This is one of those cases where the rain doesn't correspond to where the eye is, which has the potential to catch people off guard. The eye is north of Taipei already and moving further away but the rain is pounding the south west coast. Some places (pingdong are already over 500 and look to be heading to 1000, which is a castrophic amount of rain.
Meanwhile on the east coast the eye passed not too far to the east of us without bringing any rain - has only really started once the winds changed to the south. Nothing torrential as yet, but looks like it will go all day.
