The sinkhole may have been formed after Washington, DC, experienced substantial rainfall last week, although officials haven't disclosed a cause.

"Washington, DC, received measurable rain eight consecutive days through Saturday," said weather.com meteorologist Chris Dolce Tuesday. "The total for that period of time was 6.14 inches, which is more than 2 inches greater than the average rainfall for the entire month."
