“Hitting the north of Luzon Island the hardest, I worry about rice crops among the step farmers up north in Ifugao and north,” explained Karinna Angeles, a nurse and humanitarian resources coordinator with The RINJ Foundation.

“Our helpline is open, and connections can be made from a smartphone at rinj.org/helpline and at +16477399279 on Telegram, Signal and WhatsApp. We are getting lots of questions, many we refer to PAGASA.”

Typhoon Betty Decelerates While Slowly Moving Northward Over The Sea East Of Batanes

Hazards Affecting Land Areas

  • Heavy Rainfall Outlook
  • Forecast accumulated rainfall from today to tomorrow afternoon
  • 50-100 mm: Batanes, Babuyan Islands, Ilocos Norte, Ilocos Sur, La Union, and the western portions of Abra and Benguet.
  • Under these conditions, flooding and rain-induced landslides are possible, especially in areas that are highly or very highly susceptible to these hazard as identified in hazard maps and in localities that experienced considerable amounts of rainfall for the past several days.
  • For more information on the areas affected by rains from the Southwest Monsoon enhanced by BETTY, refer to the Weather Advisory #3 for Southwest Monsoon issued at 11:00 AM today and the 24-Hour Public Weather Forecast at 4:00 PM today.
  • Severe Winds
  • Wind Signals in some areas of Luzon have been downgraded.
  •  Minor to moderate impacts caused by gale-force winds remain possible within the areas where Wind Signal No. 2 is hoisted. Minimal to minor impacts from strong winds (i.e., strong breeze to near gale strength) are also possible within any of the areas where Wind Signal No.1 is currently in effect.
  • The enhanced Southwest Monsoon and outer periphery of the typhoon circulation will also bring occasional gusts in the next 24 hours over Bicol Region, Western Visayas, Aurora, Quezon, Mindoro Provinces, Marinduque, Romblon, Northern Samar, and the rest of Cordillera Administrative Region and Ilocos Norte that are not under any Wind Signal.
  • HAZARDS AFFECTING COASTAL WATERS
  • Under the influence of Typhoon BETTY and the enhanced Southwest Monsoon, a marine gale warning remains in effect over the seaboards of Northern Luzon, eastern seaboards of Central Luzon, Southern Luzon, and Visayas. For more information, refer to Gale Warning #7 issued at 5:00 PM today.
  • TRACK AND INTENSITY OUTLOOK
  • Typhoon BETTY is forecast to generally move slowly northward today until tomorrow over the waters east of Batanes. Afterwards, the typhoon will gradually accelerate north northeastward on Thursday and northeastward on Friday, bringing its center over the waters southeast of the Ryukyu Islands. Typhoon BETTY may exit the Philippine Area of Responsibility on late Thursday or Friday early morning.
  • This typhoon is forecast to steadily weaken over the next five days due to cooler ocean waters (caused by upwelling of cooler waters in its wake), dry air intrusion, and increasing vertical wind shear. BETTY may be downgraded into a severe tropical storm on late Thursday or early Friday and into a tropical storm on late Friday or early Saturday. However, given the extent of the effect of dry air intrusion on the typhoon, a faster weakening rate within the forecast period is not ruled out.

  • Thursday: Monsoon rains likely over the western portions of MIMAROPA; possible over the Ilocos Region and the western portions of Central Luzon, CALABARZON and Western Visayas.
  • Under these conditions, flooding and rain-induced landslides are likely, especially in areas that are highly or very highly susceptible to these hazard as identified in hazard maps and in localities that experienced considerable amounts of rainfall for the past several days.
  • Severe Winds
  • Minor to moderate impacts caused by gale-force winds are likely within the areas where Wind Signal No. 2 is hoisted. Minimal to minor impacts from strong winds (i.e., strong breeze to near gale strength) are possible within any of the areas where Wind Signal No.1 is currently in effect.
  • Typhoon BETTY is starting to enhance the Southwest Monsoon. Occasional gusts are possible in the next 24 hours over localities in the eastern portion of Central Luzon, eastern and southern portions of Southern Luzon that are not under any Wind Signal, and most of Visayas. Such conditions are more likely in coastal and exposed upland/mountainous areas. The western portion of Luzon may experience similar conditions beginning tomorrow or Wednesday.
  • HAZARDS AFFECTING COASTAL WATERS
  • Under the influence of BETTY, a marine gale warning remains in effect over the northern and eastern seaboards of Northern Luzon, eastern seaboards of Central Luzon, the eastern and southern seaboards of Southern Luzon, the eastern and western seaboards of Visayas, and the eastern seaboard of Mindanao. For more information, refer to Gale Warning #4 issued at 5:00 AM today.
  • TRACK AND INTENSITY OUTLOOK
  • On the track forecast, BETTY will move generally northwestward slowly today and may become slow-moving or almost stationary from tomorrow to mid-Wednesday while over the waters east of Batanes. Afterwards, the typhoon will turn north northeastward or northeastward on late Wednesday or Thursday and gradually accelerate towards the waters east of Taiwan and the southern portion of Ryukyu Islands. BETTY may exit the Philippine Area of Responsibility (PAR) on Friday.
  • This typhoon is forecast to steadily weaken over the next five days due to cooler ocean waters (caused by upwelling of cooler waters in its wake) and dry air intrusion. BETTY may be downgraded into a severe tropical storm on late Thursday or early Friday and into a tropical storm on late Friday or early Saturday.

  • Forecast rainfall are generally higher in elevated or mountainous areas.
  • In areas that will not be directly affected by the super typhoon, monsoon rains from the enhanced Southwest Monsoon are possible over the western sections of MIMAROPA, Visayas, and Mindanao tomorrow. On Monday and Tuesday, monsoon rains are likely over the western sections of MIMAROPA and Western Visayas, and possible over the rest of MIMAROPA and Western Visayas.
  • Under these conditions, flooding and rain-induced landslides are likely, especially in areas that are highly or very highly susceptible to these hazard as identified in hazard maps and in localities that experienced considerable amounts of rainfall for the past several days.
  • Severe Winds
  • Strong winds (strong breeze to near gale strength) will be experienced within the areas where Tropical Cyclone Wind Signal No.1 is currently in effect.
  • The enhanced Southwest Monsoon may bring strong breeze to near gale conditions with intermittent gusts beginning on tomorrow evening or early Monday over Visayas, the eastern portions of Central and Southern Luzon, and the northern and eastern portions of Mindanao.
  • HAZARDS AFFECTING COASTAL WATERS
  •   In the next 24 hours, the eastern seaboards of Luzon and Visayas will experience moderate to rough (1.5 to 3.5 m) seas, which may become rough to very rough (2.5 to 5.0 m). The northern seaboard of Luzon may also experience moderate to rough seas (1.5 to 3.0 m) this morning through afternoon and rough seas (2.5 to 4.0 m) beginning tonight.
  • Mariners of small seacrafts are advised to take precautionary measures when venturing out to sea and, if possible, avoid navigating in these conditions. A marine gale warning may be issued within the day in anticipation of these conditions.
  • TRACK AND INTENSITY OUTLOOK
  •  Over the weekend, Super Typhoon BETTY is forecast to track generally west northwestward. On Monday, the tropical cyclone will turn northwestward and decelerate as it moves over the waters east of Extreme Northern Luzon. BETTY may eventually become almost stationary between late Tuesday and early Wednesday when it will be closest to Batanes (i.e., within 250-300 km).
  • BETTY is forecast to remain as a super typhoon over the weekend. Although it will likely maintain its strength for the next 36-48 hours, short-term intensification is not ruled out especially in the next 12 to 24 hours. However, this tropical cyclone may begin weakening considerably on Monday or Tuesday during its slowdown period over the waters east of Batanes due to potential unfavorable conditions (e.g., effect of upwelling of cooler ocean water and dry air intrusion).Citing PAGASA (dost.gov.ph)
