Forecast accumulated rainfall: Tomorrow (4 September)

• 50-100 mm: Ilocos Norte.

Forecast rainfall are generally higher in elevated or mountainous areas. Under these conditions, flooding and rain-induced landslides are expected especially in areas that are highly or very highly susceptible to these hazards as identified in official hazard maps and in localities that experienced considerable amounts of rainfall for the past several days.

Furthermore, the enhanced Southwest Monsoon will bring moderate to intense rainfall in other areas of Luzon (especially along the western portions) over the next three days. For more information, refer to Weather Advisory No. 6 issued at 11:00 PM yesterday.

Severe Winds

The wind signals warn the public of the general wind threat over an area due to the tropical cyclone. Local winds may be slightly stronger/enhanced in coastal and upland/mountainous areas exposed to winds. Winds are less strong in areas sheltered from the prevailing wind direction.

• Minor to moderate impacts from strong winds are possible within any of the localities where Wind Signal No. 2 is hoisted.

• Minimal to minor impacts from strong winds are possible within any of the areas under Wind Signal No. 1.

The enhanced Southwest Monsoon will also bring strong to gale-force gusts over the following areas (especially in coastal and upland areas exposed to winds):

• Today (3 September): Ilocos Region, Nueva Vizcaya, Quirino, Zambales, Bataan, Aurora, Bulacan, Metro Manila, CALABARZON, MIMAROPA, Bicol Region, Western Visayas, Negros Island, and Northern Samar.

• Tomorrow (4 September): Ilocos Region, Abra, Benguet, Zambales, Bataan, Bulacan, Aurora, Metro Manila, CALABARZON, MIMAROPA, Bicol Region, Western Visayas, and Northern Samar.

Coastal Inundation

A minimal to moderate risk of storm surge may occur in the next 48 hours in the low-lying or exposed coastal localities of Cagayan, Isabela, Ilocos Norte, and Ilocos Sur. For more information, refer to Storm Surge Warning No. 4 issued at 2:00 AM today. Refer to official hazard maps for specific areas susceptible to storm surge inundation in these provinces.

HAZARDS AFFECTING COASTAL WATERS

In the next 24 hours, ENTENG and the enhanced Southwest Monsoon will bring the following conditions over the coastal waters of the country:

• Gale Warning is in effect over the seaboards of Northern Luzon and the eastern seaboard of Central Luzon. Sea travel is risky for small seacrafts, including all types of motorbancas. For more information, refer to Gale Warning No. 5 issued at 5:00 AM today.

• Rough seas over the western seaboard of Northern Luzon outside Gale Warning areas (2.5 to 4.0 m). Moderate to rough seas over the western seaboard of Central Luzon (1.5 to 3.0 m), the seaboards of Southern Luzon (2.0 to 3.5 m), and the western seaboard of Visayas (1.5 to 2.5 m). Mariners of small seacrafts, including all types of motorbancas, are advised not to venture out to sea under these conditions, especially if inexperienced or operating ill-equipped vessels.

• Slight to moderate seas are expected over the eastern seaboards of Visayas and Mindanao (1.0 to 2.0 m). Mariners of motorbancas and similarly-sized vessels are advised to take precautionary measures while venturing out to sea and, if possible, avoid navigation under these conditions.

TRACK AND INTENSITY OUTLOOK
