On several occasions in PEN, HKG, TPE etc I have held or even diverted because I was not happy to ATTEMP a landing in the wx. On one occasion in PEN another A/c ( SQ ) knew I was holding but chose to fly through the red returns on the radar and land!! amazing skill level that.
Now if your saying Thai ATC should improve their wx reporting skills or their ability to tell the Pilot's clearly ( in English ) what the wx is doing, then yes I agree it would help.
Also GROOVING of the Phuket runway must be done.
At the end of the day the Captain makes a decision. ( or not )
