Habagat, storm Gener bring heavy rains; flooding, landslides warnings up. PAGASAMANILA — The southwest monsoon or habagat and tropical depression Gener are forecast to continue to bring moderate to heavy rains over parts of Luzon and Visayas, including to areas already affected by flooding, this week, the state weather bureau PAGASA warned Monday.

This could lead to more flooding, as well as rain-induced landslides, the weather agency said.

PAGASA in its Monday morning bulletin said that beginning Monday until Thursday, moderate to intense rains could lash many Luzon and Visayas areas, including Metro Manila, due to habagat.

Calabarzon, Mimaropa, Western and Central Visayas, Negros Island Region, Quezon, Camarines Norte, and Camarines Sur could experience up to torrential rains this week.

Tropical depression Gener meanwhile is predicted to unleash heavy rains over Cagayan Valley, the Cordilleras, Ilocos Norte, Nueva Ecija, and Central Luzon, including Bulacan.

More flooding is expected in areas where heavy rains are forecast to arrive, including the already drenched parts of Metro Manila and Occidental Mindoro.

Hundreds of Occidental Mindoro residents evacuated on Sunday due to nonstop rains that brought floodwaters into their homes. The bad weather has also prompted class cancellations due to severe rains and flooding.

SIGNAL NO. 1 UP; PAGASA WARNS OF ROUGH SEAS

Tropical depression Gener at 10 a.m. was sighted off Casiguran, Aurora. It had slightly intensified to having 55 kph winds and was slowly moving west-southwestward.

Tropical Cyclone Wind Signal No. 1 — indicating strong winds of up to 61 kph — has been raised in Cagayan, including the Babuyan Islands; Isabela; Quirino; Nueva Vizcaya; Apayao; Kalinga; Abra; Ifugao; Mountain Province; Benguet; Ilocos Norte; Ilocos Sur; La Union; Pangasinan; Zambales; Tarlac; Nueva Ecija; Aurora; and the northern portion of Quezon (General Nakar, Infanta, Real), including the Polillo Islands.

PAGASA also warned of moderate to rough seas over the western and southern seaboards of Southern Luzon, the seaboards of Visayas, and the western, northern, and eastern seaboards of Mindanao. 

Sea travel could be risky for small seacrafts, including all types of motorbancas, it cautioned. 

"Mariners of small seacrafts, including all types of motorbancas, are advised not to venture out to sea under these conditions, especially if inexperienced or operating ill-equipped vessels," the weather agency said.

FORECAST TRACK FOR GENER

Gener may land in the vicinity of Isabela or Aurora within the next 24 hours and may likely emerge over the coastal waters of La Union or Pangasinan Tuesday morning, PAGASA said.

It is likely to cross mainland Luzon as a tropical depression, although the possibility of Gener intensifying into a tropical storm before hitting land cannot be ruled out.

It is forecast to leave the Philippine area of responsibility between late Tuesday night and Wednesday morning.

'PULASAN' INTENSIFIES 

Pulasan, another weather disturbance being monitored by PAGASA, was located 2,215 kilometers east of southeastern Luzon and intensified into a tropical storm, packing 65 kph winds.

Due to its distant location from the Philippines, it is not expected to directly affect any part of the country, even though it is predicted to briefly enter the northeastern tip of the Philippine area of responsibility.

Tropical storm Pulasan has a similar track to that of Bebinca, formerly Ferdie, said PAGASA.
