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. It was moving West Northwestward at 30 km/h with maximum sustained winds of 65 km/h near the center and gustiness of up to 80 km/h, the same speed as Rolly.
“Rolly” (Goni) was earlier described as the strongest typhoon to enter the Philippines this year with 225 km/h maximum sustained winds and gusts of up to 310 km/h as of 5 a.m. Sunday, Nov. 1 when it developed into a super typhoon and first made landfall over Bato, Catanduanes. With its intense winds early Sunday, it was comparable to the 2013 Super Typhoon Haiyan that killed more than 6,000 in Eastern Visayas. Within the day, however, it weakened until it became a tropical storm.

Mariners of small seacrafts are advised to take precautionary measures when venturing out to sea. Inexperienced mariners should avoid navigating in these conditions.
Meanwhile, PAGASA forecasts the center of Tropical Storm “SIONY” to continue moving west-northwestward and will become almost stationary this evening through Tuesday evening.
“Afterwards, “SIONY” will begin tracking west-southwestward or westward towards Extreme Northern Luzon. Due to the projected erratic movement of this system in the next 48 hours, there is high degree of uncertainty in the forecast track.”
