The video captures a dramatic scene of a large, towering cumulonimbus cloud against a deep blue sky. The cloud is dense and fluffy, with its top spreading out like an anvil, indicating it might be a thunderhead. Smaller clouds are scattered around, and the background features a range of mountains, some of which are partially covered by the cloud's shadow. The overall atmosphere suggests the potential for a storm or heavy rainfall.
A large, white cumulus cloud is seen expanding and growing in size against a deep blue sky. The cloud continues to expand, becoming more voluminous and towering as it moves slightly to the right. The background consists of a range of green mountains, partially obscured by the cloud's growth. The cloud's expansion is gradual but noticeable, with its base becoming more defined and its top reaching higher into the sky.
