The flooding is a result of a combination of factors:

- Waterways are already high because of a noreaster that dumped water on the northeast

- High Tide is around 3:15 Friday afternoon

- Windy conditions could push water inland

- Additional rain in the area is expected with the system that’s bringing the wind.

D.C. Homeland Security and Emergency Management Director Christopher Rodriguez believes the flooding will be localized to coastal areas.

"We want to make sure that our businesses that are along those coastal areas of our region, in particular our city, make sure you know where your insurance papers are, because flood insurance is going to be really helpful as we recover from this event over the next 48 hours," Rodriguez says.

In D.C, Rodriguez said the Georgetown Harbor, Southeast Waterfront and parts of Navy Yard should prepare.
