Torrential rains of 40+ inches deluge Thailand

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.

My question is, why in the world were they in a tent when such bad weather was possible?! Someone must have been following developments. If not, I hope next time they realize what folly it is to continue an outdoor event with these conditions.


I am not sure on that. Just one more thing to give my brother in law grief about. My intent is not to ridicule the situation, but when the SH... hits the fan, you just got to smile and keep on keeping on and good natured humor never hurts.

Might be "them doom casters never know what they are talking about, we can ignore them".

Brother in law was in this. Last week he was lording his trip to warm weather and such over the rest of us here in ND.

I noticed all the chatter and sent him a email asking him how that nice weather was working out for him. I did not know it was this bad when I sent the email. Follows his response.

On the link you sent. The little yellow airplane was the plane built by the kids that Lance was helping do the fund raising for. He just called. They had 600 lb weights on it & it flipped it through the air like a toy. Maybe some generous donor will come forward.


That's a Sad note..
Hope they find a Good Sponsor to help with this project.

I agree, this was a *HISTORIC* severe weather outbreak! Many that don't live here are not taking this serious at all, instead, mocking us and saying we're over hyping this event.


Sorry for those of you who have been affected by this event.

Momentous or significant might be a better term.

The mocking of those who continually predict dire situations when it is not warranted, is warranted.

Historic in Floridas terms, we never get over 50 reports of severe weather in one day, very rare. Tom Terry, a MET at Channel 9 news himself said that this was probably the worst outbreak of severe weather since the Superstorm dericho of 1993.

Maybe it should be termed "relatively historic, all things considered"..
That should satisfy everyone, although why the pre-occupation with the descriptive terms, I am not sure.

Now this was historic. I was directly involved with this incident as a EM of the County.

1998 Kissimmee tornado outbreak




From Wikipedia, the free encyclopedia


  (Redirected from Florida El Niño Outbreak)





The 1998 Central Florida tornado outbreak of February 22–23, 1998, was the deadliest tornado event in Florida
history. Forty-two people were killed and 260 were injured; seven
tornadoes were involved in the event. The previous record for the
highest tornado death toll in Florida history was 17 on March 31, 1962.
The first tornado of the outbreak came at around 11:40 pm in Lake County, Florida. Three were killed in this tornado. The most notable tornado of the night was an F3 that hit in Kissimmee, where twenty five were killed. Another F3 hit in Seminole County, Florida, near Sanford and Volusia County, Florida, killing 13. The last tornado of the night hit in Brevard County, Florida.



Correct. THAT is a historic event.

This is the other area of Thailand that I've been posting about for a few days now..

Situation Update No. 3
On 30.03.2011 at 07:57 GMT+2

At least 11 people are dead after flash floods swept through eight provinces in southern Thailand, officials said Wednesday. The flooding has affected more than 716,000 people, the country's disaster prevention agency said. Villagers in one province, Krabi, have been asked to take shelter at temples or other areas, said a local official, Sombat Morakot. "It rained severely in last couple of days," he said. "I have never seen something like this before. And when it rained, it flushed soil and logs down to villages." Surat Thani, the largest of the southern provinces, has received 855 mm (2.8 feet) of rain since Saturday. The area typically gets 51 mm (0.16 feet) of rain during a typical March.

here's some damage from the tornado not too far from me.

Looks like straight-line winds (hard to tell for sure without knowing if the wind was blowing and how hard at the time the pic was taken). Possible EF0, considering that mobile home parks tend to be tornado magnets.

Situation Update No. 2
On 31.03.2011 at 03:28 GMT+2

Severe flooding and mudslides in southern Thailand have killed 21 people, stranded thousands of tourists and threatened to delay shipments of rubber in the world's largest rubber-producing country, authorities said. Trains to the region have been cancelled and three airports have been shut, including one on the popular island of Koh Samui. As well as Koh Samui, foreign tourists have also been stuck at resorts in Krabi and Koh Phangan. The Thai navy evacuated about 1,200 people from Koh Samui and Koh Tao, a remote island popular with backpackers. Thailand's navy sent four vessels including an amphibious landing craft with on-board helicopters to deliver supplies and rescue tourists and villagers in areas severely hit. "More rain is expected in the next few days," Satit Wongnongtoey, a minister in the prime minister's office, told Reuters. British ambassador Asif Ahmad said Britain was in close contact with the Thai navy on the evacuation of tourists from the region.The flooding could delay shipments of between 1,000 and 1,500 tonnes of smoked rubber sheet, industry officials said. The region supplies 90 percent of the 3.2 million tonnes produced annually in Thailand, the world's biggest producer and exporter. "Small producers along the upper south, who need to carry rubber by road to be shipped from Bangkok's port are facing disruption as roads are cut off," Prapas Uernontat, secretary general of the Thai Rubber Association said. Nearly a million people have been affected by unseasonably heavy downpours across the region. Mudslides were reported in three areas in Krabi province. At least 10 people were killed in one village, with at least 10 others missing. Wiboon Sangruanpong, director-general of the Department of Disaster Prevention and Mitigation, said it was too soon to assess full damage and said more mudslides were possible. Along with the airport on Koh Samui, the Nakhon Si Thammarat and Surat Thani airports have also been shut.

I'm not sure I would consider this a historic outbreak, Tampa Bay METS said its been unusual to see this lately, but its still about a every by year event they said. The head meteorologists also said outbreaks like these were more common in the 80's and 90's but have been rare in the last 10 years or so.
Thats my point. Yes, the last couple of days have been a significant outbreak. But not something that should be considered "historic". IMO, if it happens more than once every 5-10 years, its not historic.

Another line of storms is getting stronger to my west, lots of loud thunder here again!

I don't think it could possibly be anything close to like I had earlier, but its still gonna bring another burst of very heavy rain and strong winds, probably 40 to 50 mph.

Important is a matter of where you are standing. If you are under these storms, I doubt Thailand is more important to you. Besides, how many bloggers do you think we have from Thailand?

Very few, but if we focused our attention only on what impacts the largest number of members on this blog, we would be speaking about Florida on 80% of the blog entries.

While these storms were severe (and I *never* intentionally tried to diminish that they were severe storms), I wouldn't consider them earth-shattering events worthy of panic. Yes, its absolutely necessary to hunker down. Yes, its absolutely necessary to warn others of the storm coming. But no, it is not necessary to repeat yourself several times, or go into a panic. Panic does not help ANYONE. When people act like the sky is falling (as some did yesterday and earlier today), I get a little irritated, since it can easily drown out or take attention from postings that convey more or different information that is useful.

Glad everyone made it through the storm OK. Hopefully the damage is minimal, and mostly cosmetic or easily repaired.

My gosh, I had this feeling today would break the streak of living here and not having a tornado hit... My weather station had gusts nearly 90 mph, the tornado came very close to here, I had to rush my mom and pets into the closet as the tornado approached, it never actually hit but it is a complete mess around here from powerful straight line winds. The tornado did some significant damage near by including toppling a radio tower and tearing through a nearby mobile home park. Its easy to say its "only an f0 or f1" until it hits your area....


Seriously for those of you who say people are hyping the severe weather in Florida. Grow up. This is a weather blog, not just a place to talk about your stupid politics, oil prices, and GW politics. Get over yourselves and leave people alone.

Just because some of us have a passion for ever doesn't mean you have to be like immature juveniles and try and ruin people's excitement. Nobody claimed its the end of the world for Florida, but this is a serious event.

Some of you people would have peed your pants if you were here, I'm still hit with shock. We also got incredible rainfall and my street is completely flooded.

That super cell that produced the tornado that came onshore in Indian rocks was the one that hit me. Not only was this the strongest winds we've ever had but the core of the cell dumped rain rate of 7.5 inches per hour and 2.75 inches here in just 10 minutes! My Street is flooded the worst Ive seen in 2 years.

By the way we just got power back after hours and I'm still shocked from what came through here so that's why it took me a while to reply. Thank God no severe structural failure or injuries have occurred around here. Just classic hurricane force wind gust damage.

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.

The World record rainfall for 1 minute is 1.23 inches at Unionville, MD, USA

By the way, the METS here said that tornado had a shear reading at 108 mph on radar, I still don't know exactly where it hit but Ive been hearing reports, I Didn't get hit by the tornado but it came close, it felt like a tornado with more than 80 mph gusts on my weather station...


Another line of strong storms has redeveloped and headed back at me, I was just taking about how Florida has had a severe weather lull for a while and hasn't experienced it as frequently like we did back in the 80's and 90's.

Maybe its turning back to more active severe weather? Its too early to call but if we start getting more of these events its probably a sign of a change in pattern.
