Radio reports said local residents were taken by surprise by the “unusually fast” rise of flood waters.
The area is part of Camanava (Caloocan, Malabon, Navotas, Valenzuela), which is known for frequent floods whenever the high tide and rains occur simultaneously.
The local government of Malabon was said to have already deployed 6×6 trucks to aid in the evacuation.
At least 12 barangays in Malabon were already under knee-deep floods, reports said.
In Navotas, residents of at least three barangays have been evacuated.
Major roads in the areas remain closed to traffic due to the high water levels, reports said.
