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.

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.

More thunderstorms expected in first half of November: Met Service

SINGAPORE: More thunderstorms can be expected in the first half of November, the Meteorological Service said in an advisory on Wednesday (Nov 1).

November is normally the second wettest month of the year after December, and "short-duration moderate to heavy thundery showers" are forecast mostly in the afternoon on six to eight days of the month, said the Met Service.

On some of these days, the showers could extend into the evening, and heavy lightning can also be expected, it added.

There could also be widespread thunderstorms and gusty winds between the pre-dawn hours and early morning, the forecaster said.

Rainfall for the first fortnight of the month is expected to be above normal.

The daily temperature for the first half of the month is forecast to range between 24°C and 33°C. However daily maximum temperatures could reach a high of 34°C on a few days, said the Met Service, especially on fine weather days with few clouds and light winds.

RELATIVELY WET OCTOBER - EXCEPT FOR A FIVE-DAY HOT SPELL

Except for its third week, October was a relatively wet month, the Met Service said. About half of Singapore received above normal rainfall for the month.

October saw 21 rain days, meaning days on which at least 0.2mm of rain was recorded. This equalled the highest number of such days recorded for October in 1985 and 2003.

The heaviest daily rainfall recorded during the period was 129.8mm around Tuas on Oct 12.

The third week of the month, however, saw warm and dry days as the south-west monsoon eased. That week alone saw five days during which the daily maximum temperature exceeded 34°C, the Met Service said.

The daily temperature for the month ranged between 22.6°C and 35.3°C. The mean monthly temperature recorded for the month was 28.1°C, which is 0.5°C warmer than the long-term mean for October.

More wet weather in first half of December: Met Service

SINGAPORE: Wet and rainy weather is expected to continue in the first two weeks of December, the Meteorological Service said in a weather forecast on Thursday (Nov 30).

Short, moderate to heavy showers with thunder can be expected on five or six days in the afternoon and evening.

On one or two days, widespread thundery showers with occasional windy conditions in the early morning can also be expected, said the Met Service.

Around the second week of the fortnight, a monsoon surge could develop and bring a few days of cooler temperatures, windy conditions and heavy rain to Singapore.

Rainfall for the first fortnight of December is forecast to be well above normal, the Met Service said.

The daily maximum temperature for most days in the first half of December is likely to range between 31°C and 32°C.

However, a few rainy days during this period might drop the daily maximum and minimum temperatures to 29°C and 22°C respectively.

With the onset of the northeast monsoon, two to four episodes of monsoon surges can be expected from December to January, bringing prolonged, widespread rainfall that can last between two and five days, it added.

The cool thundery weather that descended on the island as the curtains were drawn on 2017 looks set to continue over the next few days.

Temperatures fell to as low as 23 deg C yesterday, while rain continued to fall throughout the day amid the New Year's Eve celebrations.

The thundery showers are due to a north-east monsoon surge in the South China Sea.

Singapore and the surrounding region are experiencing the wet phase of this monsoon, which typically lasts until January, so the rain is forecast to persist for a few days.

That will also mean temperatures today will range from just 23 deg C to 29 deg C.

The same weather pattern brought lower temperatures throughout December. The lowest temperature for the first half of the month was 22.3 deg C - recorded on Dec 14.

The lowest temperature recorded here was 19.4 deg C on two days in January 1934, said the National Environment Agency.

A version of this article appeared in the print edition of The Straits Times on January 01, 2018, with the headline 'It's cool and wet as S'pore enters new year'
