Blizzards are expected in New England as early as December, while the rest of the country should expect a snowy winter. Residents should bring shovels because the biggest snowfall may start this month and last into December in waves.

Winter is when El Nino hits hardest. Idaho, Oregon, and Washington have milder, drier fall and winters. The event can also increase Alaskan rainfall, especially in the Gulf of Alaska.
However, US Department of Agriculture meteorologists say El Nino simply raises the possibility of certain weather patterns, so they're not assured.The El Nino can also impact agriculture.
Dry spells, wildfires, diminished marine productivity and salmon populations, and shoreline erosion are prevalent in Washington and Oregon during the warming phase.
