What does the term 'Heavy' indicate in the context of weather reporting?

In weather reporting, the term 'Heavy' is used to describe the intensity of precipitation. Specifically, it indicates that a significant amount of precipitation, such as rain or snow, is occurring. This term is important for pilots and operators of unmanned aircraft, as heavy precipitation can affect visibility, aircraft performance, and safety.

The notation '+' is used to indicate heavier rainfall or snowfall, helping meteorologists and aviators quickly assess conditions. This communication of precipitation intensity is crucial for informed decision-making regarding flight operations.

In contrast, other choices would not adequately describe the nature of heavy precipitation. Options like 'Normal' and 'Severe' do not provide a precise measurement of intensity, and '-' typically denotes a lesser amount of precipitation, rather than indicating the strength associated with 'Heavy.' Understanding these distinctions is vital for safe operations in varying weather conditions.
