It's windy and rainy when people are buried after death, okay?

Personally, I think it is a good sign. There are two popular words: "rain hits the coffin, and the champion comes out" and "rain pits, three generations prosper". It shows that it happened to rain when it was buried, which proves that some descendants of the deceased will reach the peak. If it rains when the tomb is closed, the next three generations will prosper. Rain brings wealth, which is a good sign. I hope my answer will satisfy you.
