Climate experts are now all but certain this year will see the strongest ever El Nino develop in waters around the Equator with serious consequences for the UK.
When the phenomenon was announced earlier this year forecasters hoped it would fizzle out before winter.
But temperatures in the Pacific Ocean have been rising steadily and the most powerful El Nino on record is expected to be confirmed within days.
The knock-on effects around the globe, which include unusually cold winters in Britain, could be catastrophic.
The last El Nino, six years ago, saw the UK crippled by the worst winter for decades with widespread harsh frosts, sub-zero temperatures and heavy snow setting in from early December and lasting until March.
This year could top that killer winter which saw airports closed for days and led to the deaths of more than 25,000 people.
Warnings have been issued across the southern United States where the strength of El Nino is already causing worrying shifts in the jet stream.
This year's El Nino is set to affect weather patterns all over the worldClimate experts say the region is set for below average temperatures and above average precipitation which is likely to fall as snow.
It is a frightening reminder back to the winter of 2009 which saw both the US and Great Britain crippled by heavy snow and weeks of sub-zero temperatures.
El Nino that year is thought to have played a pivotal role in the Arctic conditions with the current conditions already looking much more powerful.

The El Nino is likely to bring severe weather across the Atlantic to Britain
The oceanographic anomaly is the result of a change in wind direction pulling warm waters away from Asia towards Peru and South America.
UK forecasters are also bracing themselves for the worst with all the ingredients in place for a lengthy and savagely cold and snowy season.
Climate scientists say it is still too early to know the full impact of the coming winter but agree a strong El Nino points towards severe weather.

James Madden, forecaster for Exacta Weather, said the winter outlook has worsened thanks to plunging Atlantic sea temperatures.
The Gulf stream, which pulls warm water from the eastern coast of the United States to the United Kingdom, has been rapidly declining, he added.
He said: “There will be a real chill at times in terms of temperatures due to below- average sea surface temperatures in the Atlantic and a virtually non-existent Gulf Stream.
“This is of some real significance to us in terms of future weather patterns and this is also likely to result in a much colder than average November with the first significant snow of the year in parts of the north for the UK.
“There will also be some snow to much lower levels of the country at times within this period, and even parts of the south of the UK could see some early snow before we enter December this year.
“December in itself may then follow on with a rather mixed theme of colder and milder interludes before an increase in severity of some exceptional cold and snow in the final part of the month and for prolonged periods throughout January and into February due to prolonged blocking patterns that will refuse to shift.
“The overall situation has also worsened in terms of much colder than average sea surface temperatures (SST) in the North Atlantic.”
