Local Hazards

Every second counts in a disaster so planning and preparation can be lifesavers.

Ready North Carolina is the state’s official emergency preparedness campaign managed by the North Carolina Department of Public Safety. The ReadyNC mobile app is an all-in-one tool to help people get ready for everything from traffic jams to hurricanes and ice storms. The app gives information on real-time traffic and weather conditions, river levels, evacuations and power outages. The website provides information on creating an emergency plan and emergency kit, pet preparedness and disaster preparedness for seniors.

Another great resource for natural disaster and severe weather information is the Centers for Disease Control and Prevention website at www.cdc.gov/disasters. Here you can find information on how to prepare for various weather emergencies.

The following are considered significant hazards in North Carolina.

Extreme Heat and Sun Exposure

Some exposure to sunlight is good, even healthy, but too much can be dangerous. Broad-spectrum ultraviolet radiation, listed as a known carcinogen by the National Institute of Environmental Health Science, can cause blistering sunburns as well as long-term problems like skin cancer, cataracts and immune system suppression. Overexposure also causes wrinkling and premature aging of the skin.

Cloud cover reduces UV levels, but not completely. Depending on cloud cover thickness, you can still burn on a chilly, overcast day, so be prepared with sunglasses, sunscreen, long-sleeved garments, wide-brimmed hats and a parasol.

Because of the county’s high temperatures, it is important to take precautions to avoid heat exhaustion and heat stroke. Stay indoors when temperatures are extreme. Drink cool liquids often, particularly water, even if you do not feel thirsty. Avoid alcoholic beverages as they dehydrate the body. Eat small, frequent meals and avoid foods high in protein, as they increase metabolic heat.

If you must venture outdoors, avoid going out during midday hours. Wear lightweight, light-colored clothing to reflect sunlight. Avoid strenuous activities and keep hydrated. Cover all exposed skin with a high SPF sunscreen and follow general sun exposure precautions. Never leave children or pets alone in closed vehicles.

Heat exhaustion symptoms include heavy sweating; weakness; cold, pale and clammy skin; a fast, weak pulse; nausea or vomiting; and fainting. If you experience symptoms of heat exhaustion, you should move to a cooler location. Lie down and loosen your clothing, then apply cool, wet cloths to your body. Sip water. If you have vomited and it continues, seek medical attention. You should seek out immediate medical attention if you experience symptoms of heat stroke, such as a body temperature of more than 103 degrees; hot, red, dry or moist skin; a rapid and strong pulse; or unconsciousness.

Floods

Floods are the most common natural disaster in the United States. Even beyond coastal regions, flash floods, inland flooding and seasonal storms affect every region of the country, damaging homes and businesses. It is dangerous to underestimate the force and power of water.

During a flood watch or warning, gather your emergency supplies and stay tuned to local radio or TV stations for further weather information. If you are outdoors during a rainstorm, seek higher ground. Avoid walking through any floodwaters — even water 6 inches deep can sweep you off your feet. If you are driving, avoid flooded areas. The majority of deaths in floods occur when people drive through flooded areas. Roads concealed by water may not be intact. Water only a foot deep can displace a vehicle. If your vehicle stalls, leave it immediately and seek higher ground. Rapidly rising water can engulf a vehicle and sweep it away.

Hurricanes

Hurricane season begins June 1 and ends Nov. 30. Hurricane hazards come in many forms, including high winds, heavy rain, flooding and storm surges (high tidal waves). Visit https://readync.org/EN/Informed_NatHaz_Hurricane.html for preparedness tips and help in creating a hurricane emergency plan.

Thunderstorms

While more likely at certain times of the year, thunderstorms can happen anytime. A severe thunderstorm can knock out power; bring high winds, lightning, flash floods and hail; and spin into a twister in seconds. Pay attention to storm warnings. Remember the rule: “When thunder roars, head indoors.” The National Weather Service recommends following the 30/30 rule: People should seek shelter if the “flash-to-bang” delay — the length of time in seconds from the sight of the lightning flash to the arrival of its subsequent thunder — is 30 seconds or less, and remain under cover for 30 minutes after the final thunderclap.

Tornadoes

Tornadoes can develop quickly, with minimal warning, so it is important to have a plan in place before they occur. If a tornado watch is issued, weather conditions favor the formation of tornadoes, such as during a severe thunderstorm. A tornado warning is issued when a tornado funnel is sighted or indicated by weather radar. You should take shelter immediately during a tornado warning.
