Which code indicates a weather condition with heavy rain associated with thunderstorms?

The code +TSRAGR indicates a weather condition characterized by heavy rain associated with thunderstorms. The prefix '+' signifies heavy intensity, while 'TS' represents thunderstorms, and 'RA' is the abbreviation for rain. The inclusion of 'GR' at the end of the code denotes the presence of hail, which often accompanies thunderstorms.

In the context of aviation weather reporting, understanding these codes is crucial for interpreting real-time conditions that may affect flight safety. The specific use of this combination makes it clear that the weather involves not just rain, but heavy rain that is associated with thunderstorms, making it a serious consideration for pilots and meteorologists alike.

Other codes provided refer to different weather phenomena. For instance, -FZRASN indicates light freezing rain and snow, which affects conditions differently than heavy rain and thunderstorms. DRSN refers to drizzle and snow, while BCFG signifies fog, none of which correlate to heavy rain and thunderstorms. These distinctions underscore the importance of specific weather codes in accurately assessing and communicating weather conditions.
