According to the September 19 storm forecast of the Vietnam National Center for Hydro-Meteorological Forecasting, early on the morning of September 19, the tropical depression in the northeastern area of Hoang Sa archipelago strengthened into a storm, storm number 4 in 2024.
At 4:00 a.m. on September 19, the center of storm No. 4 was at approximately 17.3 degrees north latitude; 109.8 degrees east longitude, 210 km northeast of Da Nang, and approximately 260 km east of Quang Tri. The strongest wind near the center of the storm was level 8 (62-74 km/h), gusting to level 10; moving mainly westward at a speed of approximately 20 km/h.
Previously, on September 18, the Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA) said that the tropical depression that the Philippines calls Gener has left the Philippine forecast area (PAR) into the East Sea, expected to strengthen into a storm on September 19 with a level 8 intensity, gusting to level 10.
At 4:00 p.m. on September 19, the center of storm No. 4 was at about 17.2 degrees north latitude, 107.2 degrees east longitude, in the coastal waters from Quang Tri to Quang Nam.
Level 3 natural disaster risk in the western sea area of the North East Sea (including the Hoang Sa archipelago); the sea area from Nghe An to Quang Ngai (including Ly Son island, Cu Lao Cham, Con Co, Hon Ngu); the mainland area from Ha Tinh to Quang Nam.
PAGASA's latest storm bulletin on September 19 said that there is currently no depression or storm in the Philippines' PAR forecast area, after both Gener and storm Helen (international name Pulasan) have left PAR.
However, PAGASA forecasts that during the week of September 18-24, a new low pressure area is expected to form northwest of PAR, with the possibility of strengthening from low to moderate.
During the week of September 25 to October 1, the new low pressure is expected to leave PAR and move southwest towards China. However, this week another low pressure will continue to appear in the north of PAR, with the possibility of strengthening from low to moderate.
Thus, in the 2 weeks from September 18 to October 1, the Philippines continuously faces the risk of new low pressure appearing.
