The state weather bureau on Monday retained Tropical Cyclone Wind Signal (TCWS) No. 1 in Batanes as Typhoon Hanna, also called by its international name Haiku, makes landfall in Kaohsiung City in Taiwan.
In its 5 AM bulletin, PAGASA said the center of the eye of Typhoon Hanna was seen 265 kilometers (km) Northwest of Itbayat, Batanes, or in the vicinity of Kaohsiung City, Taiwan.
Hanna has maximum sustained winds of 12 km per hour (kph) and gustiness of up to 16 kph and is moving south southwestward at a very slow rate.
"Due to its on-going erratic movement near the coast of Kaohsiung City, Taiwan, Typhoon HANNA is forecast to exit the PAR region within the next 6 to 12 hours," the state weather bureau said.
"Within the same period, the tropical cyclone may also weaken into a severe tropical storm due to prolonged interaction with the rugged terrain of Taiwan," it added.
In the next three days, PAGASA said Hanna will persistently enhance the southwest monsoon or habagat and bring occasional to monsoon rains over the western portion of Luzon and Antique.
Today, 50 to 100 millimeters of rainfall is expected to be experienced in Metro Manila, Cordillera Administrative Region, Tarlac, Nueva Ecija, Pampanga, Bulacan, Rizal, Cavite, Batangas, the northern portion of Palawan including Calamian and Cuyo Islands, and Antique.
Meanwhile, 100 to 200 millimeters of rainfall will be felt in Ilocos, Zambales, Bataan, and Occidental Mindoro.
PAGASA warned about possible flooding and rain-induced landslides in the aforementioned areas.
Due to the enhanced southwest monsoon, gusty conditions will also continue in the areas of Batanes, Babuyan Islands, Ilocos Region, Cordillera Administrative Region, Nueva Vizcaya, the southern portion of Aurora, Zambales, Bataan, Bulacan, Metro Manila, Occidental Mindoro, Romblon, Marinduque, the northern portion of Palawan including Calamian, Kalayaan, and Cuyo Islands, and most of CALABARZON, Bicol Region, and Western Visayas today.
The state weather bureau raised gale warning in the seaboards of Northern Luzon, the western and southern seaboards of Luzon, and the western seaboard of Visayas due to rough seas.
