• Health Concerns: Prolonged exposure to extreme heat can lead to heat-related illnesses such as heat exhaustion and heat stroke. Residents are advised to stay hydrated, avoid outdoor activities during peak heat, and seek air-conditioned environments.

Hurricanes and Tropical Storms

While Columbia is located inland, it is not immune to the impacts of hurricanes and tropical storms. These storms can bring heavy rainfall, strong winds, and flooding to the region, particularly during the peak of the Atlantic hurricane season (August to October).

Historical Hurricanes

• Hurricane Hugo (1989): One of the most significant hurricanes to impact Columbia was Hurricane Hugo, which made landfall in South Carolina as a Category 4 storm. While the eye of the hurricane passed well to the east of Columbia, the city still experienced strong winds and heavy rain, leading to widespread power outages and tree damage.
• Hurricane Florence (2018): More recently, Hurricane Florence brought significant rainfall to Columbia, leading to localized flooding and road closures.

Flooding

Flooding is a concern in Columbia, particularly in low-lying areas and along rivers such as the Congaree. Heavy rainfall from thunderstorms or tropical systems can lead to flash flooding, while prolonged periods of rain can cause rivers to overflow their banks.

Flood-Prone Areas

• Congaree River: The Congaree River, which runs through Columbia, is prone to flooding during periods of heavy rain. Areas near the river, including the popular Riverfront Park, can be affected by rising waters.
• Flash Flooding: Flash flooding can occur in any part of the city, particularly in areas with poor drainage. Urban areas with a lot of pavement are particularly susceptible, as rainwater cannot easily absorb into the ground.

Tornadoes

Tornadoes are relatively rare in Columbia, but they do occur, particularly during the spring and fall. Tornadoes in this region are typically weak (EF0 to EF2), but stronger tornadoes have been recorded.

Tornado Preparedness

• Warning Systems: Columbia is equipped with tornado warning systems, including sirens and emergency alerts, to notify residents of an impending tornado.
• Safety Measures: During a tornado warning, residents are advised to seek shelter in a small, windowless room on the lowest level of their home, such as a basement or interior bathroom.
