This El Niño winter may feature more than twice the normal amount of strong East Coast storms, with 19 forecast compared to a normal of 9 by ECMWF.

That's going to leave a mark, with more frequent risks for coastal and freshwater flooding, strong winds and inland snow.

The U.S. looks poised to get a real taste of stormy, El Niño-fueled weather into December.

The Madden-Julian Oscillation, a pulse of tropical thunderstorms that travels around the globe, will move across the Pacific and reinforce the already active pattern.

The ECMWF seasonal expects El Niño to peak in the central Pacific around the new year — and linger into June.

In the eastern Pacific, near Ecuador, Peru and Chile, twin El Niño peaks are predicted in November and May, with immense ocean heat lasting for at least six more months.

Marine heat waves have reached rare "beyond extreme" intensity levels near Southern California, Ecuador, Peru and northern Chile as El Niño's warmth spreads.

That's the highest level on this scale and represents a huge departure from typical conditions.
