Charleston is facing an intense heat dome, a phenomenon characterized by prolonged periods of extreme heat. Residents are advised to take proactive measures to ensure the safety and well-being of their households, including pets, vehicles, and outdoor spaces.

### Cooling and Home Maintenance

With temperatures expected to remain high, checking indoor cooling systems is paramount. Ensure air conditioners are functioning correctly and consider scheduling maintenance if any issues are noted. For attics, which can become significantly hotter than ambient temperatures, ensuring proper ventilation can help mitigate heat buildup. This not only improves comfort but can also protect the structural integrity of the roof and attic space.

### Protecting Pets

Pets are particularly vulnerable to heat-related illnesses. Owners should provide ample fresh, cool water and ensure their animals have access to shaded areas, both indoors and outdoors. Avoid strenuous exercise during the hottest parts of the day. For pets that spend time in vehicles, it is critical to remember that car interiors can reach dangerous temperatures within minutes, even with windows cracked. Never leave a pet unattended in a vehicle.

### Outdoor Chores and Vehicle Safety

Outdoor activities and chores should be rescheduled to the cooler hours of the early morning or late evening. This includes tasks such as gardening, lawn maintenance, or any physical labor. When driving, be aware that vehicle components like seatbelt buckles and steering wheels can become extremely hot to the touch, posing a burn risk. Always check surfaces before allowing children or pets to come into contact with them.

### Backup Plans for Vulnerable Residents

It is essential to have backup plans for individuals who may be more susceptible to the effects of extreme heat. This includes the elderly, very young children, and those with chronic medical conditions. Neighbors and community members can play a role by checking on one another, especially those who live alone or have limited mobility. Establishing a communication plan for checking in during periods of extreme heat can be a vital step.

### Why it matters in Charleston

The persistent heat poses unique challenges for Charleston, a city known for its historic architecture and outdoor lifestyle. The Medical University of South Carolina (MUSC) often sees an increase in heat-related emergencies during such periods, highlighting the strain on local healthcare resources. Ensuring that homes, particularly older structures in neighborhoods like South of Broad, have adequate cooling is not just about comfort but also about preventing health crises. Furthermore, the city’s numerous parks, such as Marion Square and Waterfront Park, become less accessible for recreation, impacting the daily routines of many residents. Planning for these extreme weather events is crucial for the resilience of the Charleston community.
