PETALING JAYA: Heavy rain on Monday evening, coupled with after work traffic resulted in massive traffic jams along most roads in the Klang Valley.

Traffic on the MRR2 from Bukit Jalil heading towards the city centre, Subang to Dataran Prima and Kota Damansara, as well as the Kerinchi Link towards the Federal Highway was also slow moving.

Traffic on both sides along Jalan Hang Tuah was at a standstill, as was the traffic from Bandar Sunway heading towards the Kewajipan roundabout.

In Serdang, flash floods forced 30 primary school students to be vacated from their school.

Selangor Fire and Rescue Department operations assistant director Mohd Sani Harul said the department received a distress call at about 5.50pm.

"The water had risen about two feet, so we had to vacate the students from Sekolah Kebangsaan Sri Serdang to the Sri Serdang Rukun Tetangga hall," he said.
