“When the tropical depression enters longitude 110-112 east longitude, that is when the depression intensifies and becomes a storm, of magnitude 9. If it continues moving inland, the storm will deviate slightly to the east. South. Due to the influence of cold air, it is due to the impact of this cold air that the storm tends to weaken “- said Mr. Lam.
Mr. Lam said that the development of the storms is quite complicated, the storms not only permanently move in a southwesterly direction, but on December 23 they tend to go west. At this point, the storm decreased in intensity to 7.
“Due to the influence of the typhoon, all areas of convection and rain clouds and strong winds will be located in the northwest of the depression / tropical storm. The sea area from Binh Dinh to Ninh Thuan will have very strong winds.
Even outside of level 8 strong storms, but in the coastal area from Binh Dinh to Ninh Thuan, there may be strong 9 grade winds. The cause of the strong winds is the combination with cold air, not quite the storm “- pointed out Mr. Lam.
According to Mr. Lam, when the storm enters Binh Thuan area towards Ca Mau, the intensity of the storm can reach level 7. At this time, the northeast monsoon is weakening, the topography of this area is diagonal in northeast-southwest direction. so the wind is not as strong as in Binh Dinh – Ninh Thuan.
Regarding the rain due to the influence of storms, Lam said, the rain will be mainly concentrated in the area from Da Nang to Binh Thuan, then the rain will spread to the entire southern region. However, according to Mr. Lam, the precipitation is not very large, only around 50 – 150 mm / hour.
“The most dangerous depression / tropical storm is strong winds, especially in Binh Dinh – Ninh Thuan area can reach level 8-9; Binh Thuan – Ca Mau with strong winds around level 7” – warned Mr. Lam .
