It has slightly intensified, now with sustained winds of 165 kph and gusts up to 205 kph. It is moving west southwestward at 25 kph.

It may be assigned the local name Neneng once it enters the PAR.
The public is advised to continue monitoring updates on the weather and take the necessary preparations.
