Active AlertsSwitzerland, SC

Areas of fog will continue to develop across much of the South Carolina Lowcountry and Southeast Georgia through 3 AM. The fog could become locally dense at times with visibility dropping to 1/4 mile or less. The nature of the fog is such that visibilities will vary greatly over short distances with the risk for locally dense fog being the greatest near bodies of water and other low- lying areas such as marshes, swamps and large ditches. Motorists should remain alert for these conditions this morning. It is possible more widespread dense fog could develop prior to daybreak and a Dense Fog Advisory may be issued.

If driving, slow down and leave extra distance ahead of you in case a sudden stop is needed.
