MANILA, Philippines – Tropical Depression Usman began moving westward slowly early Friday evening, December 28, after staying almost stationary the entire afternoon.
In a bulletin issued 8 pm on Friday, the Philippine Atmospheric, Geophysical, and Astronomical Services Administration (PAGASA) said Usman is already 240 kilometers east of Guiuan, Eastern Samar.
The tropical depression continues to have maximum winds of 55 kilometers per hour (km/h) and gustiness of up to 65 km/h. It is now unlikely to strengthen into a tropical storm, after initial projections that it could. (READ: FAST FACTS: Tropical cyclones, rainfall advisories)
Usman is expected to make landfall in Eastern Samar either on Friday evening or early Saturday morning, December 29.
Signal No. 1 remains up over the following areas:
Moderate to heavy rain will continue in Bicol, Eastern Visayas, and Quezon, while light to heavy rain will prevail over Metro Manila, Mimaropa, Aurora, the rest of Calabarzon, and the rest of the Visayas on Friday evening.
On Saturday, there will also be moderate to heavy rain in Metro Manila, Calabarzon, Mimaropa, Bicol, and Aurora, as well as light to heavy rain in the Visayas.
Areas in Usman's path should be on alert for possible flash floods and landslides.
PAGASA also warned that sea travel remains risky in areas under Signal No. 1, as well as in the seaboards of Northern Luzon, the eastern seaboards of Central Luzon and Southern Luzon, and the eastern seaboard of the Surigao provinces. This is due to both Usman and the surge of the northeast monsoon or hanging amihan.
Based on its latest forecast track, Usman is expected to leave the Philippine Area of Responsibility on Monday, December 31.
Usman is the Philippines' 21st tropical cyclone for 2018. The country's average number of tropical cyclones per year is only 20. (READ: LIST: PAGASA's names for tropical cyclones in 2018)

Meanwhile, the northeast monsoon will affect Central Luzon and Northern Luzon on Saturday.
The Ilocos Region, Cagayan Valley, Cordillera Administrative Region, Central Luzon, and much of Calabarzon will have light to moderate rain from the northeast monsoon. Flash floods and landslides are possible.
The rest of Mindanao, not affected by either Usman or the northeast monsoon, will only have isolated rainshowers or thunderstorms on Saturday.
