Public Storm Warning Signal (PSWS) No. 1 is a type of weather alert system used by the Philippine Atmospheric, Geophysical, and Astronomical Services Administration (PAGASA) to inform the public about the possible impact of a tropical cyclone on a particular area.
PSWS No. 1 is the lowest level of the alert system and is raised when a tropical cyclone is expected to affect a locality within 36 hours, and the maximum sustained winds of the cyclone are between 30 and 60 kilometers per hour (kph).
When PSWS No. 1 is raised, the public should expect occasional rains and gusty winds. Those living in low-lying areas and near mountain slopes should take precautionary measures against possible flash floods and landslides.
It is important to note that PAGASA issues different Public Storm Warning Signals depending on the severity of the tropical cyclone. Higher signal numbers indicate more severe weather conditions, with PSWS No. 5 being the highest and indicating that a tropical cyclone with maximum sustained winds of more than 220 kph is expected to affect a locality within 12 hours.
Here are some frequently asked questions (FAQ) about Public Storm Warning Signal (PSWS) No. 1:
- What is PSWS No. 1?
PSWS No. 1 is the lowest level of the alert system used by PAGASA to inform the public about the possible impact of a tropical cyclone on a particular area. It is raised when a tropical cyclone is expected to affect a locality within 36 hours, and the maximum sustained winds of the cyclone are between 30 and 60 kph.
- What should the public expect when PSWS No. 1 is raised?
When PSWS No. 1 is raised, the public should expect occasional rains and gusty winds. Those living in low-lying areas and near mountain slopes should take precautionary measures against possible flash floods and landslides.
- What should I do when PSWS No. 1 is raised in my area?
When PSWS No. 1 is raised in your area, it is important to stay updated with weather advisories and bulletins from PAGASA. You should also secure loose objects that may be blown away by strong winds and make sure that your home is well-prepared for possible flooding or power outages.
- What are the other PSWS signals and what do they mean?
PAGASA issues different PSWS signals depending on the severity of the tropical cyclone. PSWS No. 2 is raised when the maximum sustained winds of the cyclone are between 61 and 120 kph, while PSWS No. 3 is raised when the maximum sustained winds of the cyclone are between 121 and 170 kph. PSWS No. 4 is raised when the maximum sustained winds of the cyclone are between 171 and 220 kph, and PSWS No. 5 is the highest level and is raised when a tropical cyclone with maximum sustained winds of more than 220 kph is expected to affect a locality within 12 hours.
- How can I stay safe during a tropical cyclone?
To stay safe during a tropical cyclone, it is important to follow the advice and instructions of local authorities, stay updated with weather advisories and bulletins, secure your home and belongings, and avoid going outside unless necessary. You should also prepare an emergency kit that includes food, water, first aid supplies, and other essentials that you may need during a power outage or evacuation
