What does the abbreviation -TSRA HZ represent?

The abbreviation -TSRA HZ specifically conveys weather conditions involving a thunderstorm with light rain and the presence of haze. In meteorological terms, TSRA indicates a thunderstorm (TS) accompanied by light rain (RA). The prefix "-" denotes the intensity of the rain, indicating 'light.' The inclusion of 'HZ' refers to haze, which is a phenomenon characterized by reduced visibility due to small particles or moisture in the air, creating a veiled atmosphere.

Understanding this combination is vital for pilots and meteorologists, as it provides a clear and concise description of the expected weather conditions that could impact flight operations. It reflects an environment where visibility may be compromised due to both rain and haze, which informs decisions regarding safety and navigation in affected areas.
