MANILA—Typhoon Chedeng (Songda) weakened as it veered away from northern Philippines Friday but the state weather bureau said a remnant low pressure area is developing and will bring rains to Mindoro.

As of 10 p.m., Chedeng was located 100 kilometers east of-northeast of Basco, Batanes, packing winds of up to 185 kilometers per hour and gusts of up to 220 kph, the Philippine Atmospheric, Geophysical and Astronomical Services Administration said.

Storm signal number 3 was hoisted over the Batanes Group of Islands.

Chedeng was moving north-northwestward at 19 kph and was forcast to be 495 kilometers north-northeast of Basco, Batanes by Saturday afternoon.

However, Pagasa said a low pressure area was seen developing over the South China Sea.

It would bring heavy rains of about 100 millimeters to Mindoro Friday until Saturday, said Robert Sawi, Pagasa weather division officer-in-charge.
