Event: Coastal Flood Warning
Sender Name: NWS Baltimore MD/Washington DC
Issued: 2018-12-17T16:47:00-05:00
Expires: 2018-12-18T01:00:00-05:00
Description: * LOCATIONS…Shoreline in the District of Columbia.

* TIDAL DEPARTURE…Tidal anomalies themselves will be 1 to 1.5
feet above normal. However, the main source of excess water
will be fresh water flowing down the Potomac from recent heavy
rains, which will overwhelm the tidal anomalies, particularly
at Wisconsin Avenue.

* TIMING…Through midday Tuesday. Flooding is peaking in
severity this afternoon.

* IMPACTS…Inundation will threaten buildings along the immediate
shoreline in Georgetown. Backwater flooding on Rock Creek may
also approach structures. A majority of Roosevelt Island will be
covered by flood waters. The unprotected area on the Southwest
Waterfront at the DC Seafood Market is expected to flood. Water
is expected to approach parts of the Hains Point Loop Road, but
it will likely be closed. Elsewhere, inundation of one to three
feet above ground level can be expected in low-lying,
unprotected areas.

Instruction: A Coastal Flood Warning means that flooding is occurring or
imminent. Coastal residents in the warned area should be alert
for rising water, and take appropriate action to protect life and
property.
