El Nino is back.

US government scientists are saying that the periodic warming of water in the tropical Pacific Ocean, otherwise known as El Nino, which can affect weather all over the world, is back!

The Pacific was in a neutral state, however, forecasters at the National Oceanic and Atmospheric Administration say the sea surface temps are up about 1 degree C above normal. NOAA’s Climate Prediction Center also said temperatures in other tropical regions are also above normal. The readings are warmer than usual as much as 975 feet below the ocean surface.

When El Nino conditions are around increased rainfall across the east-central and eastern Pacific happens and with drier than normal conditions happen over northern Australia, Indonesia and the Philippines.

Additionally, a summer El Nino can cause wetter than normal conditions in the intermountain regions of the United States as well as over central Chile. There also tends to be more Eastern Pacific hurricanes and fewer Atlantic hurricanes.

“Advanced climate science allows us to alert industries, governments and emergency managers about the weather conditions El Nino may bring so these can be factored into decision-making and ultimately protect life, property and the economy,” NOAA Administrator Jane Lubchenco said in a statement.

El Nino can increase winter storms in California and storminess across the southern United States.

Then there is the possibility of a reduction in the seafood catch off the West Coast. Fewer fish affects food sources for birds and marine mammals.
