The GetWeather.js file contains logic issues in the weather ID mapping, where any unmatched weather condition defaults to WINDY, potentially leading to incorrect weather representation for NFTs.
In GetWeather.js, the code uses a default fallback to WINDY (enum value 4) for any unmatched weather condition:
This is a known issue mentioned in the project documentation, but it could lead to incorrect weather representation for NFTs when the actual weather condition doesn't match any of the explicitly handled cases.

This PoC demonstrates how various weather conditions that don't fit into the explicitly handled cases are all defaulted to WINDY (enum value 4), which can lead to misleading or incorrect weather representation in the NFTs. For example:
Expand the weather condition mapping to cover more cases and provide more accurate representations:
Consider adding more weather states to the enum to better represent the full range of possible weather conditions.
