MANILA, Philippines – Tropical Depression Samuel maintained its strength before dawn on Tuesday, November 20, as it continued moving toward the area of Dinagat Islands, Samar, and Leyte.
In a bulletin issued 5 am on Tuesday, the Philippine Atmospheric, Geophysical, and Astronomical Services Administration (PAGASA) said Samuel is already 395 kilometers east of Surigao City, Surigao del Norte. It is still moving northwest at 20 kilometers per hour (km/h).
The tropical depression continues to have maximum winds of 55 km/h and gustiness of up to 65 km/h. But it is expected to strengthen into a tropical storm since it remains over water.
Samuel is expected to make landfall in the Dinagat-Samar-Leyte area on Tuesday evening, already as a tropical storm.
Signal No. 1 is now raised in:
PAGASA warned that moderate to heavy rain may trigger flash floods and landslides in Caraga, Northern Mindanao, Eastern Visayas, Central Visayas, Western Visayas, and Bicol.
Residents of those areas should be on alert, especially if they live near rivers, in low-lying communities, or in mountainous regions. PAGASA stressed the need to monitor weather updates and follow local authorities' instructions. (READ: FAST FACTS: Tropical cyclones, rainfall advisories)

A gale warning was issued at 5 am on Tuesday for Catanduanes, the eastern coast of Albay, and the eastern coast of Sorsogon.
Seas off those areas are rough to very rough, with wave heights reaching 2.6 meters to 4.5 meters.
If Samuel maintains its speed, it would exit the Philippine Area of Responsibility on Thursday evening, November 22.

Meanwhile, the northeast monsoon or hanging amihan will continue to trigger isolated light rains in the Ilocos Region, Cordillera Administrative Region, Cagayan Valley, and Central Luzon on Tuesday. But PAGASA said there will be "no significant impact."
Metro Manila and most of Calabarzon will only have localized thunderstorms on Tuesday. But flash floods and landslides are possible if the thunderstorms become severe.
