    • First two weeks of July to be rainy, but expect a few warm days: Met Service

      SINGAPORE: The first fortnight of July is expected to be rainy, much like the second half of June, the Meteorological Service Singapore (MSS) said on Friday (June 30).

      Thundery showers are expected mostly in the late morning and early afternoon on five to seven days, the Met Service said.

      In addition, widespread thundery showers with occasional gusty winds are expected on two or three mornings during that period.

      The daily temperature is mostly expected to range between 25°C and 33°C.

      However, a few warm days are expected in the latter half of the fortnight, where the daily maximum temperature could reach about 34°C.

      RAIN BROKE WARM, DRY SPELL IN JUNE

      The second half of June saw more rainfall than the first half of the month, with the heaviest rain on Jun 18, the Met Service said. That day, the Mandai area saw the highest daily rainfall, logging 137mm of rain.

      The lowest daily minimum temperature recorded was 21.8°C on Jun 23, a day that saw widespread rain across Singapore.

      Dry and warm weather prevailed in the earlier half of the month, with below-average rainfall.

      About half of Singapore received below-normal rainfall in June, the Met Service said. The Tanjong Katong area received the lowest rainfall of 81.6mm, which was 36 per cent below average.

      Rainfall was highest in the Jurong area, which logged 255mm of rain, 59 per cent above average.

      At the Changi climate station, the mean monthly temperature recorded for June was 28.5°C, which is slightly warmer than the long-term mean of 28.3°C for the month.

    • Dry and warm weather forecast for second half of July

      SINGAPORE: Unlike the first two weeks of July, the weather for the second half of the month is expected to be dry and warm, said the Meteorological Service Singapore (MSS) on Monday (Jul 17).

      The daily maximum temperatures are forecast to be around 32°C, with some days seeing a high of around 34°C.

      Still, there could be short, thundery showers expected mostly in the afternoon for four to six days and widespread thundery showers on one or two days in the early hours of the day, MSS said. 

      Rainfall forecast for the month remains normal, despite the above-average rainfall for the first two weeks of July. Paya Lebar saw the highest rainfall of 168.4mm while the lowest rainfall was recorded in Changi at 77.2mm.

      "The wet weather in the first fortnight of the month was also due to the passage of Sumatra squalls which brought widespread thundery showers with gusty winds to Singapore on some days between the predawn hours and early morning," said MSS.

      During this period, the highest daily rainfall of 110.6mm was recorded in Bukit Timah on Jul 14. 

      Night-time weather during this period was generally cool with daily minimum temperatures dipping to between 22.3°C and 24°C on 10 days. The lowest daily temperature of 22.3°C was recorded in the Marina South area on Jul 12. Additionally, the daily maximum temperatures ranged between 28.7°C and 33.7°C.

    • Wet weather expected to persist in second half of August: Met Service

      SINGAPORE: More rainy days are expected in the second half of August, the Meteorological Service Singapore said in an advisory on Wednesday (Aug 16).

      During this period, short-duration thundery showers are expected on six to eight days, mostly in the late morning and early afternoon, according to the Met Service.

      It added that on one or two days, there could be widespread thundery showers accompanied with gusty winds between pre-dawn hours and the early morning, due to Sumatra squalls.

      Temperatures are likely to be similar to that of the first half of August, with temperatures ranging between 25°C and 33°C on most days. Daily minimum temperatures could go as low as 22°C, especially when rain falls over the island for most of the day, the Met Service added.

      However, a few warm days can be expected in the later part of the month, with the daily maximum temperature reaching as high as 34°C on a few days.

    • Rainy weather expected to continue in September: Met Service

      SINGAPORE: The rainy weather Singapore experienced in the first half of September is expected to continue for the rest of the month, said the Meteorological Service in an advisory on Friday (Sep 15).

      There will be thundery showers - mostly during the late morning and early afternoon - on six to eight days in the coming fortnight, the Met Service said.

      In added that between the pre-dawn hours and morning, widespread thundery showers and gusty winds are expected on two or three days because of the passage of Sumatra squalls.

      The total rainfall for September is expected to be slightly above normal, according to the Met Service.

      The daily temperature on most days is expected to range between 24°C and 33°C. However, the temperature may fall to as low as 23°C on one or two rainy days.

    • Factories, cars behind haze in Singapore

       

      Hazy conditions in parts of Singapore this week might have prompted fears that fires were once again burning in the region, but experts point to culprits closer to home: factories and cars.

      Air quality scientist Erik Velasco told The Straits Times it was not transboundary haze: "The haze-like condition could have been due to the concentration of particle vapour and local emissions - from cars and factories."

      Usually these particles would disperse on their own, but Dr Velasco said that cloudy conditions and "not too much wind" could have caused the vicinity to appear hazy.

      Residents in some areas, including Pasir Ris, had reported hazy conditions on Tuesday even though the 24-hour Pollutant Standards Index (PSI) level was in the moderate range at 6pm that day.

      The hourly concentration readings for PM2.5 - tiny pollutant particles associated with haze - were also in the normal band, said the National Environment Agency (NEA) in a daily haze update.

      In response to queries, NEA said that the "slightly hazy conditions" on Tuesday morning were due to an accumulation of particulate matter under "light wind conditions".

      This was coupled with some convergence of winds around the south-west areas of Singapore. "The accumulation of particulate matter had dispersed around noon and PM2.5 concentration readings have remained in Band I (Normal)."

      Dr Velasco added that rainy conditions meant there might not have been much solar radiation as well. Solar radiation releases heat, which produces turbulence that helps to disperse particles in the air.

      "All these contributed to the concentration of particles and what looked like hazy conditions. People have nothing to worry about."

      NEA said that due to cloud cover, it did not detect any hot spots in Sumatra on Tuesday, but added that there were showers over most parts of the area that day.

      The incident comes after the events of last Monday, which saw a chemical stench cloaking parts of the island, in areas like Sengkang, Punggol and Bishan. Experts had ruled out volcanic action in Bali and the haze as its cause.

      The source of the stench was later traced to a chemical plant in the Johor Baru industrial town of Pasir Gudang.

      The daily haze update for yesterday showed that the 24-hour PSI was in the good-to-low end of the moderate range, and the hourly PM2.5 concentration was in the normal band.

      There were showers over most parts of Sumatra and no hot spots were detected due to cloud cover yesterday.

      A version of this article appeared in the print edition of The Straits Times on October 05, 2017, with the headline 'It's hazy 'due to local emissions''.

    • Wet and thundery weather to continue on Sunday: NEA

      SINGAPORE - Thundery showers will again blanket many areas in the late morning on Sunday, according to NEA.

      The agency also notes on its website that lightning can strike more than 10km away from a thunderstorm cloud.

      The forecast comes on the heels of a wet Saturday (Oct 7) afternoon. What had begun as a cheerful sunny morning was overshadowed after lunch by ominous thunderheads that roared over the island accompanied by flashes of lightning.

      This prompted the National Environment Agency (NEA) to tweet multiple warnings of heavy rain with gusty winds over many parts of Singapore, starting (tweets) around 3pm.

      An animation on NEA's website showed the locations of multicoloured "clouds" - ranging from cyan for light rain through green, yellow, orange, red and pink for very heavy rain - as recorded every five minutes as they moved across the map, leaving hardly any part of the island untouched.

      First to come within a hair's breadth of flooding was Paya Lebar Road, with water levels reported at more than 90 per cent at 3.28pm by an automated tweet from national water agency PUB that additionally warned of "high flood risk".

      Next to get the deluge was Leng Kee Road, where the electronic water-level sensors in the canal registered more than 90 per cent full at 4.22pm.

      However, neither reached 100 per cent and both were below 90 per cent by 4.28pm, although the "high flood risk" warnings remained.

    • Dry and warm days in third week of October: Met Service

      SINGAPORE: A little less rain can be expected in the second half of October compared to the first half of the month, said the Meteorological Service in an advisory on Monday (Oct 16).

      Several dry and warm days can be expected this week, and for the rest of the second fortnight, short thundery showers are forecast to fall mostly in the afternoon on four to six days, the Met Service said. On some of these days, the showers could extend into the evening.

      It added that the passage of Sumatra squalls could bring widespread thundery showers and gusty winds between the pre-dawn hours and early morning on one or two days.

      Total rainfall for October is expected to be slightly above normal, the Met Service said. 

      The daily temperatures on most days is expected to range between 24°C and 33°C. However, the temperature could be as high as 35°C on days that are expected to be dry and warm.
