What weather conditions does the code -FZRASN describe?

The code -FZRASN is a specific weather observation code used in aviation meteorology. Each portion of the code provides critical information regarding precipitation types and intensity. The "FZR" portion indicates "freezing rain," while "ASN" stands for "snow." The presence of the minus sign before the FZR indicates that the freezing rain is light in intensity. Therefore, the entire code represents light freezing rain along with snow.

This understanding of weather codes is crucial for pilots and aviation personnel as it provides insights into current weather conditions that could impact flight safety and operations. The combination of light freezing rain and snow can create hazardous conditions, making it important to decode the weather information accurately.
