HAZARDS AFFECTING LAND AREAS
• Tonight through tomorrow evening, “MARING” will bring moderate to heavy with at times intense rains over Batanes, Cagayan including Babuyan Islands, Cordillera Administrative Region, and Ilocos Region. Light to moderate rains with at times heavy rains may prevail over Central Luzon and the rest of Cagayan Valley.
• The enhancement of the southwesterlies may bring rains over Visayas, Zamboanga Peninsula, Palawan, and Occidental Mindoro. For more information, refer to Weather Advisory #2 issued and the 24-Hour Public Weather Forecast at 11:00 AM and 4:00 PM today, respectively.
• Under these conditions, scattered to widespread flooding (including flash floods) and rain-induced landslides are possible especially in areas that are highly or very highly susceptible to these hazard as identified in hazard maps.
• Winds may reach gale- to storm-force strength within any of the areas where TCWS #2 is in effect. This may result to light to moderate damage to structures and vegetation.
• Strong winds (strong breeze to near gale conditions) with higher gusts are prevailing in areas where Tropical Cyclone Wind Signal (TCWS) #1 is currently in effect. This may generally bring up to very light damage to structures and vegetation.
• Due to the expansive wind field of the tropical storm and the enhancement of the southwesterlies and northeasterlies, occasionally gusts reaching strong breeze to near gale in strength are possible in the next 24 hours over the coastal and upland/mountain areas of MIMAROPA, Bicol Region, Visayas, Caraga, and Northern Mindanao that are not under TCWS.
HAZARDS AFFECTING COASTAL WATERS
• Under the influence of Tropical Storm “MARING”, a Gale Warning is in effect for eastern seaboards of Central and Southern Luzon and the northern coast of Northern Samar. For more information, refer to Gale Warning #5 issued at 5:00 PM today.
• In the next 24 hours, moderate to rough seas will prevail over the remaining seaboards of Luzon and Visayas, and the northern and eastern seaboards of Mindanao. These conditions are 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
• The tropical storm is forecast to continue moving west northwestward in the next 12 hours before turning westward towards Extreme Northern Luzon. “MARING” is forecast to gradually intensify and may be upgraded to severe tropical storm within the next 12 hours.
• On the forecast track, “MARING” is forecast move over Luzon Strait and may pass close or over the Babuyan Islands between tomorrow afternoon and Tuesday early morning. However, the possibility of a landfall over mainland Luzon is not ruled out at this time. Afterwards, the storm will continue to move westward through the remainder of the forecast period and may exit the Philippine Area of Responsibility by Tuesday morning or afternoon.
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.
