On 17 July 2018, Tropical Storm Son-tinh (locally known as Henry) made landfall in Cagayan (northeast Philippines). Although the storm exited the Philippine Area of Responsibility (PAR) the same day, it enhanced the habagat (local name for the annual southwest monsoon) which has been affecting the country since early July. On 19 July, Severe Tropical Storm Ampil (locally known as Inday) made landfall on the eastern side of the country, causing more rain over the western part of the Philippines as it further enhanced the habagat. Ampil exited PAR on 20 July. Tropical depression Josie, which formed inside PAR on 21 July exacerbated the situation further, bringing more rain to the already saturated countryside and cities. The habagat usually starts in June or July in the Philippines and generally lasts until early September.

To date, the impacts of this monsoon season have been enhanced by the three weather disturbances, bringing scattered and widespread heavy rain and flooding over the Cordillera Administrative Region, National Capital Region, CALABARZON, Western Visayas, Ilocos Region, Cagayan Valley and Northern Palawan. Residents of these regions, particularly those living near rivers, in low-lying areas or mountainous areas, have been advised by the Philippine government to take actions against flooding and landslides. Evacuations have been ordered in some areas.

As of 25 July, the Department of Social Welfare and Development reports that a total of 288,860 families (1,279,943 people) in 1,136 barangays (communities) in 21 provinces have been affected by the combined effects of the habagat and the weather disturbances. Of these affected people, 12,127 families (48,830 people) remain at 293 evacuation centres (ECs) while a further 120,286 households (484,721 people) were served or are being supported by the government outside ECs while staying with host families or friends.
