The Impact of Hurricane Joaquin (2015)
Hurricane Joaquin, though its center remained offshore, caused immense rainfall and flooding across South Carolina due to its interaction with a strong low-pressure system and an abundant moisture supply. This combination led to a "1,000-year rain event" in some areas. The resulting floods affected numerous counties, leading to:
- Widespread road closures, including major interstates.
- Damage to homes and businesses.
- Significant agricultural losses.
- Disruption of daily life for residents across the state.
The 2015 flood highlighted the vulnerability of the state's infrastructure to extreme rainfall events and spurred discussions on improving flood resilience and warning systems.
