The latest forecast issued by the Climate Prediction Center has upped the chances of seeing EL-Nino this year now at 61% with the favorable time period pointing towards the 3rd quarter (July-September). What does this mean to you? Well it all depends on where you’re living as EL-Nino has a wide array of impacts that are different everywhere around the globe. Here are a few...
