Maring made landfall in Mauban, Quezon at around 9 a.m. yesterday and moved to Laguna, Rizal, and Metro Manila, which caused massive flooding in these areas, said weather forecaster Sheila Reyes.
Among them were two teenage brothers who perished in landslide in Taytay, Rizal, just east of Manila.
The Supreme Court also suspended work in all courts in Metro Manila, Central Luzon, and Calabarzon.
In Calamba City, a flash flood washed away a riverside shanty, leaving six inhabitants including a two-year-old missing. "There was a flash flood and it washed out their two storey-house", said Noriel Habana, head of the city's disaster management office. "It just so happened it was a flash flood and they had no time to react", he said.
"In previous floodings, we had preemptive evacuation".
Some cities and provinces have chose to also suspend classes for Wednesday, September 13.
Thousands of people were ordered by local governments to evacuate from low-lying, coastal and landslide-prone areas as rain pounded the area.
It was last spotted 80 km north of Daet, Camarines Norte, packing maximum winds of up to 55 kilometer per hour near the center and gusts of up to 65 kph.
Parayno said responding workers were able to rescue 12 persons, who were brought to a hospital where the boy died upon arrival.
Meanwhile, Typhoon "Lannie" (international name: Talim) will continue to move west-northwest towards the Philippine Sea but Pagasa said that it would still have no direct effect on the country.
Both Maring and Lannie are expected to exit the Philippine area of responsibility between tomorrow night and early Thursday morning.
