Berita Harian reported that in a four-minute, 25-second video shared online, hospital staff could be seen carrying hospital equipment and motorcycles out of a flooded building.

Several social media users said in the comments that their homes and workplaces have also similarly been struck by flash floods, including in Kulai.

New Straits Times reported the hospital as saying Bangunan Lily, which houses the psychiatry and mental health specialist clinic, was inundated at about 4pm due to a drainage failure.

It said the situation was brought under control by 4.45pm, and cleaning had been completed.

Ling said the heavy rain, which started at around 2pm and only receded by 6.30pm, had caused “waterfalls” into the low-lying building.

“Based on data from the Johor Bahru irrigation and drainage department, rainwater levels were recorded as exceeding 70mm.

“The department will propose the construction of a small drain by the roadside to channel water directly into the drainage system,” he said.
