It took a while, but May 20, we finally got a solid, soaking mei yu. 'Stationary' cold front, which has actually been oscillating over Taiwan - had dipped down south for the last two days, but came back with interest bringing the biggest rain of the year to Taidong. three days ago we got 15ml, then nothing, though overcast skies, then today it started raining steadily around 5 in the morning and hasn't let up since then (10am)- we are up to 15 so far and still going strong. Noticed clouds rushing up from the south yesterday evening and chugging north, which was curious coz there was no ground level wind at the time - thought that might have been a sign of something coming and seems it was.Front is being fed by areas of moisture to the south - two more low pressures to the east of ppe have also formed and these should add to the whole thing in the coming week.
