Amihan, shear line to bring cold, rainy weather to most parts of Luzon this week

MANILA -- A fresh surge of Amihan or the northeast monsoon is expected to bring cold weather to most parts of Luzon this week.

According to Ariel Rojas, ABS-CBN's new resident meteorologist, the surge may bring light to occasionally moderate rains over Cordillera, Cagayan Valley, Aurora, and Quezon until Friday.

This may be enhanced by a shear line, a boundary where cold and warm air masses meet, which will fully develop on Wednesday.

The shearline will bring scattered moderate to heavy rains over Eastern Visayas and parts of Caraga Wednesday; shifting to Bicol, northern MIMAROPA, and Panay Thursday to Saturday; and moving down again to most of Visayas and northern parts of Mindanao by Sunday. 

"Flooding and landslides are expected in these areas," per Rojas.

A weather disturbance is also expected to form east/southeast of Mindanao by midweek, but it has very low chance of developing into a tropical cyclone.

Meanwhile, cloudy weather is expected in Metro Manila from Monday through Wednesday. There will be sunny spells in the morning and possible light rains Thursday to Sunday.
