Klang Valley flash floods hit TTDI, Bukit Jalil, Federal Highway

Klang Valley flash floods struck on Monday afternoon after a heavy downpour. TTDI, Bukit Jalil and the Federal Highway near Amcorp Mall in Petaling Jaya were among the affected areas.

Motorists also reported flooded roads in Denai Alam and Bangsar. The worst-hit spot appears to be Kampung Melayu Subang, where the river rose well past its danger level.

Floods are not new here, as MBPJ ordered a contractor to clean drains after earlier flooding in nearby Lembah Subang.

Here is where the water rose, what the rain and river readings showed, and what drivers should watch for.

Where the roads flooded

First, the Federal Highway. Heavy traffic built up between Jalan Templer and KL Gateway at 3.27pm after water rose near Amcorp Mall.

Next, TTDI. Photos showed cars moving slowly through standing water.

Also, Bukit Jalil. Water covered parts of the road towards Puchong, according to motorists’ reports.

In Denai Alam, drivers coming in from the DASH turned back as visibility dropped in the downpour.

Meanwhile, Jalan Bukit Pantai in Bangsar saw slow-moving traffic because of the flooding.

Further out, one side of the road near the Bukit Jelutong toll plaza was hard to pass.

Then, Subang. A parking area near Proton was inundated, and several parked vehicles were partly submerged.

Also, in USJ 9, Subang Jaya, heavy rain came with strong winds.

In Denai Alam, a user also posted a fallen tree near a petrol station.

What the river and rain readings showed

First, the river. At Kampung Melayu Subang, the state drainage portal showed 18.77 metres above sea level. That is 1.37 metres above the 17.4-metre danger level, according to reports.

As a result, several roads in the village went under after the Sungai Damansara spilled over. Residents posted photos of cars almost fully covered by water.

Next, the rain. The Drainage and Irrigation Department’s portal showed 73.5mm in Seri Kembangan and 35.5mm in Taman Mayang, Petaling Jaya.

In Seri Kembangan, New Village chief Eric Hong said roads along Jalan SK 6/1 and Jalan Kuyoh were flooded. Vehicles struggled to get through.

Also, at 3.15pm, the Meteorological Department had issued thunderstorm warnings for several states, including Selangor.

Overall, such storms are familiar now. Inter-monsoon storms have already driven a surge in fallen tree emergencies.

What drivers should do

First, check traffic apps and radio updates before you set out.

Next, avoid driving through standing water. Even shallow floods can stall an engine.

Also, expect slow traffic around Amcorp Mall, Bukit Jalil and Bangsar while the water drains.

Meanwhile, residents of low-lying areas such as Kampung Melayu Subang should keep watching river levels.

No injuries or evacuations had been reported by early evening.

We will update this story as more official figures come in.

Also, give other road users room. Sudden braking on wet roads can cause rear-end crashes.

Then, plan longer trips with spare time, because detours may also be slow.

Finally, keep your headlights on in heavy rain so other drivers can see you.

Overall, the Klang Valley flash floods hit at the start of the evening rush hour, so delays may continue.
