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 Division of Homeland Security. 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.

The following are considered significant hazards in North Carolina.
For the Atlantic coast, hurricane season runs from the beginning of June to the end of November. North Carolina is certainly no stranger to hurricanes and has historically taken the brunt of many storms’ landfall. Hurricane storm surge is the biggest threat to life and property, but heavy rainfall, high winds, tornadoes and inland flooding typically accompany these storms. Make a hurricane plan in advance and make sure everyone in the household knows what it is. Be prepared. Once a powerful storm hits, it’s too late to get ready. If you live in a mobile home, a high-rise, on the coast or a floodplain, near a river or inland waterway, or if local authorities order you to evacuate, do so without delay.

Craven County’s proximity to the Atlantic coast makes it prone to flooding and flash flooding. Even small amounts of sea level rise make rare floods more common by adding to tides and storm surge. Area terrain can be poorly absorbent, and dry channels, ditches and lake beds fill quickly. This can lead to flash floods.
A flash flood watch is issued when flash flooding is expected to occur within six hours after heavy rains have ended. A flash flood warning is issued for life- and property-threatening flooding that will occur within six hours. During a flash flood watch or warning, stay tuned to local radio or TV stations or a National Oceanographic and Atmospheric Administration Weather Radio for further weather information.
If you are outdoors during a rainstorm, seek higher ground. Avoid walking through floodwaters — even water 6 inches deep can sweep you off your feet. If you are driving, avoid flooded areas. The majority of deaths in flash 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.
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 suppression. Overexposure also causes wrinkling and premature aging of the skin.
Cloud cover reduces UV levels, but not completely. Depending on the thickness of the cloud cover, you can still burn on a cold and dim day so be prepared with sunglasses, sunscreen, long-sleeved garments, wide-brimmed hats and a parasol.
While more likely at certain times of year, thunderstorms can happen anytime. A severe thunderstorm can knock out power, bring high winds, lightning, flash floods and hail, and turn into a twister in seconds. Pay attention to storm warnings. Remember the rule: “When thunder roars, head indoors.” Once inside, avoid electrical appliances and plumbing fixtures, and use only a cordless telephone in an emergency. Unplug your desktop computer. Do the same with other plugged-in electronics or use surge protectors. The National Weather Service recommends following the 30/30 Rule: People should seek shelter if the “Flash-to-Bang” delay — 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.
Hailstorms are a potentially damaging formation of severe thunderstorms. Hail is created when strong rising currents of air within the storm, called updrafts, carry water droplets to a height where they freeze. Ice particles will continue to grow in size, eventually becoming too heavy to be supported by the updraft, and fall to the ground. Hail is larger than sleet and will only form inside a thunderstorm. The size of the hail stones are a direct function of the size and severity of the storm.
