Current Status and Outlook Tropical Disturbance (LPA) 01W [AMANG] remains disorganized while over the South Philippine Sea, with most of its rainbands displaced to the west and north of the center…expected to accelerate west-northwestward and could make landfall along Northern Caraga tonight. 

The combination of the LPA’s rainbands and the enhanced Northeast Monsoon (Amihan) will bring moderate to heavy to at times extreme rainfall along Northern and Northeastern Mindanao, Eastern and Central Visayas, and Bicol Region. These rains is likely to produce flooding and landslides along hazard-risk areas particularly along areas once affected by TD 35W (USMAN). Please take all necessary precautions.

How strong is it? Maximum Sustained Winds (10-min avg): 35 kph near the center…Gustiness: 50 kph
