Motorist slow before entering a dense fog area on Texas 73 near the BASF plant in Port Arthur on Tuesday, Jan. 16, 2007. Lower temperatures and high humidity have caused additional moisture to condense onto the steam released by the plant. The condensation makes the fog more opaque. A north wind has blown the fog over the road and resulted in some accidents in the area. Port Arthur police are warning motorists about the driving condition.
