Two Big Extra-Tropical Cyclones Coming: One To Japan On November 25, Another To Canada On November 21, 2014

The tropical cyclone season may be fading in the Pacific, Atlantic and Indian oceans (Southern hemisphere aside) but mid-latitude storms are coming. And they are going to be big, bad and powerful. One will hit Japan on November 25, another will come from the Pacific and slam into British Columbia on November 21, 2014.

Generally extra-tropical cyclones are not so powerful (There are exceptions) as their tropical cousins, but the one likely to hit Canada is going to be particularly nasty with a minimum pressure of 960-970 mb.

We deal with the Japan storm first. It will come as a low pressure from China, move over Korea, strengthening all the time. As it approaches Japan it will intensify further, the pressure being about 998 mb. Not a very big storm but will bring strong winds and rains to Japan on November 25, 2014.

THE BRITISH COLUMBIA STORM EXPECTED ON NOVEMBER 21, 2014

The other storm is going to be bigger. It will start off as an innocuous low pressure in the Pacific and then move towards the Bay of Alaska strengthening all the time. Make no mistake, this guy is going to be big and powerful. A central pressure of 970 mb. Ominous. It is going to cross the Canadian coast on November 21, 2014. British Columbia (And southern Alaska) are in for gale and heavy precipitation in a week.

Nuri Will Turn Into A Strong Extra Tropical Storm And Affect Aleutian Islands. Eastern US Will Feel "Nuri" Effect

Presently  a weakened Typhoon Nuri is barreling along the waters off Japan's coast. On Friday it will strengthen again in the Bering Sea and pass the waters off the US Aleutian Islands. A direct hit is not expected but western islands will be severely affected.

Post-Nuri will pass between Komandorskie Islands [Russia] and Attu Islands [US] on Friday, November 7, 2014,  as a powerful storm. The Komandorskie [Commander islands] are inhabited by only 600 people. The Attu-Kiska Islands are uninhabited.

The worry is that Nuri will approach the populated Pribilof Island on Sunday and start disintegrating there. This island will see very high waves and hurricane winds. Bristol Bay will see very rough weather.

Alaskan shores will witness a storm not seen in decades.

A weakened Nuri will gain energy from the Pacific drift and turn into a powerful storm again. The affects of these storm will be felt in eastern US. A cold wave with December-like temperatures is expected in New York in a few days.

VANCE WEAKENS

Meanwhile Tropical storm Vance has weakened into depression and will bring rainfall in Central Mexico around Mazatlan.
