SEVERE WEATHER BULLETIN #2FOR: TYPHOON "#RollyPH" (GONI)TROPICAL CYCLONE: ALERT

SEVERE WEATHER BULLETIN #2
FOR: TYPHOON "#RollyPH" (GONI)
TROPICAL CYCLONE: ALERT
ISSUED AT 11:00 AM, 30 October 2020
(Valid for broadcast until the next bulletin to be issued at 5 PM today)
"ROLLY" CONTINUES TO INTENSIFY WHILE MOVING WESTWARD OVER THE PHILIPPINE SEA.

Track and intensity outlook:
• Track: “ROLLY” is forecast to move west-southwestward this afternoon until Saturday evening. Afterwards, the typhoon will turn west-northwestward as it moves over the sea off the coast of Bicol Region towards the eastern coast of Aurora-Quezon area. On the forecast track, the center of the eye of “ROLLY” is likely to make landfall over the Aurora-Quezon area on Sunday evening or Monday early morning.
• Intensity: The typhoon is forecast to continuously intensify over the Philippine Sea and is likely to make landfall at peak intensity of 175-185 km/h.

Hazards affecting land areas:
• Rainfall: Today, the  trough of the typhoon will bring light to moderate with at times heavy rains over Bicol Region, Visayas, Caraga, Northern Mindanao, and Zamboanga Peninsula. The typhoon will likely bring heavy to intense rains over Northern and Central Luzon and Bicol Region, especially those areas along the track of "ROLLY", beginning on Saturday or Sunday.
• Strong winds: No locality is currently under Tropical Cyclone Wind Signal (TCWS) #1. However, in anticipation of the arrival of strong breeze to near-gale conditions due to “ROLLY”, TCWS #1 may be raised over several provinces in the Bicol Region this afternoon. Given that it is likely for this typhoon to continue intensifying prior to landfall, the highest possible TCWS that will be raised throughout the passage of this typhoon will be TCWS #3 or #4 (associated with destructive to very destructive typhoon-force winds).

Hazards affecting coastal waters:
• Rough to very rough seas (2.8 to 4.5 m) will be experienced over the seaboards of Northern Luzon and the eastern seaboards of Central and Southern Luzon. A Gale Warning is in effect for these waters. As such, sea travel is risky over these areas, especially for mariners of small seacrafts.
• Moderate to rough seas (1.2 to 2.5 m) will be experienced over the eastern seaboards of Visayas and Mindanao and the remaining seaboards of Luzon. Mariners of small seacrafts are advised to take precautionary measures when venturing out to sea. Inexperienced mariners should avoid navigating in these conditions.

Other tropical systems being monitored:
•  At 10:00 AM today, the Tropical Storm "ATSANI" outside PAR was estimated at 2,150 km East of Mindanao (10.5ºN, 145.1ºE). It has maximum sustained winds of 65 km/h near the center and gustiness of up to 80 km/h. It is moving west-northwestward at 35 km/h. Based on all available meteorological data, this tropical cyclone is likely to enter the PAR on Sunday or Monday. However, it is less likely to bring severe weather over any locality of the country over the next 3 days. Once inside the PAR, “ATSANI” will be assigned the local name “SIONY”.
