MANILA - Tropical depression Neneng has left the Philippine area of responsibility (PAR), state weather bureau PAGASA said Tuesday morning.
In its 5 a.m. bulletin, Neneng was last spotted at 295 kilometers west of Basco, Batanes.
PAGASA also lifted the tropical cyclone warning signal number 1 over Batanes.
However, the trough of Neneng will continue to bring scattered light to moderate to at times heavy rains over Ilocos Provinces, Cordilllera Administrative Region, and Cagayan Valley.
PAGASA warned residents living in these areas, especially those near in river channels, low-lying areas, and mountainous areas, against possible flooding and landslides.
Meanwhile, typhoon Mangkhut has maintained its strength as it moves closer to the Philippines.
The typhoon, to be named locally as Ompong once it enters PAR, is currently packing maximum sustained winds of up to 160 kilometers per hour (kph), with gusts of up to 195 kph.
PAGASA said the eye of the typhoon was last located at 1,820 kilometers east of Southern Luzon. It is moving at a speed of 30 kph.
Mangkhut is expected to enter PAR on Wednesday, September 12, and will threaten Northern Luzon by Friday.
Heavy rains and strong winds are expected over the provinces of Cagayan, Isabela, Apayao, Kalinga, Abra, Ilocos Norte, and Batanes.
The state weather bureau earlier said a tropical cyclone warning signal advisory may be raised over Cagayan Valley as early as Thursday, September 13.
Under PAGASA's tropical cyclone intensity scale, a typhoon has to reach in excess of 220kph maximum sustained winds to be categorized as a super typhoon.
