After drenching the Mid Atlantic region for most of the week, the remnants of Tropical Storm Lee have finally let up their relentlessly rainy reign. Although some flash flood warnings and watches as well as river flood warnings remain in effect, the heaviest rainfall has ended, leaving behind some record-breaking accumulations. Double-digit storm totals have been recorded across at least 10 states from Louisiana to New York. The highest amount appears to be 20.96" at a cooperative station near Colonial Beach, VA, but a plume of very heavy rainfall extended northward through the Susquehanna River watershed of Pennsylvania and New York.

In the immediate Washington/Baltimore area, official storm total rainfall reports include:
Washington National  6.47 
Washington Dulles 6.44
Ft. Belvoir 13.48
Baltimore BWI 8.11
Baltimore Downtown 6.90
Andrews AFB 9.06
