MANILA — Heavy rains may hit Metro Manila on Monday, July 22, when President Ferdinand Marcos Jr. delivers his third State of the Nation Address (SONA), an advisory from the state weather agency PAGASA said Sunday morning.

The rains are brought by the southwest monsoon or habagat, which is being enhanced by Tropical Storm Carina, according to PAGASA.

Marcos will address the nation from the Batasang Pambansa Complex in Batasan Hills, Quezon City. Hundreds of protestors are expected to take to the streets around the area.

HEAVY RAINFALL FORECAST

On Sunday, moderate to heavy rains are expected over Zambales, Bataan, and Kalayaan Islands.

On Monday, moderate to occasionally heavy rains are forecast over Metro Manila, Ilocos Norte, Ilocos Sur, Abra, Pampanga, Bulacan, Rizal, Cavite, Batangas, and Calamian Islands, PAGASA said. 

Heavy to intense rains could also arrive in La Union, Pangasinan, Benguet, Zambales, Bataan, and Occidental Mindoro on SONA day.

By Tuesday, PAGASA said heavy to intense rains could persist in La Union, Pangasinan, Benguet, Zambales, Bataan, and Occidental Mindoro.

It added that moderate to heavy rains could still be experienced over Metro Manila, Ilocos Norte, Ilocos Sur, Apayao, Abra, Pampanga, Bulacan, Rizal, Cavite, Laguna, Batangas, and Calamian Islands a day after Marcos' third SONA.

The weather bureau warned that floods and landslides could hit the areas with heavy rainfall.

CARINA SLIGHTLY INTENSIFIES

PAGASA in its 11 a.m. advisory said Tropical Storm Carina slightly intensified over the Philippine Sea. 

It is now packing winds of 85 kilometers per hour near the center and gustiness of up to 115 kph.

The agency said heavy rainfall due to the cyclone could hit residents in mainland Cagayan and Babuyan Islands from Sunday to Monday noon and could persist until Tuesday.

On Monday, Batanes may also experience heavy rains expected to last until Wednesday.

'RAPID INTENSIFICATION' LIKELY

Tropical Storm Carina will remain far from the landmass and may leave the Philippine area of responsibility on Wednesday night or Thursday early morning, PAGASA said.

It said the cyclone could "steadily intensify" in the next four days due to a favorable environment. 

"It is forecast to become a severe tropical storm by tonight and reach typhoon category tomorrow evening. Rapid intensification within the forecast period is possible," the agency said.
