Post-Tropical Cyclone Sandy, a former hurricane, has made landfall along the coast of southern New Jersey state as of 8 p.m. EDT on Monday, said the US National Hurricane Center.

As of 8 p.m. ET, the National Hurricane Center's latest data showed the storm's maxim sustained winds were holding at about 130 kph and the storm was moving northwest at 37 kph.

Sandy, which has killed 69 people in the Caribbean, will meet up with cold fronts coming out of the northwest and a high pressure system from Greenland, fueling it with enough energy to be as powerful as, or even worse than the 1991 storm.

The combination superstorm could impact about 50 million people cutting in it path.

As the storm approaches, the East Coast is bracing for a repeat of the "perfect storm" of 1991, which came around Halloween that year and killed dozens of people.

Meteorologists have been using the term "Frankenstorm" to describe the havoc. Sandy, expected to make a landfall around Halloween, could affect hundreds of millions of people living along the East Coast.
