Events for October 2017...


October 8th...
As Tropical Storm Nate moved northwest of South Carolina it
spawned a few tornadoes across South Carolina and North Carolina.
An EF-1 tornado touched down near the town of Chappells.

The tornado touched intermittently as it moved north-northeast
for just over 2.4 miles. It initially touched down on the
northern bank of Lake Greenwood on Pineland Road near Fawn Court
and continued north-northeast to Workman Kelly Road. Numerous
large hardwood and softwood trees were snapped at their trunks on
both roads. The tornado continued north-northeast to the
intersection of Highway 39 and Salter Road. This is where the
tornado damaged the roof of a home and severely damaged the roof
and building of a workshop. Much of the metal roofing was
destroyed then blown across the property. The two garage doors of
the building were blown inward. A wood framed work shed with a
metal roof with significant weight was lifted from it`s based and
landed in the nearby wood. A portion of the front porch of the
home was lifted and landing in the back yard. A large work
trailer was overturned in the back yard and damage done to a few
trees around the house. Along Poplar Spring Road, several trees
were snapped at their trunks as the tornado continued northward.
The tornado lifted before reaching Vaughnville Church Road
approximately 2.4 miles after initially touching down. The tornado
lasted approximately 7 minutes.


October 23rd...

An approaching cold front produce a few isolated to severe
thunderstorms. The storms downed trees in Orangeburg county along
Cannon Bridge Road.


October 29th-30th...
As Tropical Storm Phillipe moved up along the east coast it merged
with an area of low pressure across the Mid Atlantic region. This
system deepened rapidly producing a strong pressure gradient
across the region. Behind this system much colder air filtered
southward across the Carolinas on the morning of October 30th.
Many areas saw the first frost and/or freezing temperatures that
morning.
