    LATEST STORY: Extraordinary Circumstances Needed for a Historic Storm


    Depending on the path of Sandy, now strengthening in the Caribbean, people along the East Coast during the week of Halloween could be looking a destructive storm or breathing a sigh of relief.

    Final destination scenarios for Sandy range from bypassing the East Coast to creating a nightmare for tens of millions of people from Norfolk, Va., to Philadelphia, New York City and Boston.

    Tropical Depression 18 formed in the central Caribbean during midday Monday and strengthened into Tropical Storm Sandy six hours later. Sandy became a hurricane Tuesday, prior to making it's first landfall east of Kingston, Jamaica.

    As a strong Category 2 hurricane, Sandy made landfall a second time early Thursday morning on the southeastern coast of Cuba just west of Santiago de Cuba. Reports from Santiago de Cuba at the time of landfall indicated sustained winds of 78 mph and gusts to 114 mph.

    The AccuWeather.com Hurricane Center is confident that Sandy will head northward through Thursday, spreading life-threatening flooding rain across Jamaica, Hispaniola, eastern Cuba and the Bahamas.

    How Sandy tracks Friday and beyond is dependent on several weather factors, which at this time are very complex. These scenarios range from a disruptive and destructive hybrid between a hurricane and powerful nor'easter to a miss and a simple change to cooler weather for the East Coast.

    The worst case scenario for the East Coast involves Sandy paralleling the coast from Florida to the Carolinas this weekend before being drawn inland over the mid-Atlantic or New England early next week.

    While the Southeast coast would face heavy rain, strong winds and rough surf, far more serious impacts await communities from Virginia to Maine if this solution pans out.

    Reminiscent of the "Perfect Storm" during the week of Halloween 1991, damaging winds and significant storm surge would unfold near and northeast of its center along the coast. Similar to the 1991 storm, these conditions could last for days.

    In addition, if the storm were to move inland, unlike the storm in 1991, torrential rain would blast the I-95 corridor and heavy, wet snow would evolve over part of the Appalachian Mountains on the system's western and southwestern flank.

    A powerful hybrid storm curving inland over the Northeast would bring major disruptions to travel, flooding, many downed trees and widespread power outages.
