Why is it important for pilots to know the meanings of codes like "+TSRA" in reports?

Understanding weather codes such as "+TSRA" is crucial for ensuring safety during flight operations. This specific code indicates heavy thunderstorm rain, which can pose significant risks to flight safety, including turbulence, low visibility, and lightning strikes. By being knowledgeable about such codes, pilots can make informed decisions regarding flight paths, altitude adjustments, and potential diversions to avoid hazardous weather conditions. This proactive approach helps mitigate risks associated with adverse weather, thereby promoting safer flying environments for both the pilot and any passengers.

While the other choices might seem relevant in a broader operational context, they do not specifically address the immediate and critical importance of interpreting weather conditions effectively to maintain safety in flight operations.
