On October 4, as Typhoon No. 11 Matmo was still moving at sea, the Philippine Meteorological Agency warned that a low pressure area outside the Philippine monitoring area (PAR) was likely to strengthen into a storm and enter the PAR early next week.
If it develops into a storm, the system will be named Quedan, becoming the 17th storm to enter the PAR in 2025 and the second in October.
According to an update from the Japan Meteorological Agency (JMA), there is a possibility that in the next 48 hours, this low pressure area (code 94W) is likely to strengthen into a tropical depression (it may strengthen earlier than initially expected). Environmental conditions are very favorable for low pressure 94W to continue to develop in the coming days.
In addition to the low pressure, meteorologists have also recorded another severe weather zone forming off the Pacific Ocean. It is likely that in the coming days, a new tropical depression will appear, increasing pressure on the Southeast Asian region.
The JMA's forecast is in line with the forecast of the Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA).
In the 2-week storm forecast bulletin, PAGASA said that during the week of October 3-9, in addition to storm Paolo ( Matmo), a low pressure area appeared inside the PAR, moving towards Northern Luzon, with the possibility of the low strengthening into a storm.
During the week of October 10-16, another low pressure will also appear in the PAR, expected to pass through Visayas and Luzon.
Forecast models still show unexpected changes that may occur in the development of these weather systems. Meteorological agencies recommend that people continue to closely monitor weather forecasts.
From the beginning of this year to October 4, there have been 11 storms in the East Sea - a storm season considered as unusually strong activities and extremely severe developments in the East Sea and mainland Vietnam.
