Another mei yu front passed over the island on May 26-27 but failed to produce any significant rainfall in Taidong (100ml in central mountains of Taiwan)despite 80% pop predictions. This may have been affected by a typhoon away to the east and heading north. Could be that it had a draining effect on the mei yu front, whereas a low pressure system to the south tends to feed moisture into the mei yu through their outlet stream. Another front predicted for Thurs - this could be interesting coz it is expected to wrap around the south east coast - also a cyclone system building to the south east. if that stays low, then you would expect large rainfall totals on the east coast. And there would be need to be to get anywhere near the average of 156ml for May. We are currently sitting on about 60ml with just a few days left.
