HAZARDS AFFECTING LAND AREAS
Aside from the rainshowers caused by the trough of ROSAL, the tropical depression is less likely to bring heavy rains in the country throughout the forecast period.
In the next 24 hours, the surge of the Northeast Monsoon partly enhanced by this tropical depression may bring occasional gusts reaching gale-force over Batanes and Babuyan Islands, and strong breeze to near-gale strength over the Ilocos Norte, the northern and eastern portions of Cagayan, and the eastern portion of Isabela
HAZARDS AFFECTING COASTAL WATERS
• Under the influence of the surge of the Northeast Monsoon partly enhanced by ROSAL, a marine gale warning is in effect over the seaboards of Northern Luzon. For more information, refer to Gale Warning #25 issued at 5:00 PM today.
• In the next 24 hours, the combined effects of the surge of the Northeast Monsoon and the tropical cyclone may also bring moderate to rough seas (1.5 to 3.5 m) over the seaboards of Central Luzon and the eastern and western seaboards of Southern Luzon. These conditions may be risky for those using small seacrafts. Mariners are advised to take precautionary measures when venturing out to sea and, if possible, avoid navigating in these conditions.
TRACK AND INTENSITY OUTLOOK
Tropical Depression ROSAL is forecast to move generally northeastward or east northeastward today through Tuesday morning before turning generally south southeastward. In the near term, ROSAL may still intensify into a low-end tropical storm within 24 hours. However, increasingly unfavorable conditions associated within the monsoon surge by late Monday will result in a weakening trend. ROSAL may become a post-tropical low embedded along the leading edge of the monsoon surge by late Tuesday or Wednesday.
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 11:00 PM today.
