Update: [1]Several hundered people trapped in Eastern Cape due to heavy snowfall [2] How do one survive in heavy snowfall and cold weather?

Earlier report: The SAWDIS have just learned that several hundred people are currently trapped in the Eastern Cape due to heavy snowfall.  Some people are cut-off from the outside world.  Several towns are without power due to falling power lines.  It is still snowing in many parts of the Eastern Cape, Kwazulu Natal and North Eastern Free State.

SABC News reports:  "More than one hundred people who are trapped in the north of the Eastern Cape are urging the government to rescue them with helicopters."

SAWDIS:   People that are currently trapped in the Eastern Cape and Kwazulu Natal areas as a result of heavy snowfall urged the government to rescue them with helicopters.  Although this would be possible in normal weather conditions one should bear in mind that this is a severe weather event.  Visibility, low clouds, rain, snow and strong wind makes it virtually impossible for helicopters to fly.  Weather plays a very important roll in a successful rescue mission and is it virtually impossible to fly in adverse weather conditions currently experienced in many parts of the country.

How do one survive in heavy snowfall and cold weather?

Knowing how to survive a blizzard or other winter storm is a crucial, bit of knowledge everyone should know. There are multiple types of winter storms and each can be deadly killers.  Imagine being snowed into your house or being stranded in a car during severe snowfall.  Would you know how to survive? Here, this advice could save you life.

Outside

  • Seek some form of shelter immediately. Blowing winds can cause the wind chill to reduce your core body temperature to dangerous levels. The risk of frostbite and hypothermia increase every minute you are exposed to the cold weather.
  • If you are wet, try to get dry. Lighting a small fire will not only provide warmth, but will enable your clothing to dry out.
  • Deep snow can actually act as an insulation from the wind and cold temperatures. Digging a snow cave can actually save your life.
  • Stay hydrated, but do not eat snow. You need to melt snow before eating it. Your body must still heat the ice and melt it. Instead, gather snow in some sort of vesicle and attach it to your body for a slow melting process. A canteen inside your coat, but not directly next to the skin will speed the melting process.
In a car, truck or bus

  • Never leave the vehicle. If you are stranded, the vehicle offers a form of protection from overexposure to the cold. A single person walking through the snow is also harder to find than a stranded car or truck.
  • It is okay to run the car for short periods to provide some heat. Remember to crack the windows a small amount to allow for the circulation of fresh air. Dangerous exhaust fumes, including carbon monoxide, can build up very quickly. This is especially true if the tailpipe is buried in the snow.
  • Keep yourself moving. A car offers little room for you to keep your blood flowing, but exercise is a must. Clap your hands, stomp your feet, and move around as much as possible at least once an hour. In addition to keeping your body moving, keep your mind and spirit from wandering too far into gloom. While potentially dangerous situations are not a time of joy, keeping yourself from added stress will allow you to make smarter decisions when necessitated.
  • Make the car visible for a rescue. Hang bits of bright colored cloth or plastic from the windows. If the snow has stopped falling, open the hood of the car as a signal of distress.
At home
  • If the electricity goes out, use an alternative form of heat with caution. Fireplaces and kerosene heaters can be dangerous without proper ventilation. Keep children away from any alternative heat source.
  • Stick to one room for heat and close off unnecessary rooms in the house.
  • Make sure there are no air leaks in the room. Keep sunlight streaming through the windows in the day, but block all windows at night.
  • Keep hydrated and nourished in case the heat is out for an extended period. An unhealthy body will be more susceptible to the cold than a healthy one.
  • Pets must also be protected from the cold. When temperatures drop below freezing, outdoor pets should be moved indoors or to a sheltered area to protect them from the cold.
Always have a winter weather emergency plan available. Ideally, you should create an emergency plan for your home and your car. If you have small children, remember to actually practice using the plan In the event of a winter emergency, kids should know the plan and what to do.

In addition to having a winter safety plan all family members should be able to recognize the signs of hypothermia and basic first aid treatment for cold exposure.

Finally, if your region is prone to winter storms of any type, you are encouraged to monitor the SA Weather and Disaster Information web-site and SAWDIS Twitter pages for weather warnings and observations of severe weather in the event of an emergency. Multiple types of winter weather advisories are issued and each have their own dangers.  The SAWDIS is currently your only early warning web-site in South Africa.
