Landfall now expected early Saturday morning local time with sustained winds 145 knots and gusts to 180 knots.
Note: Current 64 knot radius is 50 nautical miles and during today the cyclone is expected to intensify growing to 115 nm radius at land fall. This means most of the Northern half of Luzon Island will see 64 knot winds and higher.
Cyclone strength winds, 64 knots, are not expected to hit Manila which is more south on Luzon.
However, Manila is within the area where tropical storm wind strength is expected in addition to the expected flooding.
The system is so large 34 knot winds are expected to impact all of Luzon, all of Mindoro, Coron, half of Panay, and the Northern tips of Negros and Cebu.

Super-typhoon" is a term utilized by the U.S. Joint Typhoon Warning Center for typhoons that reach maximum sustained 1-minute surface winds of at least 65 m/s (130 kt, 150 mph).
The Philippines authority, PAGASA, besides giving typhoons a different name, further confuse matters by having a different definition of Super Typhoon.
PAGASA classifies a cyclone with at least 220 kph (118 knots) top winds for a 10 minute average as a supertyphoon, the same category as Yolanda (international name: Haiyan), which pounded the Visayas in 2013, leaving a wide trail of destruction and some 7,350 people dead or missing.
The Japanese authority JMA also shares the PAGASA definition. However, I don't believe they have locally different naming conventions.
The odd thing about the JTWC definition is J is for joint and is between US and Japan.
Maybe someday everyone could agree on what these designations are.

When it made landfall winds were 145 knots and peak gusts 175 knots
The paper reported:
As of 6 pm Friday Ompong has a vast diameter of 900 kilometers. Thus strong winds and heavy rain were felt in provinces all over Luzon. In terms of diameter, Ompong measures wider than most super typhoons, including Yolanda, which had a diameter of 600 kilometers.
Thus overall energy was potentially larger even though Yolanda had much higher core winds.
Another comparison is with hurricane Florence which struck the US.
With a diameter of about 500 miles across (800 kilometers) according to USA Today, Florence was larger than Hurricane Katrina.

Filipino forces are starting to reach more remote areas.
Toll has risen to 65 confirmed fatalities, several thousand homes, and one airport terminal extensively damaged.
Winds are down now to 70 knots average and it will make landfall in Southern China shortly.
