Typhoon BETTY will also enhance the Southwest Monsoon and:
• Monday: Monsoon rains are possible over MIMAROPA and Western Visayas
• Tuesday: Monsoon rains are likely over MIMAROPA and Western Visayas.
• Wednesday: Monsoon rains are likely over Western Visayas and the western portion of Luzon.
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) are possible within any of the areas where Tropical Cyclone Wind Signal No.1 is currently in effect. Such conditions may begin on late Sunday or on Monday.
• The enhanced Southwest Monsoon may also bring strong breeze to near gale conditions with intermittent gusts beginning on tomorrow evening or early Monday over Visayas, the eastern portion of Central Luzon, the eastern and southern portion of Southern Luzon, and the northern portion of Mindanao. The western portion of Luzon may also experience similar conditions beginning on Tuesday or Wednesday.
HAZARDS AFFECTING COASTAL WATERS
• Under the influence of BETTY, a Marine Gale Warning is in effect over the northern and eastern seaboards of Northern Luzon, eastern seaboards of Central and Southern Luzon, and the eastern seaboards of Visayas and Mindanao. For more information, refer to Gale Warning #1 issued at 5:00 PM today.
• In the next 24 hours, moderate to rough seas (1.2 to 2.8 m) are also possible for the southern seaboards of Southern Luzon and the remaining seaboards of Visayas that are not under any gale warning. Marines of small seacrafts are advised to take precautionary measures while venturing out to sea and, if possible, avoid navigating in these conditions.
TRACK AND INTENSITY OUTLOOK
• BETTY is forecast to track west northwestward or northwestward in the 72 hours while gradually decelerating. The typhoon will likely become slow-moving to almost stationary by Tuesday while over the waters east of Batanes. BETTY will resume moving towards the north or north northeast by mid Wednesday.
• This typhoon is forecast to remain as a typhoon throughout the forecast period, although it is expected to gradually weaken until Tuesday. Afterwards, increasingly unfavorable environment while moving northward or north northeastward on Wednesday or Thursday will result in a faster weakening rate.
Considering these developments, the public and disaster risk reduction and management offices concerned are advised to take all necessary measures to protect life and property. Persons living in areas identified to be highly or very highly susceptible to these hazards are advised to follow evacuation and other instructions from local officials. For heavy rainfall warnings, thunderstorm/rainfall advisories, and other severe weather information specific to your area, please monitor products issued by your local PAGASA Regional Services Division.
The next tropical cyclone bulletin will be issued at 5:00 AM tomorrow.
