Netizens took to social media to post pictures and videos of the flash floods, including on the Federal Highway near the turnoff to Kampung Kerinchi, which have led to heavier-than-usual traffic congestion.

Astro Radio Traffic warned road users to expect a one-hour traffic jam on the Damansara-Shah Alam Elevated Expressway, or DASH, from the RRIM toll plaza.

FMT has reached out to the fire and rescue department for comment.

Berita Harian also reported that five vehicles were trapped in floodwaters at Persiaran Surian near Mutiara Damansara at about 8.10am, causing traffic congestion along the road.

Separately, the meteorological department said thunderstorms were forecast until 1pm in Kuala Lumpur and five districts in Selangor – Petaling, Kuala Selangor, Hulu Selangor, Klang and Gombak.

Heavy rain is also expected in Bandar Baharu, Kedah; Seberang Perai Selatan, Penang; and Kerian, Muallim, as well as Larut, Matang and Selama in Perak.
