MANILA -- Tropical depression Luis weakened into a low pressure area at 8 p.m. Monday, according to PAGASA.
All remaining wind signals in Northern Luzon have been lifted.
At 10 p.m., the remnant low was in the vicinity of Peñablanca, Cagayan.
It may move away from land and eventually merge with the broad circulation of Typhoon Dolphin.
Dolphin was located more than 2,600 kilometers east northeast of Extreme Northern Luzon, outside the Philippine area of responsibility.
The typhoon is less likely to enter the PAR but may enhance the southwest monsoon or Habagat as it heads towards eastern China, where it may make landfall by weekend.
Meanwhile, a new LPA formed over the West Philippine Sea on Monday evening due to the spinning caused by the interaction of Luis' northwesterly winds with the Cordillera mountain range.
The LPA was over the coastal waters of San Fernando City, La Union at 8 p.m.
PAGASA said it is unlikely to develop into a tropical cyclone.
The LPA west of Ilocos Region and the enhanced Habagat will bring significant rainfall over the western sections of Luzon and Visayas through Wednesday:
