Flooding associated with severe storms and heavy rain is one of the most common hazards in the Lowcountry. Due to low-lying topography, flooding along the coast is worsened during high tide. You are likely to see moving water across roadways during flash floods and regional floods. If you encounter water over a road, Turn Around, Don't Drown. Do not enter as you will not know the depth of the water nor will you know the condition of the road under the water.
