The South West Monsoon Season during 2011 in Thailand was one of the worst in recorded history. Unlike the other events in the Top Five list that occurred during a few day period this one was due to a continuous rainfall over the course of several months. This led to nearly 13 million people effected with billions of dollars in damage to Northern Thailand ranging from Crops to overseas shipping making it the second costliest disaster in the World during 2011 behind the Tohoku Earthquake.
The rains in Thailand began to effect the area in March, but in July Tropical Storm Nock-Ten Made landfall over Vietnam and continued to push West towards Cambodia and then Thailand, this tipped the figurative and literal tipping bucket over causing flash floods across much of Northern Thailand.
By late September the flood waters approached the Capital City of Bangkok. The one fortunate situation with floods was in fact how persistent they were, thus providing time for levees and measures to be put in place to at least spare the downtown district of the city. A few instances came close to putting maximum pressure on the levees yet as the North East Monsoon Set in the rains began to settle reducing the stress on the city.
Monsoon Set in the rains began to settle reducing the stress on the city.
In the end millions were effected yet 790 people lost their lives officially, this does not take in account though the deaths possibly caused by disease or even stress directly related to the floods. This event defiantly deserves its place to be ranked within the Top 5 Weather Events of 2011.
