Northeast braces for 2nd storm in a week as other countries endure extreme weather

The U.K. had a deep freeze.

— -- The Northeast is bracing for its second winter storm in a week after one that hit Friday caused the deaths of at least nine people and left hundreds of thousands without power.

The next winter blast in the Northeast U.S. is expected to strike Tuesday night as a storm from the Midwest moves in, with a winter storm watch in place for much of the Northeast from Pennsylvania to Maine.

In fact, 20 states from Montana to Maine are under winter storm alerts, which means that 50 million Americans are in the path of heavy snow and strong winds conditions today through Wednesday.

The storm developing in the Midwest is expected to meet a coastal low, which will form off the Mid-Atlantic and move up the coast bringing snow and rain, and may help form a nor'easter over the East Coast when they meet on Wednesday.

Snowfall of 5 to 9 inches is forecasted for some places in the Northeast, with up to a foot in isolated areas.

The winter storm watch follows a nor’easter that pummeled the East Coast Friday, but this potential nor’easter is not expected to bring as much coastal flooding and wind as the weekend's storm.

Australia

Almost exactly on the other side of the world, Australia is still experiencing hot temperatures after near record-breaking highs in January that sent beachgoers scrambling for shade and water.

According to the Australian government's Bureau of Meteorology, Perth, a large city on the Western coast of the continent, may experience highs of 36 degrees Celsius, or 96 degrees Fahrenheit, on Tuesday and 32 degrees Celsius, or 92 degrees Fahrenheit, on Wednesday.

During January's heat wave, the temperature in Sydney hit an almost 80-year high of just over 47 degrees Celsius, or 117 degrees Fahrenheit.

Europe

Ten severe weather warnings were issued in the U.K. with travel warnings, cancellations of flights and trains, and closures of numerous roads and thousands of schools.

Heavy snowfall left residents across Europe trudging through the deep snow over the weekend, but even before the latest weather system, the U.K. had been attempting to recover from "the beast from the east," the nickname for a severe storm that struck the country last Wednesday.

According to the U.K.'s weather office, an alert was issued last week for Scotland warned that there would be heavy snow and strong winds that would be threatening and disruptive to life.
