Onshore winds and low-pressure systems off the coast often aggravate flooding by pushing water against the shore and allowing successive tides to build up. At these times, flooding can affect many sections of downtown, as well as stretches of the railway to the Port of Savannah.

When water floods this and other roads, residents often contend with standing water, and downtown parking lots become inaccessible.
