It really rains often in November

There is rain in the forecast for this weekend, and more rain is forecast for sometime next week.
The actual amount of precipitation might not compare to the monsoon season, but
the number of rainy days in the Seoul metropolitan area might be as many as, or perhaps even more than, during the monsoon season.
This is because the central region had relatively few rainy days during this year's monsoon.
It feels like winter will arrive right after the rain stops next week.
