[Grammar] Does this comma mean "and?"

[kadioguy]

Hello, everyone.

In the following sentence:

While wet weather continues in the north, northeast on Monday, temperatures are expected to rise significantly Tuesday, according to the Central Weather Bureau.

(http://www.chinapost.com.tw/taiwan/national/national-news/2017/04/24/496103/Soggy-today.htm)

In "While wet weather continues in the north, northeast on Monday...", does the comma mean "and"?

If not, what does it mean?

Thanks!

PS. If there is any grammatically wrong in my narrative, please correct it. I am grateful for your help.

I suppose it does. However, there should be an "and" between "north" and "northeast."
