MANILA, Philippines: The combined effects of the low pressure area (LPA), formerly Tropical Depression “Kabayan,” and shear line area are currently impacting Visayas, Mindanao, and the Bicol Region, according to the state-run weather agency. Weather specialist Robert Badrina, from the Philippine Atmospheric Geophysical and Astronomical Services Administration (Pagasa), mentioned that while the LPA has a slim chance of redeveloping into a tropical depression, it is expected to bring rainfall along with the shear line in various areas.
These weather disturbances are projected to affect not only Visayas and Mindanao but also Mimaropa (Mindoro, Marinduque, Romblon, and Palawan), Quezon, and Aurora. Over the next few days, the LPA will change its direction and have a particular impact on Palawan.
Meanwhile, the northeast monsoon is causing overcast skies with rains over Cagayan Valley and Cordillera Administrative Region within the next 24 hours, as reported by the state-run weather agency.
The same weather system is also influencing Metro Manila and the rest of Luzon. In these areas, expect partly cloudy to cloudy skies with isolated light rains, according to Pagasa.
Understanding the Impact of LPA and Shear Line
The combination of the LPA and the shear line is causing weather disturbances in various parts of the Philippines. Let’s take a closer look at what these terms mean and how they affect the affected regions.
Low Pressure Area (LPA)
A low pressure area, or LPA, is an atmospheric condition characterized by lower pressure compared to its surrounding areas. It is often associated with clouds, rainfall, and possible thunderstorms. LPAs can develop into tropical depressions, storms, or typhoons under favorable conditions.
In this case, the LPA, formerly known as Tropical Depression “Kabayan,” has a slim chance of redeveloping into a tropical depression. However, it is still capable of bringing significant rainfall to the affected regions, particularly in Visayas, Mindanao, Mimaropa, Quezon, Aurora, and Palawan.
Shear Line
A shear line refers to a boundary between two air masses with different characteristics, such as temperature, humidity, or wind direction. When a shear line interacts with other weather systems, it can enhance cloud formation and precipitation, leading to heavy rainfall in certain areas.
In this situation, the shear line is amplifying the effects of the LPA, resulting in widespread rainfall across Visayas, Mindanao, Mimaropa, Quezon, Aurora, and Palawan.
Localized Impacts and Precautions
It is crucial for residents and visitors in the affected areas to stay informed and take necessary precautions to ensure their safety. Here are some localized impacts and precautions to consider:
Visayas and Mindanao
Due to the combined effects of the LPA and shear line, expect heavy rainfall in many areas of Visayas and Mindanao. This can lead to possible flooding, landslides, and disrupted transportation. Stay updated with the latest weather advisories and follow the instructions of local authorities. Avoid crossing flooded areas and take necessary measures to protect your property.
Mimaropa, Quezon, Aurora, and Palawan
These areas are also expected to experience significant rainfall due to the LPA and shear line. Monitor weather updates and be prepared for possible flooding and landslides. Take necessary precautions to ensure your safety and follow any evacuation orders issued by local authorities.
Cagayan Valley and Cordillera Administrative Region
The northeast monsoon is causing overcast skies and rains in Cagayan Valley and Cordillera Administrative Region. While the rainfall may not be as heavy as in other areas, remain cautious on the roads as it may still cause slippery conditions. Stay updated with weather bulletins and adhere to any advisories from local authorities.
Metro Manila and the Rest of Luzon
Partly cloudy to cloudy skies with isolated light rains are expected in Metro Manila and the rest of Luzon. While the rainfall is not significant, it is still advisable to stay informed about any changes in the weather conditions. Be prepared for sudden showers and take necessary precautions when traveling.
Conclusion
The combination of the low pressure area (LPA) and shear line is currently affecting various regions in the Philippines, particularly Visayas, Mindanao, Mimaropa, Quezon, Aurora, and Palawan. These weather disturbances can bring heavy rainfall, leading to possible flooding and landslides. Stay informed, follow local authorities’ instructions, and take necessary precautions to ensure your safety during these weather conditions.
