The wet weather has been so persistent that the 318.6mm of rain that fell in Changi from Friday, the first day of this year, was more than the average of 238.3mm for the month of January. SMU Associate Professor of Science, Technology and Society Winston Chow projected that the record for the highest total rainfall in one day for January could be broken on Saturday as well. "With the monsoon surge not expected to cease until Sunday, chances are this record will be broken with time to spare," he said in a tweet on Saturday morning. Assoc Prof Chow explained monsoon surges are typical during this season, and that South-east Asia being in a La Nina phase now might lead to more rainfall than normal.
