Manalo said the storm’s interaction with land contributed to its continued weakening.
“Yung interaksyon nito sa lupa ay naka-contribute din sa patuloy na paghina nitong si Bagyong Maymay,” he added.
Maymay was last located 150 kilometers east-northeast of Echague, Isabela, with maximum sustained winds of 45 kilometers per hour (kph) and gustiness of up to 70 kph.
According to Manalo, the tropical storm is gradually moving away from the Philippine landmass and is expected to continue weakening.
PAGASA’s forecast track showed Maymay moving southeastward as it is gradually being drawn into the circulation of Typhoon "Dolphin," which remains outside the Philippine Area of Responsibility (PAR).
“Habang papalayo po ito sa ating kalupaan, mas pahina din ito nang pahina hanggang sa eventually maging Low Pressure Area,” Manalo said.
He added that Maymay may dissipate, weaken into a remnant low, or cease to exist as a tropical cyclone by early Friday morning.
Meanwhile, PAGASA said the southwest monsoon, locally known as Habagat, continues to affect Luzon, bringing rains across much of the island.
