In the 12th severe weather bulletin issued by PAGASA on December 2, 2019, reported that prior to its first landfall, the southern eyewall of Typhoon Kammuri brought violent winds and intense rainfall over the neighboring province of Northern Samar.
Photos and video footage from the towns of Mapanas and Gamay, both located on Northern Samar's Pacific side, show severe flooding and high winds from the typhoon.
Hours later, Kammuri made its first landfall near Gubat, Sorsogon with winds equivalent to a Category 4 hurricane.
In Northern Samar, winds were reported to reach as up to 135 km/h (84 mph) with a total accumulated rainfall of 605.5 mm (23.8 inches) within the course of 24 hours on December 2.

The Bicol Region (Region V) was impacted the most by the typhoon.
After the passage of the storm, roads between regions, especially routes from the Bicol Region towards Manila were not passable due to fallen branches and uproot trees.
Several vehicles and passengers were stranded along highways due to this.
On December 4, the provinces of Albay and Sorsogon, and the city of Naga were issued a state of calamity after widespread damages were seen.
The region's Department of Social Welfare and Development (DSWD) estimated that an estimated 130,000 children were affected by the storm.
In Camarines Sur, about 293 classrooms suffered from major damages while the province of Albay had a total of 883 classrooms damaged as of December 5.
By December 6, Catanduanes experienced heavy damages and therefore, a state of calamity was issued.

On December 4, Northern Samar's Province Disaster Risk Reduction and Management Council (PDRRMC) recommended a state of calamity, and shortly after, it was raised in two towns: Catarman and Gamay.
Massive destruction along with widespread flooding, damaged houses, landslides and even weak communication signal prompted their local government to issue the state of calamity in the two towns.
224,171 individuals were affected by Kammuri (Tisoy) in Northern Samar, and based on post-disaster assessment, about 28,577 houses were damages while an additional 3,774 were washed out by extreme flooding.
Power outages were seen in many villages, and the Northern Samar Electric Cooperative stated that power supply would be restored in Catarman and nearby towns by Christmas Day, but other towns could still suffer from no power until after Christmas.
Moreover, Kammuri's rain bands extended to as far north as Cagayan Valley, where, with the inclusion of the northeastern monsoon, saw one of the worst flooding in decades for the northern region.
Roughly 66,000 people have evacuated their homes due to extreme flooding and torrential flooding.
On December 6, state of calamity was raised.
Severe flooding in 18 areas in the province damaged agriculture and paralyzed transportation.

As of January 22, 2020, the NDRRMC stated that at least 17 people were dead and at least 318 were injured.
There has been an estimated damages of ₱6.65 billion (US$130 million) across the nation and about ₱95.7 million (US$1.87 million) to relief efforts and assistance.
Totals of 2,249 damaged schools and 558,844 damaged houses, of which 63,466 were "totally" damaged, were reported.
121 road sections and 5 bridges were damaged due to Kammuri, of which six road sections and one bridge were still considered impassable a week after landfall.
