A few dry and warm days can still be expected
Singapore, 1 September 2016 – The region continues to experience Southwest Monsoon conditions. In the first fortnight of September 2016, the low level winds are forecast to blow predominantly from the southeast or southwest, and are expected to blow from the west on a few days.
2 Over the next two weeks, Singapore can expect five to seven days of short-duration thundery showers mostly in the late morning and afternoon due to strong solar heating of land areas coupled with wind convergence. In addition, thundery showers with occasional gusty winds can be expected on one or two days between the predawn hours and morning due to squall lines moving eastwards from the Strait of Malacca. The rainfall for the first fortnight of September 2016 is likely to be slightly above normal.
3 During the outlook period, dry and warm weather conditions can still be expected on a few days where the daily maximum temperatures could reach around 34°C. On most days, the daily maximum temperatures are forecast to range between 32°C and 33°C.
