97W renamed as 98W (LOCALLY NAMED BY PAGASA AS BISING), remained at severe alert status based on latest vorticity wind over the area as its convection keeps flaring away from its LLCC, remains its threat at visayas and northern mindanao with moderate to heavy rains. As of 12p, it was centered based on NRL at 7.5N,128E or approximately at 187km east of Mindanao with maximum wind of 15-20kts and SLP of 1008mb.
Recent upper divergence shows some weakness to weak at 10kts with poleward outflow being cut by strong Ridging over to the north which acts as a steering influence over 97/98W (bising).
Convection along the area remain scattered but at level of 4-5 only due to increasing shear over its current position.
The next 12-24hrs are critical to whether 97/98W (bising) survive due to proximity over land and environmental factor slowly becoming unfavourable for the system.
