An ominous storm cloud was recently sighted over Hinesville, Georgia on August 31 st and it looked like an incoming sky tsunami. Neighbourhood citizen and photographer Johanna Hood made some amazing photos and videos of the stunning shelf cloud, which is typically a precursor to a big thunderstorm.

A shelf vapour is a low-key, horizontal, wedge-shaped arcus gloom. A shelf cloud is attached to the base of the mother cloud, that typically a thunderstorm, but could form on any kind of convective clouds. Rising cloud flow often can be seen in the leading( outer) part of the shelf mas, while the underside often emerges turbulent and wind-torn. Cool, sinking breeze from a storm cloud’s downdraft spreads out in all the regions of the region surface, with the edge called a gust breast. This outflow pieces under heated aura being selected into the storm’s updraft. As the lower cool air filches the heated moist air, its sea compress, generate a cloud which are frequently wheels with the differences among gusts above and below( wind shear ).[ source]
