Tropical Depression Seniang continues moving west toward Mindanao and we’re already seeing heavy rains affect Caraga Region. Hinatuan, Surgiao del Sur, recorded 66 mm (2.60 “) of rainfall between 8 am and 2 pm PhST. This is expected to continue into Monday and Tuesday as the cyclone moves across Mindanao and into the Visayas.
In response to the depression, PAGASA has issued Public Storm Warning Signal #1 for much of eastern Mindanao and portions of Eastern and Central Visayas. The threat of moderate to heavy rains, with rain rates reaching up to 15 mm/hr, along with occasional gusty winds are expected in these areas. Those in low-lying areas and along river banks are warned about flash floods while those in higher terrain are cautioned against possible landslides. Later, these same rains will affect much of the Visayas and Palawan as Seniang moves westward toward the South China Sea this week.
PAGASA’s forecast is a compromise between JMA’s southerly track toward Misamis Oriental and JTWC’s northerly track toward Cebu and central Negros. However, considering this system is more of a rain threat versus a wind threat, it’s best not to focus on the track line, but rather the shaded region as the rain along the periphery of the storm will be the greatest impact.
