Heavy rain associated with the southwest monsoon, known locally as habagat, is forecast to affect four provinces in Luzon's central region, prompting the national weather bureau to issue flood and landslide warnings and prompting local governments to ready emergency responses. The Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA) warned that areas receiving moderate to heavy rainfall could face flash floods and landslides, raising concerns for densely populated river basins.
Meteorological outlook and warnings
According to reports from Philstar.com and a PAGASA‑related post on Facebook, the habagat will continue to bring sustained rains and thunderstorms across parts of Luzon and the Visayas on Monday, September 7, 2026. The agency cautioned that "moderate to heavy rainfall" could trigger flash floods and landslides in vulnerable locations. The same Facebook post noted that the weather system is expected to linger, increasing the risk of localized flooding.
In addition to the monsoon, PAGASA is monitoring Tropical Storm "Krovanh" (formerly PILANDOK/LPA 08j) which remains outside the Philippine Area of Responsibility but could affect the periphery of the country. A separate Facebook update at 8:00 a.m. on September 6 advised the public to keep an eye on PAGASA advisories regarding the storm's progress.
"PAGASA warning of possible flash floods and landslides in areas receiving moderate to heavy rainfall," the agency posted on its official social media platform.
Local authorities' preparedness measures
Transportation officials in Metro Manila are mobilising resources to mitigate potential inundation. The TheChronicle.com.ph reported that the North Luzon Expressway (NLEX) and the Metropolitan Manila Development Authority (MMDA) are deploying sandbags, temporary barriers, and high‑capacity pumps along flood‑prone sections. These efforts aim to protect critical roadways and prevent traffic disruptions during the anticipated downpours.
Impact on schools and public services
In response to the forecast, the government ordered the suspension of classes for Monday, September 7, 2026, as confirmed by GMA Network. The pre‑emptive school closures cover affected municipalities in the four provinces, reducing the risk of students being caught in sudden floods or landslides. Public utilities are also on standby to address possible power interruptions caused by water‑related incidents.
Regional variations and broader context
While Luzon braces for heavy rains, the Visayas and parts of the central Philippines are expected to experience milder conditions. Cebu Daily News reported that Cebu will see generally fair weather with only isolated showers linked to the habagat, underscoring the uneven distribution of monsoon effects across the archipelago.
The habagat season, which typically peaks from July to September, is a critical component of the Philippines' climate, supplying essential water for agriculture but also posing recurrent flood risks in low‑lying and mountainous regions. Luzon, the country's largest island and home to the capital Manila, contains key economic corridors; thus, flooding there can disrupt trade, transportation, and daily life for millions. PAGASA, the government agency responsible for weather forecasting, plays a central role in issuing timely alerts that enable local governments and communities to enact precautionary measures.
Overall, the combination of a robust monsoon surge and the proximity of Tropical Storm Krovanh has heightened vigilance across the nation. Authorities continue to monitor rainfall intensity, update flood warnings, and coordinate emergency response teams to mitigate the potential impact on residents and infrastructure.
