Heavy rains have the city of Alexandria in preparation mode for flooding in the notoriously flood-prone Old Town section of the city.
High tide on that part of the Potomac is expected at 1 a.m. Saturday, and forecasts call for the river to crest at 4.4 feet.
Yon Lambert, director of the city's Department of Transportation and Environmental Services, says that's high enough to flood the intersection of King and Union streets, something that can happen a few times a year.
Residents lined up in their cars in Old Town to pick up free sandbags in preparation for the storm. The city distributes sandbags to residents when forecasts call for a crest of higher than four feet.
Lambert says additional precautions would be triggered if forecasts called for a crest of five or six feet. But with Hurricane Joaquin expected to turn out to sea, the worst-case scenario of a one-two punch of storms appeared to be minimal.
