Tropical Storm Sandy is threatening to bring more rain to the East Coast and Alaska as the region braces for more storm surges.
The National Hurricane Center on Wednesday reported that Sandy was moving north-northwest at 3 mph, moving west-north-west at 10 mph and strengthening to a Category 3 hurricane by the end of the day.
As a Category 4 storm, Sandy would be the fourth hurricane to make landfall on the East coast since 1900, the last one to hit the region since 1998.
Hurricane Sandy’s track means it is expected to bring heavy rains to the West Coast and the East as it approaches the Great Lakes region, said Matt Ostrovsky, a hurricane expert at the National Hurricane Centre.
“This storm is going to be a very large storm, and its a big hurricane,” he said.
Sandy’s track will leave a trail of destruction in its wake, with heavy rains, flash flooding and power outages in parts of the Northeast and coastal areas in the Carolinas and South Carolina.
A powerful storm surge is expected along the East and Gulf coasts as Sandy makes landfall, and there is also the potential for flash flooding, with some coastal communities near New York City and New Jersey experiencing flooding.
Forecasters expect Sandy to move inland and reach the East Atlantic Coast around midnight ET.
Snow is expected in the Northeast, with the first snow on the ground in parts and scattered flakes of snow in others.
Sandy has the potential to bring up to 5 inches of snow on some parts of New England, with up to 1 inch in some places.
There will be significant power outage and disruption for parts of Maine, the only other major U.S. state in the path of Sandy, and parts of Pennsylvania, New Jersey and New York.
By late Thursday, a strong wind gust of up to 45 mph was expected to blow across parts of Massachusetts, and gusts of 60 mph and up were possible in parts to New York and New Hampshire, with wind gusts reaching 60 mph.
In the New England area, where some areas are expected to experience snow, the storm is expected move northeast-northeast over the area Thursday morning and move into New England late afternoon.
Heavy snow is expected late Thursday into early Friday, with scattered accumulations of up a foot or more and potentially up to three inches of rain.
Tropically-Moderate Storm Warning: Heavy Snow Possible In New York State As of Thursday morning, there is a severe thunderstorm watch in New York, with storm-force winds of 50 mph or higher expected with possible gusts up to 90 mph and isolated flash flooding with possible damaging power outfalls.
NWS Storm Prediction Center forecasters say that the storm could bring up a few inches of precipitation.
Storms of this type can cause significant power disruptions and severe damage to power lines, power substations, transmission lines, telephone poles, utility poles, power distribution and lighting.
According to a Weather Channel video of the storm, the eye of Sandy is expected the westernmost of two bands that may develop across New York Harbor.
Rainfall amounts could be up to 4 inches in parts, with potentially as much as 6 inches possible across the East River in some areas.
Weather.com meteorologist Paul Jaffe said the storm will likely bring more than the expected amount of rainfall to the east coast, with winds up to 75 mph possible.
Overnight, the National Weather Service issued a tropical storm watch for the eastern U.M.S., the eastern coast of the Upper Midwest, and the Northeast from the southern tip of Pennsylvania to the southern edge of New York state.
It is expected that winds could reach 50 mph and gusty rainfall.
