According to the NWS alert, another advisory came at 5:17 am on Saturday, October 11, which stated that around one foot of water above ground level is expected in some flood-prone areas due to tidal flooding.

Areas affected

The most affected areas are shoreline areas of the City of Alexandria, especially the King Street and Strand Street intersection, where water will be at the curb. Arlington County’s waterfront areas are also under advisement, which means people residing in these areas need to prepare themselves.

Flooding will be mainly during high tide, when tides are expected to be 2-2.5 feet above the normal level. The next high tide at Alexandria will be around 12:11 PM, Saturday, and 12:25 AM, Sunday, according to NWS data.

Weekend weather forecast

Taking weather conditions and alerts into consideration, NWS also provided a weekend forecast for the public to align their upcoming week:

• Saturday: The sky will be mostly cloudy with a high temperature of 71 degrees Fahrenheit. But there are slight chances of showers before 11 AM and again after 3 PM in the daytime.

• Saturday night: The clouds will take over the sky, and it might shower around 5 AM, with lows at around 61 degrees Fahrenheit and northeast winds gusting to 21 mph.

• Sunday: Rains are expected throughout the day with a high of 65 degrees Fahrenheit and northeast winds up to 31mph.

• Sunday night: Sunday might be a little relaxing for the residents. The weather will be mostly cloudy with showers and lows around 57 degrees Fahrenheit.

Safety precautions

Motorists should take extra time for travel and stay alert for temporary road closures, especially near the waterfront.

The advisory remains in effect until 4 am (local time) on Monday, October 13, when tides are expected to gradually recede.
