Flood in Allegany County, Maryland

The Town Creek near Oldtown stream gauge reached minor flood stage with peak crest of 14.68 feet. At 14 feet, water overflows the banks just downstream of the Pack Horse Road Bridge.

A slow moving closed upper level low originating from the Gulf of America brought anomalous moisture into the area. A long duration period of rain ensued, with rain rates exceeding two inches an hour during the afternoon of May 13th. The slow moving storms coupled with training led to localized rainfall totals of four to eight inches across western Maryland, with lesser amounts of two to four inches across central Maryland. Most of this rain fell in a 6 hour period, resulting in flash flooding especially across western Maryland.
