The latest storm information from the Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA) on November 17 said that experts from this agency have not detected any new storms threatening the country in the next 3 to 5 days.
PAGASA expert Daniel James Villamil said that the four weather systems - easterly wind, tropical convergence zone (ITCZ), wind shear and northeast monsoon (or amihan) will have a major impact in the Philippines.
The tropical convergence zone is a hypothetical path in which winds from the northern and southern hemispheres meet, affecting the weather in Mindanao and Palawan. Cloudy weather, scattered rain and thunderstorms are forecast for the next 24 hours in this area.
Meanwhile, Cagayan and Isabela recorded similar weather patterns, scattered showers and thunderstorms due to wind shear, where hot air and cold air converged.
The northeast monsoon is forecast to bring scattered light rains to Ilocos, Cordillera and other parts of the Cagayan Valley.
The Philippine weather forecast agency said that the easterly winds - winds blowing through the Pacific Ocean, bringing moisture and warm heat, will affect the Manila urban area and the rest of the Philippines. These areas are cloudy, gloomy, with scattered showers or thunderstorms.
On November 15, after information spread on Philippine social networks about Typhoon Verbena expected to make landfall in the Philippines in November, PAGASA confirmed that it is forecast to have no storms or tropical depressions making landfall in the country in the near future.
According to PAGASA's storm and low pressure forecast on the same day, a new low pressure may form near the Philippines during the week of November 21 to November 27. The new low pressure is likely to make landfall in Mindanao, Visayas and Southern Luzon in the Philippines before entering the East Sea and is unlikely to strengthen into a storm or tropical depression.
