GSWSA and its service area are susceptible to the threat of tornadoes.
According to the South Carolina Emergency Management Division, South
Carolina has averaged 11 tornadoes each year since 1950, resulting in 47
fatalities and over 1,000 injuries. South Carolina ranks twenty-sixth (26 TH )
in the nation for the number of tornado strikes, and eighteenth (18 TH ) in the
number of tornadoes per square mile.
Horry County averages somewhere around 2-3 Tornado Warnings each year.
In addition, there may be another 2-3 Waterspout sightings each year along
our coastline.
The most common period for tornadoes in South Carolina is during the
months of March, April, and May, between 3:00 p.m. and 9:00 p.m.
However, tornadoes can and do occur outside of these time frames.
While most tornadoes occurring in South Carolina, and in Horry County, are
not particularly large or powerful (usually F0 or F1), they can and do result
in damage, injuries, power outages, etc.
