Among those old enough many Filipinos may still remember -- when many regions of the Philippines have marked dry and wet seasons, Mindanao was supposed to be free of typhoons, and the months of December to February were supposed to be "cold months" and free of typhoons in the Philippines.
Fast forward to the present, we end 2017 with a devastating typhoon [Typhoon Vinta (Tembin)] that ravaged Lanao Del Norte, and other provinces in Mindanao. This is the third catastrophic typhoon during this last decade that wrecked havoc in Mindanao during the month of December.
During the past couple of years, the typhoon season seems to begin as early as January and as of 2017 end as late as December. In this regard, PAGASA issued on 2018 New Year day the development of a low pressure area (LPA) east of Mindanao that could develop a tropical depression advisory (TDA) the next few days, affecting Surigao City, Surigao del Norte, CARAGA, Northern Mindanao and Visayas.
