In Sunday’s 11 p.m. bulletin and today’s 4 a.m. bulletin of PAGASA, it said “ROLLY” is expected to exit the country on Tuesday morning. It is even forecast to further weaken ito a tropical depression “due to increasingly unfavorable conditions.”
At 4:00 AM Monday, Nov. 2, the center of Tropical Storm “ROLLY” was estimated based on all available data at 100 km West Southwest of Subic Bay (14.6 °N, 119.4 °E ), PAGASA said. Rolly is moving West Northwestward at 20 km/h, with maximum sustained winds of 65 km/h near the center and gustiness of up to 80 km/h.
The center of Storm “Siony,” on the other hand, was estimated based on all available data at 990 km East of Northern Luzon (17.0 °N, 131.0 °E ) at 10 p.m., Sunday, Nov. 1.

Within the day, however, it weakened until it became a tropical storm.
