The rainy weather condition experienced in most parts of the country may persist until the weekend due to the effects of shear line and the northeast monsoon, also known as “amihan,” the Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA) said on Thursday afternoon, Jan. 5.

“Ang minomonitor natin ngayon ay itong shear line na nakakaapekto sa Southern Luzon at Visayas (Currently, we are monitoring the shear line which is affecting Southern Luzon and Visayas),” said PAGASA Weather Specialist Veronica Torres in a public weather forecast.

“Mostly ito ay nasa eastern part ng bansa na naapektuhan ng low pressure area (LPA) at northeast monsoon (Mostly it is in the eastern part of the country that was affected by the low pressure area (LPA) and northeast monsoon)," said Torres.

The top three areas are as follows: Daet, Camarines Norte (120.3 mm), Infanta, Quezon (102.2 mm), and Catarman, Northern Samar (88.0 mm).
