Super Typhoon 'Betty' was last spotted 1,320 kilometers East of Central Luzon, packing maximum sustained winds of 195 kilometers per hour (kph) with gustiness of up to 240 kph. It is moving west northwestward at 25 km/h.

Strong to typhoon-force winds extend outwards up to 570 km from the center, the weather central said.

TROPICAL CYCLONE WIND SIGNALS (TCWS) IN EFFECT

Note: Wind Signals are not hoisted over the country at this time.

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. It may eventually become almost stationary between late Tuesday and early Wednesday when it will be closest to Batanes (i.e., within 250-300 km).

The weather disturbance 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).

HAZARDS AFFECTING LAND AREAS

Heavy Rainfall Outlook

Forecast accumulated rainfall from Monday early morning to Tuesday early morning

50-100 mm: Batanes, Babuyan Islands, and the northern portions of mainland Cagayan, Ilocos Norte, and Apayao.

Forecast accumulated rainfall from Tuesday early morning to Wednesday early morning
Greater than 200 mm: Batanes
  • 100-200 mm: Babuyan Islands, Ilocos Norte, Ilocos Sur, and La Union
  • 50-100 mm: Cordillera Administrative Region and the northern portion of mainland Cagayan.

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

In anticipation of possible strong breeze to gale-force conditions caused by the approaching super typhoon, Wind Signals may be hoisted in some areas of Northern Luzon (especially in the northern portion) tonight or tomorrow morning.

The enhanced Southwest Monsoon may bring strong breeze to near gale conditions with intermittent gusts beginning on late Sunday 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) this afternoon or evening.

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.

TROPICAL CYCLONES

'Bagyong Betty' is the second tropical cyclone for 2023, known as the strongest Northern Hemisphere cyclone to form in the month of May. It originated from an area of low-pressure south-southwest of Chuuk Lagoon in the central Pacific that developed into a tropical depression on May 19.

On average, there are 20 tropical cyclones that could form or enter the PAR each year. Only half of those are projected to make landfall.

PAGASA is expected to soon declare the start of the country’s rainy season, which usually begins in the second half of May or first half of June.
