Is there a well that can forecast the weather?

There is a square ancient stone well with a length of 1.5m and a depth of 2m in Hechi Village, Zhu Shi Town, Dongkou County, Hunan Province. For hundreds of years, people have been drinking well water, and there is nothing unusual. In recent years, this well is a bit abnormal. Every day before the rainstorm, the well water turns brown and bitter, but it will return to its original state after three to five hours. Every time it is accurate, it is called "magic weather forecast well" by locals.
