18Z GFS is always such a tease. I want to believe but I know better without the ECMWF suite on board. And it actually was on board yesterday. But definitely not now.
Looks like El Nino is gone around Nino Region 3.4. Monday reading was +0.6C probably +0.4C now. I expect La Nina definitely to be in place by time we start August!!!.
