Alexandria, VA

The weather is expected to make a dramatic turn over the next few hours.

After some early preparation last night by the Alexandria Fire Department and other city agencies, yesterday’s Flood Watch has been upgraded by the National Weather Service to a Flood Warning for Alexandria and surrounding localities.

Today’s bad weather is the result of Isaias, which made landfall in North Carolina last night as a Category 1 hurricane and is moving north. It has since been downgraded to a tropical storm.

A Flood Warning means flooding is imminent or occurring. For those driving, the National Weather Service said to turn around and not to risk flooded roads as most flood deaths occur in vehicles.
