This is from the monthly forecast on CWB.
b). Oct27~Nov2 : The mean temperature of this week is most likely to be near normal all over Taiwan. The precipitation of this week has the smallest probability of being above normal in north and east parts of Taiwan. While in central and south parts of Taiwan it tends to be no rainfall.

Not very promising. If we get no further rain this month (10 days left)then we will end up with a grand total of 3ml. Given that the mean for Oct in Taidong is 182 ml, that will mean we have only received 1/60th of the average rainfall. That's a serious shortfall and coming on the back of a dry Sep as well. And then we start the dry season! Nov falls away to 80 ml, then it's 40, 30, 40, 40, 65 from Dec-April.
