Via Illinois State Climatologist Jim Angel, Australia's weather service has observed a growing ENSO event that has implications for the U.S.:
It is now likely (estimated at a greater than 70% chance) that an El Niño will develop during the southern hemisphere winter. Although the El Niño–Southern Oscillation (ENSO) is currently neutral, surface and sub-surface ocean temperatures have warmed considerably in recent weeks, consistent with a state of rapid transition. International climate models surveyed by the Bureau indicate continued warming of the central Pacific Ocean in coming months. Most models predict sea surface temperatures will reach El Niño thresholds during the coming winter season.
Accuweather says not to worry:
While El Niño will not have an impact on this spring and summer's severe weather, it may come on early enough and strong enough to have impact on the upcoming hurricane season in the Atlantic and Eastern Pacific.
Disruptive winds, known as wind shear, often develop off the Atlantic coast of the United States and sweep over a large part of the basin during El Niño.
The greatest effects on the weather pattern in the Lower 48 states, including California, occur during the cold season.
El Niño winters are noted for wet and stormy conditions in the South and less-frequent, less-severe cold episodes in the Northern states.
There is a tendency toward dry conditions in the Northwest and North Central states during an El Niño winter.
A nice, warm, dry winter next year would be super. Here's hoping.
