It is unusual to see a review of a disaster event 50 years later, but that is what this one does. See: FEMA reflects on Hurricane Agnes 50 years later.

With the 50th Anniversary of Hurricane Agnes, one of the worst storms to ever hit the United States, the Federal Emergency Management Agency and the U.S. Army Corps of Engineers are holding special events to recall that storm and encourage residents to learn more about their flood risk and take actions now to be prepared as we enter hurricane season in the Mid-Atlantic region.Hurricane Agnes formed in the Gulf of Mexico and made landfall June 19 as a Category 1 storm and caused significant and widespread damage from Florida to Virginia. before it joined with another storm system before moved into the Atlantic Ocean and back over the Mid-Atlantic region where it dumped immense amounts of rain in the following days and brought flooding to communities like Pottstown and Norristown along the Schuylkill River.According to FEMA, rainfall from Agnes caused catastrophic inland flooding, the geographic scale of which had not been seen in decades. Tragically, 128 people lost their lives across eight states, including 50 in Pennsylvania, 21 in Maryland, 14 in Virginia, and one in Delaware. Across the eastern United States, more than 362,000 people were forced to evacuate their homes due to the flooding, including 222,000 in Pennsylvania alone.
