Special Weather Statement

Special Weather Statement issued March 7 at 3:56AM EST by NWS Charleston SC
Mar 7, 3:56 AM Mar 7, 8:00 AM
Areas of fog will continue to develop across much of the South
Carolina Lowcountry and Southeast Georgia through sunrise. 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.
