What is indicated by the weather code TSRAGS?

The weather code TSRAGS indicates a combination of weather phenomena associated with thunderstorms. In this case, it specifies that a thunderstorm is occurring, accompanied by moderate rain and small hail. The presence of "TS" at the beginning of the code clearly identifies it as a thunderstorm. Following this, "RA" signifies rain, which is described as moderate in this context, while "GS" denotes small hail.

This combination of elements is an important detail for aviation, as it helps pilots and meteorologists assess the potential hazards associated with the thunderstorm. Understanding these codes allows for better preparation and response to varying weather conditions.

The other choices highlight different weather scenarios that are not represented by this specific code. For instance, heavy snowfall and dense fog do not relate to thunderstorms or rain and hail, which further confirms why those options do not fit with the code TSRAGS.
