Typhoon Mangkhut made landfall over Philippines' northern island of Luzon on Saturday, September 15, killing at least 16 people and causing severe material damage to the area. Tropical cyclones and typhoons are common during the monsoon season which lasts from May through November.
Individuals in the affected areas are advised to stay abreast of local weather reports, adhere to instructions given by local authorities, anticipate transportation, power, and telecommunication disruptions, and avoid flood-prone areas until the situation stabilizes. Travelers utilizing airports in southern China are advised to confirm their flight status before traveling to the airport and anticipate delays and cancelations. Remember that driving or walking through running water can be dangerous - 15 cm (6 in) of running water is enough to knock over an adult - and that floodwater may contain wastewater and chemical products; all items having come into contact with the water should be disinfected and all foodstuffs discarded.
