Based on the DOST – PAGASA Tropical Cyclone Bulletin No. 7 the Eastern Portion of Sorsogon (BARCELONA, GUBAT, PRIETO DIAZ) is now under Tropical Cyclone Wind Signal No. 2 and the rest of Sorsogon is remains under Tropical Cyclone Wind Signal No. 1. as of 5:00 PM 22 October 2024 for Tropical Storm KRISTINE
A Tropical Cyclone Wind Signal (TCWS) is a plain text warning to particular land area that may experience winds of at least strong breeze in strength on the Beaufort Scale (i.e., 39 km/h, 22 kt or higher) within at most 36 hours from the time the signal is put into effect during the passage of a tropical cyclone. A particular wind signal has an equivalent expected wind threat, length of time (in hours) before onset of expected wind threat, and potential impacts to the locality. The current TCWS system uses five (5) levels of wind signals that are numbered from 1 to 5, with a higher signal number associated with higher general wind strength and shorter warning lead time.
The current TCWS system has been in use since 23 March 2022 based on the adoption of best practices from other tropical cyclone warning centers and regionally-accepted operational standards, developments in objective forecast guidance, operational experiences and challenges encountered by typhoon forecasters, and feedback from end-users and stakeholders.
Tropical Cyclone Wind Signal #1
WIND THREAT: 39-61 km/h (22-33 kt, 10.8-17.1 m/s)
WARNING LEAD TIME: 36 hours
POTENTIAL IMPACTS:
House of poor construction (e.g., wood frame, bamboo, makeshift), old dilapidated structures, and other structures made of light materials will suffer minimal to minor damage.
Some banana and similar plants are tilted, while twigs of small trees may sway with the wind. Rice crops, especially those in flowering and ripening stages, may suffer some damage.
Minimal disruption to public transportation.
Tropical Cyclone Wind Signal #2
WIND THREAT: 62-88 km/h (34-47 kt, 17.2-24.4 m/s)
WARNING LEAD TIME: 24 hours
POTENTIAL IMPACTS:
Minor to moderate damage may occur to makeshift or old dilapidated structures, and other structures made of light materials. Houses of poor and average construction (e.g., unreinforced CHB/masonry, mixed timber-CHB) may receive minor roof damage.
Unsecures, exposed lightweight items may become projectiles which may cause additional damage.
Some electrical wires may be blown down, resulting in local power outages.
Minor to moderate disruption to public transportation.
Most banana and similar plants are tilted, with some stooped or downed. Some small trees blow over, with twigs and branches of frail trees broken. Considerable damage is likely to rice and other similar crops, especially those in flowering and ripening stages.
