“As for rainfall — or what is referred to as significant rainfall — heavy rain is expected to begin in parts of the country by Thursday afternoon. This coincides with the moment when Super Typhoon Rosal is closest to our landmass,” he said.

Between Thursday and Friday afternoon, rainfall in Batanes may reach 200 millimeters in 24 hours.

Meanwhile, Cagayan, including the Babuyan Islands, may receive 50 to 100 millimeters of rain.

“That volume of rainfall could potentially cause widespread flooding in low-lying areas,” Estareja warned, referring to areas that may be affected by Rosal.
