SITUATION OVERVIEW
------------------

Hurricane Michael is forecast to make landfall on the Florida
Panhandle this afternoon. The storm will track northeastward across
Georgia and South Carolina through Thursday as a tropical storm. There
will be a threat of tornadoes and flash flooding. Periods of tropical
storm force wind will occur. The main time period for the most
significant impacts is late tonight and Thursday.

POTENTIAL IMPACTS
-----------------

* TORNADOES:
Protect against a tornado event having possible impacts 
across central South Carolina and east-central Georgia. 
Potential impacts include:
    - A few places may experience tornado damage, along with power 
      and communications disruptions.
    - Locations could realize roofs peeled off buildings, chimneys 
      toppled, mobile homes pushed off foundations or overturned, 
      large tree tops and branches snapped off, shallow-rooted trees 
      knocked over, moving vehicles blown off roads, and small boats 
      pulled from moorings.

* FLOODING RAIN:
Protect against dangerous rainfall flooding having possible 
significant impacts across central South Carolina and east-central Georgia.
Potential impacts include:
    - Heavy rainfall rates may lead to flash flooding along small 
      streams, roadways, and in poor-drainage areas. 

* WIND:
Protect against dangerous wind having possible significant impacts 
across central South Carolina and east-central Georgia. 
Potential impacts in this area 
include:
    - Some minor damage to roofing and siding materials, along with damage 
      to porches, awnings, carports, and sheds. Unsecured lightweight 
      objects become dangerous projectiles.
    - Several large trees snapped or uprooted, but with greater 
      numbers in places where trees are shallow rooted. Several 
      fences and roadway signs blown over.
    - Some roads impassable from large debris, and more within urban 
      or heavily wooded places. 
    - Scattered power and communications outages, but more prevalent 
      in areas with above ground lines.


PRECAUTIONARY/PREPAREDNESS ACTIONS
----------------------------------

* EVACUATIONS:
No major evacuations are expected in central South Carolina or
east-central Georgia at this time.


* OTHER PREPAREDNESS INFORMATION:
A small interior room on the lowest floor usually offers the
best protection from tornadoes. 

Do not attempt to drive on flooded roads. It takes little water to
move a vehicle off the road and into deeper water. Also, the road
bed may not be intact below flood waters.

NEXT UPDATE
-----------

The next local statement will be issued by the National Weather 
Service in Columbia SC around 1130 am, or sooner if conditions 
warrant.
