El Niño's comeback in 2017 ?

The "Niño Costero", a phenomenon linked to the warming of the eastern Pacific's waters along the coasts of South America, is the cause of the heavy rains and floods which have affected Northern Peru and Southern Ecuador since January 2017. For the time being, the phenomenon remains localized, but it is about to become the global El Niño phenomenon due to the rising temperatures of the central and western Pacific's waters.
While El Niño appears irregularly every 2 to 7 years, usually beginning in mid-year for a period of 6 to 18 months, its last occurrence was during the 2015/2016 season. This phenomenon reaches its maximum intensity towards Christmas: droughts develop in Indonesia and Australia, tropical storms and hurricanes appear much more to the east than usual, while the coasts of Peru receive unusual rainfalls causing floods and landslides.
During the El Niño episode in 2015/2016, severe droughts appeared in the Caribbean region, Colombia and Oceania by the end of 2015 and early 2016, followed by a period of intense rainfalls in the Caribbean and two major hurricanes: "Matthew", in October 2016, causing significant damage to Jamaica, the West Indies and Florida, and "Otto" in November 2016, that hit the South of Nicaragua and the North of Costa Rica.
