It can be dangerous at the summit of Mt Kinabalu when there is heavy rain and strong wind. I found this video in youtube.com showing flood on the Summit of Mount Kinabalu.
Therefore, when the weather is bad during the night, your mountain guide* may cancel the trip from Laban Rata to the Summit of Mt Kinabalu.
* At least one mountain guide will be assigned to you when you start the climb. The climbing package you book with Sutera Sanctuary Lodges or Mountain Torq for a place to stay at Laban Rata includes service of mountain guides. You can find more about the mountain guides here.
