Manila: Most areas of the country will still experience rains due to three prevailing weather systems, said the weather bureau on Thursday. The shear line affecting Southern Luzon will cause scattered rains and isolated thunderstorms across the Bicol Region, Quezon, Oriental Mindoro, Marinduque, Romblon, and Palawan. According to Philippines News Agency, moderate to heavy rains in those areas could result in flash floods or landslides, the Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA) said. Cordillera Administrative Region, Cagayan Valley, and Aurora will experience light rains, while Metro Manila and the rest of Luzon will experience isolated light rains caused by the northeast monsoon or "amihan". PAGASA said the rest of the country will experience isolated rain showers or thunderstorms due to the easterlies. Luzon will continue to experience moderate to strong winds and moderate to rough coastal waters. Elsewhere, winds will be light to moderate with slight to mode rate seas. Meanwhile, PAGASA said that as of 2 a.m., no low pressure area is being monitored for possible tropical cyclone formation.
