We are closely monitoring two significant weather systems in the tropical Western Pacific. These areas of interest could have notable impacts on the region, especially for those in the Philippines, Vietnam, and Southern China. Let’s dive into the details.
System One: East of the Philippines
Our first area of concern lies to the east of the Philippines. This system shows potential for development and could make its way over the Visayas or parts of Luzon by the end of the week. The good news is there’s a lot of convection, meaning the energy in the atmosphere is widespread. This dispersion can make it difficult for the system to consolidate into a more powerful storm. However, the bad news is that this widespread convection can lead to significant rainfall, raising the risk of flooding.
Despite the system’s current disorganization, we can’t rule out the possibility of it tightening up just before landfall, which would increase the rainfall intensity across parts of the Visayas. We’ll keep a close watch on this as it progresses through the week.
System Two: West of Luzon
The second system is situated just to the west of Luzon and could develop into a large monsoonal gyre. This type of system is characterized by a broad, loosely organized circulation with extensive convective activity. Monsoonal gyres can be significant rainmakers, and this one is no exception.
Currently, we see convection trying to wrap up in the West Philippine Sea. By the weekend, this could result in a broad monsoonal gyre, potentially bringing heavy rainfall and strong winds as it moves towards Vietnam and Southern China.
Forecast Models and Projections
We rely on several forecasting models to predict these systems’ behavior. The European Centre for Medium-Range Weather Forecasts (ECMWF) and the Global Forecasting System (GFS) both indicate some form of development in these areas. The ECMWF model, for instance, shows broad circulations, while the GFS highlights a tighter circulation in the West Philippine Sea and a weaker system moving onshore into the southern Visayas and northeastern Mindanao.
Despite the variations, both models suggest increasing rainfall not only for the Philippines but also for Palau, Vietnam, and Hainan. Some areas could see well over 50 to 100 millimeters of total precipitation.
Regional Impacts and Precautions
Residents in the affected areas should prepare for heavy rainfall and potential flooding. The Philippines, in particular, should brace for increased rainfall from these two systems, which could exacerbate the ongoing rainy season’s effects. The additional moisture and instability could lead to localized flooding and landslides, especially in low-lying and mountainous regions.
In Vietnam and Southern China, the monsoonal gyre could bring significant rainfall and strong winds, impacting coastal and inland areas alike. It’s crucial to stay informed through official weather sources and heed any warnings or advisories issued by local authorities.
Additional Weather Insights
In addition to the tropical systems, we have the ongoing rainy season front affecting the northern regions. This front continues to bring rain through mid-July, adding to the overall wet conditions.
For those interested in celestial events, the International Space Station (ISS) will be making a pass over Manila on July 10th at 7:34 PM local time. Look towards the west to the north for a chance to spot it, weather permitting.
Final Thoughts
As we monitor these developing systems, it’s important to stay informed and prepared. While the 2024 typhoon season has been relatively quiet so far, these potential developments remind us of the importance of vigilance during this period. Ensure you get your information from official sources and take necessary precautions to protect yourself and your property.
