Thailand braces for heavy rainfall and flash floods in 51 provinces

[webfact]

The Thai Meteorological Department (TMD) has issued a warning for 51 provinces, including Bangkok, forecasting heavy rainfall and advising caution against flash floods and forest runoffs.

 

Today, the Thai Meteorological Department predicts strong monsoons will sweep through the upper northern and northeastern regions, impacting the pressure systems over the northern South China Sea. The monsoon’s force, covering the Andaman Sea, southern regions, the Gulf of Thailand, central Thailand, and eastern Thailand, is expected to bring heavy rain across multiple areas, particularly in the north, east, and western parts of the south.

Residents in these regions are urged to be vigilant against severe rainfall and potential flash floods, especially those living in low-lying areas and near mountains.

 

The department’s 11th announcement warns of heavy rains tomorrow in 55 provinces. The seas in the upper Andaman and upper Gulf of Thailand will experience strong winds, with waves reaching 2 to 3 metres and exceeding 3 metres in thunderstorm areas.

In the lower Andaman Sea, waves will be around 2 metres, also higher in thunderstorm zones. Mariners in these areas should exercise caution and avoid sailing in stormy conditions. Small boats, particularly in the upper Andaman and upper Gulf of Thailand, are advised to stay ashore.

It has been Persistently raining on Koh Chang now for what seems like weeks, lets hope if there is a disaster in Thailand all the money has not been spent/used on the 10k hand out from the disaster fund.

My weekly Tuesday golf game was rained out this Tuesday. This is only the second or third time in around 20 years.

As it has been raining very heavily for at least the past 7 days, this would appear to be a tad late at this time?!

Rain in Thailand is warm. Thai neighbours often comment on my ignoring of light to moderate rain and cannot understand that as a Northern European I am used to icy rain and gales and find Thai rain and wind completely comfortable.

Hopefully, this evening, or throughout most of tomorrow, Chiang Mai will see Torrential Downpours.

As long as I have been here, I still have yet to see a heavy rain in Chiang Mai.

 

In Taiwan, for example, it was nothing to experience two meters of rain within 24 hours.

Of course, that only happens during a typhoon, and only if the progress of the passing typhoon slows to a crawl.

 

How many millimeters of rain is considered to be a very heavy and sustained rain in Chiang Mai?

 

Torrential rain is very good for breaking up the monotony, as long as the rain does not lead to excessive flooding.

 

a. Why do they never predict the amount of rainfall in Thailand?

b. Yes, they predict wave height in meters.

c. But, no prediction of rainfall in millimeters, according to geographical location.

d. In the US, when I was last there, the weather service would predict snow accumulation, for example  I am not asking for a snow accumulation prediction for cities in Thailand. However, a prediction of precipitation in millimeters of rain would be very much appreciated, I think.

Here in CM, it has just begun to rain in earnest.

This looks like an entire day of rain.

And I am looking forward to it.

Raining-in-Earnest is becoming a rarer event here, these days.

The rainy season is underway it seems...
