The National Weather Service has extended a coastal flood advisory for the District of Columbia, warning residents and commuters about potential high-tide flooding lasting until this evening. Up to one foot of inundation above ground level is expected in low-lying areas due to tidal flooding, affecting the shoreline in the District of Columbia.
According to the National Weather Service, the advisory is now in effect "until 10 PM EDT this evening," especially around the time of high tide. The forecast suggests a mostly sunny day with temperatures climbing near 70 degrees, although calm winds in the morning are expected to pick up, becoming south 5 to 8 mph in the afternoon.
Areas prone to the effects of high tide, including the seawall adjacent to Ohio Drive, the Hains Point Loop Road, and near the Tidal Basin and Jefferson Memorial, are anticipated to experience shoreline inundation. The next high tide at Washington Channel is pegged for 8:15 AM and again at 8:49 PM, and officials urge caution. "If travel is required, allow extra time as some roads may be closed. Do not drive around barricades or through water of unknown depth," the advisory warns. "Take the necessary actions to protect flood-prone property."
Later in the week, the weather is expected to take a turn with the NWS forecasting a "slight chance of rain after 3 pm" on Tuesday, and a higher likelihood for rain through the evening and following days, including chances of thunderstorms Thursday night. The outlook for the weekend improves with predictions for sunny skies and breezy conditions by Saturday. Precautions remain advised as the coastal flood advisory maintains, "Shoreline inundation is expected along portions of the seawall adjacent to Ohio Drive and the Hains Point Loop Road, and near the Tidal Basin and Jefferson Memorial," emphasizing the potential impact of tidal waters one to one and a half feet above normal.
