According to the weather forecast,
the rainy season has begun
in the south district of Kyushu since yesterday.

I remember that the rainy season of last yeaｒ was
pretty later than that of this year.

I live in the north of Kyushu.
It was raining a little yesterday and it is cloudy today.

Since when will the rainy season in the north district of Kyushu set in ？
