported a total of 10.83 inches. Other September rainfall totals included Anne Arundel County at 12.5 inches, Prince Georges County at 11.5 inches, St. Mary's County at 11.2 inches, Montgomery County at 10.9 inches, Carroll County at 10.1 inches, Charles County at 10.0 inches, Howard County at 9.9 inches, Frederick County at 8.7 inches, Washington County at 8.4 inches, and Allegany County at 4.1 inches. The much needed rainfall affected rivers and water reservoirs dramatically. Carroll County reported a 2.5 foot jump in the groundwater level during September. The governor of Maryland lifted mandatory water restrictions statewide during the first week of the month. The ban on open burning was lifted for all but Western Maryland as well. However, effects of the drought still lingered in the agricultural community. The drought cost Maryland farmers over $75 million. Across the state by the end of the month, 41% of corn, 17% of soybeans, 13% of sorghum, and 14% of pasture land were still in poor or very poor condition. Farmers reported 33% of subsoil moisture and 11% of topsoil was still short or very short of moisture. The average pumpkin in the fall harvest was on average 3 to 5 pounds smaller than normal. Also, the city of Baltimore reported loosing 300 street trees to the drought, and Howard County reported the loss of 165 trees.
