Current Status and Outlook
Super Typhoon YUTU (ROSITA) has slightly weakened while maintaining its westerly track over the Philippine Sea during the past six hours. This howler is now endangering Northern & Central Luzon as the system’s forecast track continues to dig slightly to the south.
24-hr Outlook: On Monday morning, YUTU (ROSITA) will be downgraded to a Typhoon as it starts to veer to the West-Southwest @ 16 kph across the Philippine Sea, due to the strong surge of the Northeast Monsoon (Amihan).

However, the enhanced Northeast Monsoon (Amihan) is now affecting the Northern and Eastern Luzon including Bicol Region and Northern Visayas, where moderate to strong winds of 30-55 kph along with passing scattered rain showers and thunderstorms will be expected.
