Torrential rains of 40+ inches deluge Thailand
Posted by: Dr. Jeff Masters, 04:47 PM GMT del 31 Marzo 2011 +3
Torrential rains in excess of 40 inches (1.016 meters) deluged Thailand's Malay Peninsula this week, triggering floods that have killed at least 17 people. The floods submerged 61 major highways, affected 840,000 people, and forced the helicopter rescue of thousands of stranded tourists. Late March is usually a fairly dry time of year for Thailand, but near-record cold air settled in over the region this week, dropping temperatures to 5 - 10°C (9 - 18°F) below average. Heavy storms accompanied the cold air, and downpours with rainfall rates of up to 2 inches/hour affected the region for many days in a row. Sea surface temperatures of the waters surrounding the flood regions were near average, but were plenty warm enough to supply copious moisture to feed the storms. Flood recovery will slowed by additional moderately heavy rains of 3 - 5 inches expected to fall over the flooded region during the next week, according to the latest precipitation forecast from the GFS model.


Figure 1. The Multisatellite Precipitation Analysis (TMPA) analysis above was made using data that were calibrated using data from NASA's TRMM satellite. This analysis shows that rainfall for the past week over the Malay Peninsula was particularly extreme with totals of almost 1200 mm (~47 inches). TRMM satellite data revealed that rainfall in that area was frequently falling at a rate of over 50 mm/hr (~2 inches/hr). Image credit: NASA.

Incredible rainfall. Again....

It does appear that we are seeing more events like this recently, and based on projections by many Climate Scientists we will continue to do so for a while.....

Severe weather tore across central Florida on Thursday, trapping about 70 people at an airport in Lakeland, and spawning an apparent tornado in Tampa, the National Weather Service said.

Approximately 70 people were reported trapped in a collapsed building at the Sun 'n' Fun Aviation Fair at the Lakeland Linder Regional Airport in Florida due to severe winds, the weather service said.

I cancelled all of our Seminole elementary after school sessions today; hope I was right because what a pain in the neck!
Try contacting 150 parents during the day about changing after school arrangments. This is almost impossible so we are having to keep some, but not all of them. Looks like most of the wicked stuff is remaining south of Sanford/Altamonte area at this point.
good grief. Makes me wish I had just let it all go as planned! But I was not willing to drive over there and if I did not want to be on the road I didn't want to expect anyone else to be. Too bad the TEPCO managers don't feel the same way, huh?!

I know that these storms have been severe and deadly, but Florida has them all the time. It is just that in the past few years,we haven't seen many outbreaks like this. Anyone who has been here for many, many years know that they are not only uncommon, but usually very severe. Years ago, they were much worse.

Hello Gro...I typed a similar post to Jedkins a couple days ago. There has been a lull with severe weather down there...Severe weather happened more frequently in the 70,s and 80,s than in the 90,s and 2000,s...Not counting hurricanes...LOL

reed.... seriously?

some well-forecasted severe thunderstorms over one US state is more important than 40" of rain over a localized area in another country?

Some things are more significant than what is happening around you.

Indeed.
And here too.
While not causing any death or destruction, this Dry Season has been particularly wet, as forecast due to Nino/nina.

Now, the forecasts are calling for 60% more rainfall than average for Jun Jul Aug. Cannot remember where I that statistic came from originally, but someone posted it on here some weeks ago. And I appreciate that it's a long-term forecast...)

In any case, 'Severe Weather' seems to be more regular than before, whether it is extreme cold, extreme heat, extreme rainfall etc.
This is all well and good for us folk that like to look at/study weather, but for the people affected, it is Dread.
