The rainy season is over.
Enter winter in Nov.
But many people are probably wondering why during this heavy rain.
and continued to fall for almost the whole week
especially in the evening
until many areas in Bangkok
There is flooding, not different from the rainy season.
For those who are waiting to experience the cold weather
I have to wait awkwardly because it's hot and humid, alternating with rain.
Or is the weather in Thailand already abnormal?
Let's see the answer from "Dr. Suthat Weesakul" Director of Hydro Informatics Institute
(Public Organization) or HII came out to admit that
It is not likely to rain during this period.
from air pressure from China
has spread to cover upper Thailand
But due to the low pressure cell from the Andaman Sea and the monsoon trough combined into 2 forces, the southeasterly winds are stronger.
It blows through the Gulf of Thailand and the South China Sea.
Until the humidity in Thailand is more than usual
Causing it to start raining more in every region
“A few days ago, it might not rain in every region because of two factors: the low pressure cell from the Andaman Sea and the monsoon trough are not strong enough, causing rain only in the central and northeastern regions. up and down in the south more because it induces the southeast wind and the east wind make it stronger.”
Therefore, during this period, it will still rain.
Long until next week on November 28-29 and after that from November 30 until December 2, the rain will begin to weaken.
As for the reason for the heavy rain in the early evening consecutively at the same time
Or fall around 19.30-20.00 because humidity cannot penetrate during the day
from the barrier of heat
Although the rain began to weaken in all regions.
But since November 30, there will be more rain in the southern region alone.
Which is worried that there will be a flood
Especially the Tapee River will overflow its banks, affecting the area.
Surat Thani Province
HII officers have now been sent to the area to assess the situation and hold daily meetings with relevant agencies.
in coordination with the PWA that
In which area will it rain?
“This morning, Nov. 26, the water began to overflow from the Tapee River. Because of the heavy rain in Surat Thani, about 90-120 mm, including Nakhon Si Thammarat, there is rain of 70 mm or more, and because the monsoon trough will increase from November 30, it will stay for another 1 month, causing a lot of rain to accumulate in South from Prachuap Khiri Khan, Chumphon down
Tapee River
Things to prepare for flooding in the South
More arrangements must be made to work with local authorities.
Try to connect the flood level with the road to the same level.
because the road standard reference level in the south
still not in line with the level of flood water
there must be a warning
Especially this year, I have to admit that it rains continuously and for a long time.
There is a chance to fall until the end of the year, focusing on the southern area.
Another question on many people's minds is why this year's cold weather is late.
or not feel the cold
because the wind is against the cold
which moves from the north to the south
In addition, the pressure patch is moving up and down.
But will be stronger during November 29 until December 2, causing cooler weather in the upper northern areas.
From the high pressure after November 30 and the pressure will be stronger until there is less rain.
“The temperature will not drop much, about 1-2 degrees Celsius, which makes this year's cold not continually. But it is not considered abnormal at all. Including the continuous heavy rain now It's not unusual"
