Two more tropical cyclones may develop within the Philippine area of responsibility (PAR) this September, according to the Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA).

The state weather bureau is monitoring two low-pressure areas (LPAs) inside and outside PAR.

“Itong dalawang LPA na ito ay hindi natin inaalis ‘yung posibilidad na maging isang bagyo sa mga susunod na araw,” said weather specialist Grace Castañeda.

Based on PAGASA’s weather bulletin, the LPA inside PAR was spotted 830 kilometers east northeast of Luzon’s northern tip at 2 p.m. on Monday, Sept. 9.

The other LPA, which may enter PAR on September 11 or September 12, was located 2,435 km east of Eastern Visayas.

The LPAs will be named “Ferdie” and “Gener” once they enter PAR and develop into tropical cyclones.

The first typhoon this month, “Enteng,” exited PAR on Sept. 4.IMT
