For the next two weeks, it may be a good idea to have an umbrella with you when heading out in the day.

Singapore may continue to experience thundery showers and gusty winds in the pre-dawn and morning on several days across most of the island due to Sumatra squalls, the Meteorological Service Singapore said on Sep. 1.
