Tropical Depression 29W (Bagyong Onyok) continues to move closer to the Philippine Islands this morning. The center of 29W was last located approximately 460km east northeast of Davao City. Maximum sustained winds are at 45kph with gusts of up to 65kph. TD 29W is currently moving westward at 15kph.

As of 5am this morning, PAGASA has raised Public Storm Warning Signal #1 for Surigao del Sur, Siargao Island, Surigao del Norte, Dinagat Province, Misamis Oriental, Camiguin, Agusan del Norte, Agusan del Sur, Davao Oriental, Davao del Norte, Compostela Valley, Bukidnon, Lanao del Norte, Lanao del Sur, Misamis Occidental, Davao del Sure, and North Cotabato.

Latest satellite image shows convection associated with TD 29W have begun to move in to parts of Visayas and Mindanao bringing widespread light to moderate rains. TD 29W itself, however, is struggling to maintain organization due to unfavorable conditions in the area. The low-level circulation center is left fully exposed and we don't expect any intensification occurring as it tracks towards Southern Philippines.

COAMPS 48-hr Rainfall Forecast (NOT OFFICIAL!)

Despite the lack of intensification, we are still expecting widespread heavy rains to affect portions of Southern Philippines. The image above shows a 48-hour forecast for rainfall accumulations and we can see areas receiving up to 200mm (if not more) of rainfall during that period. Landslides and flashfloods are possible especially in areas placed by PAGASA under Signal #1.

If you live in these areas, please consult your local officials for the latest warnings in regards to the approaching depression.

  1. Onyok is one of the strongest typhoon that caused tragedy in the Philippines. Hope there will never be any typhoon similar to this again. Office Supplies in Davao
