no mention of La Niña or its affect?

La Niña is still a ways out into the future - and won't start affecting weather until well into the Autumn period.

According to the NOAA Center for Weather and Climate Prediction, most models suggest a transition to ENSO-neutral by May-June-July (MJJ) 2016 with the increasing possibility of La Niña conditions after June-July-August (JJA) 2016.

La Niña is the positive phase of the El Niño Southern Oscillation (ENSO) and is associated with heavy rains in Indonesia, the Philippines and Thailand. The last La Niña episode occurred between mid-2010 and early 2012 - this La Niña was a large factor in the 2011–2012 Thailand floods.

This is the updated forecast as of 25 April:

"The good news was revealed by the departments deputy director-general Mr Songkran Aksorn at the meeting of a committee responsible for solving the drought crisis."

Awesome job by the committee....whatever they're doing, just keep it up. It's really working.

By the end of May lets hope they have a plan B

Committee Responsible for solving the drought crisis Action Plan (CRAP):

  1. Wait.
  2. Change name to Committee Responsible for solving the flood crisis
  3. Prepare tugboats and rope
  4. Wait

How to interpret this chart?

Is the line or the bars more important?

Does that mean Thailand has increased risk of flooding due to a strong La Niña effect?

The bars represent the probability of a particular ENSO phase (El Niño/neutral/La Niña), so the chance of La Niña and ENSO-neutral are about equal by June-July-August, with La Niña favoured afterwards.

While La Niña is associated with heavy rains in Indonesia, the Philippines and Thailand, and the last La Niña episode was a large factor in the 2011–2012 Thailand floods, not all La Niña episodes cause flooding in Thailand.

What is concerning, is that in 2011, the monsoon started in May, and major flooding began as Tropical Storm Nock-ten hit around 31 July, which was exacerbated by heavy rains continuing longer than usual due to the effect of La Niña - and now we have two tropical storms forecast in August to September in conjunction with this La Niña...

So as bull <deleted> baffles brains.... What you're saying is that it might rain sometime soon, if not before?

As always, the rains will come and bring flooding after a drought.

And all of that flood water will head down the river to the gulf where it will become useless.

It is way past time Thailand built reservoirs to reclaim and retain all of that flood water for use in the dry season.

There is a lot of pretty useless farm land that could be converted to lakes to not only retain water for agriculture, but create recreation areas and higher valued land around the lakes.

It's not rocket surgery or brain science!

Sorry it's only available in German language but I think with translation understandable.

If floods do eventuate, and neither government learned any lessons from the 2011-2012 floods nor did anything the minimise the damage of any future flood disaster, whom do you suggest TV posters blame?

The bars represent the probability of a particular ENSO phase (El Niño/neutral/La Niña), so the chance of La Niña and ENSO-neutral are about equal by June-July-August, with La Niña favoured afterwards.

Apologies for my use of cited sources, technical terms and multi-syllabic words; next time I'll just make unsubstantiated claims using small words. Krub.

The brief storm in Bangkok yesterday proved to be quite fortuitous: it closed the giant Ferris wheel at Dinosaur Planet Park about 5 minutes before it burst into flames. The place has only been open about a month and already safety concerns. Front page BP.

But it might just annoy those people who own and live off that useless .farmland. Recreation opportunities and neighbouring land values won't feed their families!
