Super Typhoon "Mangkhut," known in the Philippines as Ompong, made landfall in Baggao, Cagayan at 17:40 UTC on September 14 (01:40 PHT, September 15), 2018. The system had maximum sustained winds near 268 km/h (167 mph), making it a Category 5 storm on the Saffir-Simpson Hurricane Wind Scale. Though this is not a super typhoon under PAGASA's classification system, it remains a powerful tropical cyclone with a huge diameter of 900 km (560 miles) and one of the strongest typhoons to hit the Philippines since records began. Its next landfall is expected south of Hong Kong around 12:00 UTC on September 16 (Category 4).
Mangkhut is covering the entire northern and central parts of the main island of Luzon and combined with seasonal monsoon rains, it could bring heavy to intense rains that could set off landslides and flash floods.
Tropical Cyclone Warning Signal #4 is in effect in parts of Luzon, Visayas and Mindanao.
The National Disaster Risk Reduction and Management Council estimated that at least 5.2 million people are in the path of the typhoon. Thousands of people have been evacuated in Cagayan and thousands more in other areas.
More than 4 800 passengers have been stranded in various ports, Rappler reports. Domestic and international flights have been canceled and classes suspended in various regions.
The Southwest Monsoon (Habagat) enhanced by the typhoon will bring gusty winds with occasional moderate to heavy rains over Visayas, while scattered light to moderate to at times heavy rains over Palawan, Zamboanga Peninsula, Northern Mindanao and Caraga, PAGASA said.
Residents in these areas, especially those living near river channels, in low-lying areas and in mountainous areas, are advised to take appropriate actions against possible flooding and landslides, coordinate with local disaster risk reduction and management offices, and to continue monitoring for updates.
Possible storm surge height in surge-prone areas: up to 6 m (20 feet) in Cagayan and Ilocos Norte, up to 3 m (10 feet) in Isabela and up to 2 m (6.5 feet) in Ilocos Sur, La Union and Pangasinan.
Fisherfolks and those with small seacrafts are advised not to venture out over the seaboards of areas with TCWS and the seaboards of Visayas and of Mindanao.
