Rains to continue in much of Mindanao due to shear line

MANILA, Philippines — Much of Mindanao will continue to experience rain on Wednesday due to the shear line, the state weather agency said.

In a report, state weather expert Obet Badrina specified that the shear line-induced rains would affect the Davao Region and Caraga.


A shear line refers to the convergence of the cold northeast monsoon and warm winds blowing from the Pacific Ocean.


A shear line advisory from the Philippine Atmospheric, Geophysical and Astronomical Services Administration (Pagasa) issued at 11 p.m. on Tuesday cautioned residents in the Davao Region and Caraga to brace for rainfall ranging from 50 to 100 millimeters from Tuesday evening to Wednesday night.

“Under these conditions, flooding and rain-induced landslides are possible, especially in areas that are highly or very highly susceptible to these hazards,” states the Pagasa advisory.

Badrina, however, said they expect the shear line’s effects to subside in the next few days.

Meanwhile, the northeast monsoon was forecast to still affect parts of Luzon and Visayas, based on Pagasa’s bulletin at 4 a.m. on Wednesday.

The Cordillera Administrative Region, Cagayan Valley, Aurora, Quezon, Marinduque, Oriental Mindoro, and Camarines Norte will likely experience cloudy skies with light rains due to the northeast monsoon, locally known as amihan, according to Pagasa.


“For the rest of Luzon, including Metro Manila, we may expect generally fair weather conditions, but isolated light rains are still possible due to the northeast monsoon,” Badrina said in Filipino.

Badrina further said that state meteorologists are still not seeing any low-pressure area forming within the Philippine area of responsibility.

As for the country’s seaboards, a gale warning was raised over the coasts of Northern Luzon, Central and Southern Luzon, Visayas, and Mindanao, where waves as high as 4.5 meters may be anticipated on Wednesday.
