Just a couple of days ago the number of users increase and the windice rain was deactivated. I don't know what's the main reason about it, but I guess it is because of the rain catchers. Now that there's no more rain, the chatroom is now back to normal

the rain was not deactivated , it is random and depends on many factors
pretty sure it happened that day , just was not as heavy and was far in between , but if you check the site today , for example
the rains are plentiful and bountiful and happen often

the number of users grew because of the agressive promo campaigns run by Windice
and it doesn't mean that rains depend on the number of the users in chat - its probably the opposite , haha
number of users in chat depend heavily on the freebies and bonuses they get for chatting
I can say that at the moment Windice's chat rains are one of the most generous around
try it out if you haven't already
