Áp thấp nhiệt đới ít có khả năng ảnh hưởng đến đất liền Nam Bộ | VTV24

Key Concepts:

• Áp thấp nhiệt đới (Tropical low pressure)
• Bão số 15 (Storm number 15)
• Biển Đông (East Sea)
• Nam Bộ (Southern Vietnam)
• Thành phố Hồ Chí Minh (Ho Chi Minh City)
• Hà Nội (Hanoi)
• Độ ẩm thấp (Low humidity)
• Viêm mũi dị ứng (Allergic rhinitis)
• Nước muối sinh lý (Saline solution)

Tropical Low Pressure and Storm 15 Impacts

1. Tropical Low Pressure System:

• Impact on Southern Vietnam: Experts predict that the tropical low pressure system in the south is unlikely to directly affect the mainland of the Southern region today.
• Movement and Intensity: This system is expected to move in a northeast direction, then deepen into the southern part of the East Sea. It may strengthen to a force of level 7, with gusts up to level 9.
• Sea Conditions: The southwestern waters of the southern East Sea are warned of increasing winds from level 6 to 7, with gusts up to level 9. Wave heights are predicted to be between 2.50 to 4 meters, indicating rough seas.

2. Storm Number 15:

• Slow Movement: Storm number 15 is currently moving slowly, at a speed of only 2 to 5 km/h.
• Directional Changes: Its path is characterized by changes: initially moving north, then turning west, and finally heading southwest. The storm is expected to weaken gradually.
• Extended Adverse Weather: Due to its slow movement, the storm's outer circulation (hoàng lưu) will continue to cause adverse weather conditions, strong winds, and high waves in the northwestern waters of the central East Sea and offshore areas from Gia Lai to Khanh Hoa for the next 3 to 4 days.

Weather Conditions on Land

1. Ho Chi Minh City:

• Morning to Afternoon: After a cool morning, sunshine has appeared, and temperatures are gradually increasing.
• Temperature Forecast: The highest temperature is predicted to reach 31°C in the early afternoon today.
• Atmospheric Conditions: A northeasterly wind is blowing, contributing to a very airy, cool, and pleasant atmosphere.

2. Hanoi:

• Afternoon Forecast: The capital is expected to have warm sunshine in the afternoon.
• Temperature Forecast: The highest temperature is predicted to be around 25°C.
• Humidity Alert: A significant concern is the persistent dry air, with the lowest humidity level recorded at only 43%.

Health Advisory: Dry Air and Allergic Rhinitis

• Consequences of Dry Air: Prolonged dry conditions can lead to dryness of the nasal and mucous membranes, making them susceptible to irritation. This can trigger allergic rhinitis, with symptoms such as sneezing, nasal congestion, and runny nose.
• Preventive Measures:
  • Nasal Hygiene: It is recommended to frequently spray and rinse the nose with saline solution. This helps to moisturize the nasal lining and remove dust and pollutants.
  • Mask Usage: Wearing a mask when going outdoors is also advised to protect against irritants.

Conclusion

The weather forecast indicates a tropical low pressure system unlikely to impact Southern Vietnam directly, but it will cause rough seas in the southern East Sea. Storm number 15's slow movement will prolong adverse weather in specific offshore areas. On land, Ho Chi Minh City will experience warm and pleasant conditions, while Hanoi will be sunny but with very dry air. The dry air in Hanoi poses a risk of allergic rhinitis, for which nasal hygiene with saline solution and mask-wearing are recommended preventive measures.
