Quick Answer
When clouds begin swirling, survivalists should watch for signs of a storm brewing, such as changes in cloud height, shape, and color. They should look for cumulonimbus clouds with towering vertical growth, an anvil-shaped top, and a flat base. These clouds can indicate a severe thunderstorm or tornado.
Reading the Clouds
When clouds start swirling, it’s essential to identify the type of cloud formation. Cumulus clouds are puffy and white, while stratus clouds are layered and gray. Cumulonimbus clouds, on the other hand, are towering and can reach heights of over 10,000 meters (33,000 feet). These clouds can produce severe thunderstorms, heavy rain, and even tornadoes.
Storm Indicators
Survivalists should look for specific indicators that a storm is brewing. These include a rapid change in wind direction, a sudden drop in temperature, and an increase in cloud height. The presence of a cloud base below 2,000 meters (6,600 feet) can also indicate a severe storm. Additionally, the formation of a lenticular cloud, which is a type of cloud that forms in the lee of a mountain or hill, can indicate a strong wind shear.
Fronts and Clouds
A front is a boundary between two air masses of different temperatures and humidity levels. When a front approaches, clouds will often form in a specific pattern. A cold front will typically produce a line of cumulonimbus clouds, while a warm front will produce a mass of stratus or stratocumulus clouds. Survivalists should be aware of the type of front and the associated cloud patterns to better predict the weather.
