With cold weather arriving early this season, Winter Weather Preparedness Week could not
have come at better time. Take a brief moment each day this week to learn about how winter weather could impact Chatham County and what you can do to prepare! Information
and preparedness tips will be shared on our social media pages @ChathamEMA (Facebook, Twitter, and Instagram) and on the CEMA Website.
To kick off this week of preparedness, we encourage residents to gain familiarity with the types of winter precipitation that could impact Chatham County.
Precipitation that forms as a collection of ice crystals when temperatures are at
or below 32°. Snow can make roads slick and impact visibility. Motorists should avoid
driving and if they have to drive, slowdown and use extreme caution.

Precipitation that results from melted snow in the atmosphere that refreezes into
ice pellets before reaching the surface. Sleet may form even when temperatures are
above 32°. Sleet can make roads very slick. Motorists should only drive when necessary
and slow down if there is sleet.

Precipitation that falls as rain but freezes upon contact with the surface.
This happens when air is above 32°, but the ground is at or below 32°. Freezing rain is extremely dangerous for motorists as visibly wet roads may turn to ice with little to no
change in appearance. If there are reports of freezing rain in your area, stay off the roads
and only drive if necessary.

The tiny droplets in fog may freeze if surface temperatures are at or
below 32°. Freezing fog can cause black ice (which is very difficult to see) to form
on roadways, sidewalks, and steps.

Liquid precipitation that is not frozen. Use regular driving precautions during a
rain event and remember that flooded roadways are dangerous. If there is water over
a road you should always #TurnAroundDontDrown

Essentially, fog is a cloud at ground level. Fog can vary in density from light fog
to heavy fog with close to zero visibility.
