DC weather history for August 20

A torrential 1963 downpour set a rainfall record, triggering significant flooding, closing National Airport, and inundating homes and businesses across the region.

On this date in 1963, a calendar-day record 4.83 inches of rain fell. The U.S. Geological Survey reported significant flooding occurred in northeast Alexandria in Virginia near Four Mile Run.

“The flooded area extended about four blocks between Fourmile Run and Glebe Road and inundated about eight blocks containing 19 apartment buildings (about 100 apartments were flooded), 31 business establishments, and eight houses,” it wrote. “Several other areas also suffered inconveniences and damage. Traffic was halted or slowed in many places. National Airport was closed for 3 hours. There were numerous problems, serious to the individuals concerned, such as water in basements and collapse of retaining walls and sidewalks.”

Here are other notables from the day:
