Jonathan Cellona, ABS-CBN News/FileMANILA -- The Amihan and shear line is expected to bring rains all over Luzon during the second week of December, according to PAGASA's weather outlook.

The state weather bureau on Sunday said showers will be felt throughout the week over Cordillera, Cagayan Valley, and the eastern portions of Central Luzon and CALABARZON due to the northeast monsoon (Amihan) and shear line.

Rains will be felt on Monday, Tuesday, and during the weekend in northern MIMAROPA, Bicol, and northern portions of Samar, Negros, and Panay.

"Current Amihan surge will be much weaker Wednesday through Friday though a fresh surge will envelope Luzon by weekend," PAGASA said.

Meanwhile, the Intertropical Convergence Zone (ITCZ) will bring scattered rains over most of Palawan, Visayas, and Mindanao, but will subside before the upcoming weekend.

Weather in Metro Manila will mostly be overcast with passing rains during the week and "may experience longer sunny intervals during the weekend."

The state weather bureau also warned that a low pressure area may form east of Mindanao along the ITCZ inside the Philippine Area of Responsibility by Sunday and may affect the southern portion of the country on the third week of December.
