What is a risk associated with low ceilings and reduced visibility in thunderstorms?

The risk associated with low ceilings and reduced visibility in thunderstorms primarily involves the heightened danger of collision with terrain or other aircraft. When ceilings are low and visibility is limited, pilots struggle to maintain situational awareness. This makes it challenging to visually identify obstacles such as hills, towers, or other aircraft in the vicinity. The lack of visual reference significantly increases the likelihood of flying into these hazards, especially during critical phases of flight like takeoff or landing.

Additionally, thunderstorms can cause sudden and severe weather changes, complicating navigation and further diminishing the pilot's ability to assess their environment. The combination of all these factors leads to a substantially increased risk of accidents in such conditions, underscoring why safety protocols and preparation are crucial when faced with thunderstorms and poor visibility.
