Many villagers lost their valuables due to the rapid runoff.

Local officials said more than 1,000 rai of farmland in five villages in the subdistrict were also affected by floods.

At the Thai Meteorological Dept's website you can also look at various weather radar images from around the country. I think the "Radar Loop" images are particularly useful as they show rain/storm movement, intensity, etc....very useful to help determine if you have rain coming towards or going away from your location and the intensity of the rain. Keep in mind the images displayed are referenced to GMT time so you will need to add 7 hours to correct to Thailand time. The radar images are usually 15 to 30 minutes fresh...be sure to refresh the page every few minutes. For folks living in Bangkok and surrounding provinces the Suvarnabhumi Airport Radar Loop is probably the most useful.

Waterfalls in many provinces closed off due to heavy rains

BANGKOK, 1 September 2014 (NNT) – National park authorities have closed off public access to a number of waterfalls across the country due to increased risk of flooding during the rainy season.

Mae Ping National Park officials made known that the Koh Luang waterfall in Lamphun province has been closed as a result of continuous downpours to ensure safety for tourists. The popular spot has been shut down as a safety precaution since August 31.

Doi Inthanon National Park authorities in Chiang Mai province have also prevented access to Mae Klang waterfall in fear of flash floods and forest runoffs following a slew of heavy rains. Stricter surveillance has been ordered in nearby waterfalls. If the rains subside, visitors could be allowed to be back in the waterfall area in 2 days.

Other waterfalls in the province such as Mae Sa, Tad Mok and Mok Fah waterfalls have also been closed to the public on Sunday due to heavy rains.

The Meteorological Department has forecasted that widespread rains will remain over the upper parts of the country. Provinces such as Chiang Rai, Lampang and Sukhothai are urged to brace for more storms.

So what the heck,it is the rainy season,plan ahead for it.

Just curious if the runoff from all the rain and flooding will culminate in the Chao Phraya and more significantly, should BKK be on standby? From previous episodes, BKK is the point which water flowing out to the sea passes by. Weather specialists?

Up until the last couple of weeks, this has need the driest year over the last 5-6 years. With 2 months of the rainy season left to go, I wouldn't expect any major flooding in bkk. Just the typical flooded roads from downpours as we get every year.

Wow, very unusual - torrential rain during the raining season - WOW!!!!
