The immediate forecast predicts widespread heavy rainfall, with northern regions expecting over 300 mm (11 inches) on Saturday and Sunday, raising alarm about potential flooding and landslides. Up to 270 km/h winds and waves reaching 15 meters (49 feet) are also anticipated. While the capital, Manila, is predicted to face lesser winds as the storm moves north, the threat remains critical as Man-Yi crosses the populous island of Luzon before moving offshore by Monday.

The Secretary of Civil Defense, Ariel Nepomuceno, has urged compliance with evacuation orders, highlighting the dangers of saturated ground conditions susceptible to landslides. The local populace has expressed fear and trauma from past calamities, as exemplified by residents like Glenda Llamas, who voiced concern over their safety in evacuation shelters.

Although typhoons are frequent in the Philippines, weather experts note that it is unusual to witness so many storms simultaneously during November. The recent streak of severe weather includes Tropical Storm Trami, Typhoon Kong-rey, and Typhoon Usagi, each bringing significant rainfall and fatalities. The UN's climate change body suggests that while the total number of tropical storms may not increase, their intensity is likely to grow due to climate change.

As key areas prepare for the impact of Man-Yi, the nation remains on high alert, grappling with the effects of this relentless typhoon season.
