As the lower atmosphere becomes warmer, evaporation rates will increase, resulting in an increase in the amount of moisture circulating throughout the troposphere (lower atmosphere). An observed consequence of higher water vapor concentrations is the increased frequency of intense precipitation events… — NASA’s Earth Observatory

Just off the coasts of Colombia, Ecuador and Peru, the Pacific Ocean has been abnormally warm of-late. For the past month, sea surface temperatures have ranged between 3 and 5 degrees Celsius above average. This excess heating of the ocean surface, facilitated by human-forced climate change, has pumped a prodigious volume of moisture into the atmosphere of this coastal region. Southerly winds running along the western edge of South America have drawn this moisture north and eastward — feeding into the prevailing storms that originate on the Atlantic side of South America and track eastwards.
