Augusta-Richmond and Columbia counties experience a humid subtropical climate with short, mild winters; very hot, humid summers; and a wide temperature variation throughout much of the year. On average, there are more than 200 sunny days a year, though many of them are uncomfortably humid. The monthly daily average temperature ranges from 45 degrees in January to 82 degrees in July. Annually, there are 53 nights with the low reaching the freezing mark, 82 days reaching or exceeding 90 degrees and six days reaching 100 degrees. Snowfall is not nearly as common as in Atlanta, due largely to the area’s elevation, with downtown Augusta being about 900 feet lower than downtown Atlanta. Freezing rain is also a threat in wintertime.
Every second counts in a natural disaster so planning and preparation can be lifesavers. Ready Georgia is a statewide campaign supported by the Georgia Emergency Management Agency/Homeland Security department aimed at motivating Georgians to take action to prepare for a disaster. GEMA/HS coordinates the state’s preparedness, response and recovery efforts to disasters. The program’s website offers online access to tools that will help you plan and be prepared for a disaster, and its mobile app lets you put preparedness tools in the palm of your hand.

The following are considered significant hazards in Georgia.
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 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.

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 http://ready.ga.gov/be-informed/hurricanes for preparedness tips and help in creating a hurricane emergency plan.
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.
For more information, visit the National Weather Service’s website at www.weather.gov/safety/lightning.
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.

Prepare for winter storms by assembling a disaster supply kit for your home and vehicle. Have your car winterized before the winter storm season arrives. Listen to weather forecasts and plan ahead.
When winter storms and blizzards hit, dangers include strong winds, blinding snow and frigid wind chills. Avoid unnecessary travel during storm watches and warnings and stay indoors.
Winter storms can also cause power outages. During a power outage, gather in a central room with an alternative heat source. Use fireplaces, wood stoves and other heaters only if they are properly vented to the outside. Never use an electric generator or a gas or charcoal grill indoors. The fumes are deadly. If you use a space heater, keep the heater away from any object that may catch fire (drapes, furniture or bedding) and never leave it unattended. Avoid letting pipes freeze and rupture by leaving faucets slightly open so they drip continuously.
