These last few days we have had some really heavy rain in the Bangkok area. This is due to a strong southwest monsoon over the Andaman Sea, Thailand and the Gulf of Thailand. It is expected to persist until at least Monday or Tuesday. I bought this rain gauge during my recent trip back to the UK and as you can see it wasn’t big enough for the overnight rain. I need to find another one but I have never seen them in Thailand.
As you can see from this picture tweeted tonight, there is again deep flooding around Bangkok. Some people tweeted that smaller roads were starting to be impassable for cars. Now, before you panic, this doesn’t mean a repeat of last year. The problem is that the drains cannot cope with this much downpour in such a short period. We hardly ever get heavy rain such as this. Once the rain stops most of the water will drain away within a few hours.
