Parts of Mindanao were submerged in knee-deep to neck-deep floods a day before Christmas eve as Tropical Storm Vinta continued to barrel through Mindanao.

In Cagayan de Oro City, roads in residential areas were impassable to vehicles due to floods.

Rescue boats took in people from rooftops while others took shelter on most anything above water they could find, even the top of a vehicle half-submerged in flood.

In Davao City, disaster officials made use of jet skis and inflatable rafts to rescue people from houses that have been submerged in flood waters.

As of Saturday midnight, about 31,375 individuals have been affected by the flooding in Davao City, President Rodrigo Duterte's hometown.

So far, no casualties have been reported in Cagayan de Oro and Davao City.

As of 5 a.m. Saturday, Vinta was last spotted 165 kms northwest of Zamboanga City packing maximum sustained winds of 75 kms per hour near the center and gusts of up to 90 kph, state weather bureau PAGASA said.

The storm is expected to leave the Philippine Area of Responsibility on Christmas eve.
