MANILA, Sept. 20 (Xinhua) -- A low pressure area (LPA) or brewing storm was spotted off the Philippines' Pacific coast, a week after typhoon Mangkhut hit northern Philippines triggering landslides and floods that killed dozens of people, the meteorologist said on Thursday.

According to the Philippine Atmospheric Geophysical and Astronomical Services Administration (PAGASA) meteorologist Gener Quitlong, the weather system was located 2,300 km off Mindanao and is expected to enter the Philippines on Friday evening or Saturday morning.

It could intensify into a storm by Sunday or Monday and will be named Paeng, he told local radio DZMM.

The potential Paeng is unlikely to hit land, but will hover close to Batanes and may enhance the southwest monsoon, Quitlong added.

Several northern Philippine provinces over last weekend bore the brunt of Mangkhut's onslaught, resulting in a total of more than 70 people died.

Typhoons hit the Philippines around 19 times a year, bringing strong winds and heavy rains, resulting in flooding, great damage to crops, houses and building.

In 2013, super typhoon Haiyan devastated the central Philippines, killing more than 6,000 people. In 2009, typhoon Ketsana also caused massive flooding in Metro Manila, killing more than 700.
