What to expect

PAGASA said that Aghon could bring rain of up to 200 millimeters over Quezon province, and between 100 and 200 mm over Aurora, eastern portion of Bulacan, Rizal, Laguna, Metro Manila and Camarines Norte today.

Meanwhile, the eastern portion of Isabela, Nueva Ecija, the rest of Bulacan, the eastern portion of Pampanga, Cavite, Batangas, Oriental Mindoro, Occidental Mindoro, Romblon, Burias Island, the western portion of Camarines Sur, Cuyo Islands, Aklan, and Antique will have 50 to 100 mm of rainfall.

The state weather bureau warned of higher rainfall in elevated or mountainous areas. This can lead to flooding and landslides, especially in areas susceptible to these hazards or places that have experienced recent heavy rain.

PAGASA also said that there is a minimal to moderate risk of storm surge over the exposed and low-lying coastal areas of Cagayan, Isabela, Aurora, Central Luzon, Metro Manila, CALABARZON, Mindoro provinces, Marinduque, Romblon, Camarines Norte, Camarines Sur, western coast of Albay, Burias Island, northwest coast of mainland Masbate, and Aklan.

Sea travel is risky for small seacrafts, including all motor bancas, over the coastal waters of Marinduque and Quezon province, southern coastal waters of Batangas, and northern coastal waters of Camarines Norte.

Aghon's track

After crossing mainland CALABARZON and Polillo Islands, the tropical storm is expected to be over the waters off the east coast of Quezon province or Aurora this evening or early Monday.

During this time, Aghon will likely remain a tropical storm, although it could weaken to a tropical depression over mainland CALABARZON due to land interaction.

Starting Monday, Aghon will gradually accelerate northeastward while intensifying. It may reach severe tropical storm category by Monday.

"We are still not discounting the possibility of it passing through areas of Laguna, Rizal, the eastern side of Bulacan up to Aurora. Then it might also slightly turn towards the area of Polillo Islands and move away," PAGASA weather forecaster Benison Estareja said in Filipino.

Aghon is expected to become a typhoon by Tuesday afternoon or evening, and may exit the Philippine Area of Responsibility (PAR) on Wednesday.
