HAZARDS AFFECTING LAND AREAS
Heavy Rainfall Outlook
Forecast accumulated rainfall for the next 24 hours (from this early morning to tomorrow early morning)
• Up to 25 mm in most areas of Central Luzon, Metro Manila, and CALABARZON, reaching 50 mm in a few locations (mostly in Central Luzon and northern Quezon) caused by scattered rainshowers and thunderstorms
Under these conditions, isolated flashfloods and rain-induced landslides remains possible, especially in areas that are highly or very highly susceptible to these hazards as identified in hazard maps and in localities that experienced considerable amounts of rainfall for the past several days.
Areas under Wind Signal No. 1 may experience strong winds (strong breeze to near gale strength) associated with the tropical depression which may cause minimal to minor impacts to life and property. However, winds are likely to weaken over the next several hours.
HAZARDS AFFECTING COASTAL WATERS
In the next 24 hours, moderate to rough seas (1.2 to 3.0 m) may be experienced over the western seaboards of Northern Luzon, and the northern and eastern seaboards of Luzon. Mariners of small seacrafts 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 “AMANG” is forecast to weaken into a low pressure area within 12 hours as it moves towards Polillo Islands and northern mainland Quezon.
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.
