DISCUSSION: As the clocks are turned all the way back to June 2nd, 1889, we arrive at a very historic and destructive day in Mid-Atlantic weather history. It was on this early June day back in 1889 that a heavy rainfall event caused substantial flooding within the city of Johnstown, Pennsylvania. By the same token, this heavy rainfall event also put pressure on the dam located in Johnstown, PA. The same storm that caused the historic dam failure in Johnstown, PA, also affected Washington, D.C. The streets and reservations in the center of the city and all the wharves and streets along the riverfront were under water. Pennsylvania Avenue was flooded from 2nd to 10th Streets. It goes without saying that a heavy rainfall event of this magnitude definitely caught many people by surprise at that point in history based on the much more limited forecasting tools available at that time. It is also important to note that the photo attached above is courtesy of the Library of Congress which shows flooding on Pennsylvania Ave.
