MANILA (UPDATED) - Tropical Cyclone Wind Signal No. 1 remains hoisted over provinces in the northern part of Luzon even as Typhoon Betty weakened slightly, the state weather bureau said Sunday.

In its 5 p.m. weather bulletin, PAGASA said parts of northern Luzon will continue to experience rains until Tuesday morning.

Signal No. 1 remains hoisted over the following areas:

• *Batanes
• *Cagayan including Babuyan Islands
• *Isabela
• *Apayao
• *Ilocos Norte
• *Northern and central portions of Abra (Tineg, Lacub, Lagayan, San Juan, Lagangilang, Licuan-Baay, Malibcong, Danglas, La Paz, Dolores, Tayum, Bucay, Sallapadan, Daguioman, Bucloc, Boliney)

The eastern portion of Babuyan Islands and the northeastern portion of mainland Cagayan may also experience up to 200 millimeters of rainfall until Tuesday morning, while Batanes, Babuyan Islands and the northern portion of Benguet may experience rainfall greater than 200 mm from Wednesday afternoon, PAGASA said.

Betty will also enhance the southwest monsoon (habagat), PAGASA said, which may bring monsoon rains over the western portions of Calabarzon Mimaropa and Western Visayas from Monday until Wednesday.

Betty, the country’s second typhoon this year, was last located 630 kilometers east of Tuguegarao City, Cagayan, packing maximum sustained winds of up to 165 kilometer per hour near the center, with gusts of up to 205 kph.

It is expected to move west northwest or northwest for the next 36 hours before gradually decelerating.

“The typhoon will likely become slow-moving to almost stationary by Tuesday while over the waters east of Batanes. It will then move northward or north northeastward by mid Wednesday towards the sea east of Taiwan,” PAGASA also said.

Meanwhile, the Philippine Red Cross said it is ready to deploy its food trucks and other assets in areas affected by the typhoon.

“As tropical cyclone Betty (international name: Mawar) approaches the extreme northern part of the country, Gordon assured the public that PRC chapters in the typhoon’s path are ready to respond with food trucks, along with other PRC disaster response equipment, such as amphibians, rescue boats, ambulance units, 6x6 trucks, payloaders, and water tankers,” PRC said in a statement.

PRC also said 2 of its water tankers have been prepositioned in Nueva Vizcaya and Olongapo, along with relief items, food packs, sleeping packs and water containers.

SCATTERED RAINS OVER PARTS OF PH THIS WEEK

Meanwhile, PAGASA said the typhoon-enhanced southwest monsoon or habagat will start on Tuesday, and will persist until the weekend, causing scattered rains over several parts of the country.

In its weekly weather outlook for May 29 to June 4, PAGASA said parts of Cagayan Valley, Cordillera and Ilocos region will experience rains with gusty winds on Monday due to the typhoon, while Mimaropa, Visayas, Bangsamoro Autonomous Region in Muslim Mindanao and Zamboanga peninsula will also experience rains due to the habagat precursor southwesterly winds.

Metro Manila, on the other hand, will be sunny and warm with low chance of rain throughout the day, with afternoon thunderstorms by Tuesday.

From Tuesday to Thursday, Ilocos region, western Cordillera, northern Zambales, Mindoro, Palawan, Western Visayas and Zamboanga peninsula will experience heavy to intense monsoon rains. Northern Luzon, Central Luzon, Calabarzon, Bicol and the rest of Visayas will also experience scattered rains.

Scattered rains are also experienced over Metro Manila by Wednesday as habagat starts, while monsoon rains will be expected from Thursday until weekend.

Monsoon rains will also prevail over western Calabarzon, Mimaropa and western Visayas from Friday to mid-Saturday, while scattered rains may persist in the same area during the rest of the weekend.

PAGASA said Betty may exit the Philippine area of responsibility by Friday.
