Hurricane Sandy is churning off the East Coast and is expected to join up with two other weather systems to create a huge and problematic storm affecting 50 million people. Here's a snapshot of what is happening or expected, state by state.
UPDATE at 10:32 a.m.: The U.S. Coast Guard rescued 14 members of a crew forced to abandon a tall ship about 90 miles off the North Carolina coast and continued to search for two other crew members. The storm lashed barrier islands and rendered several homes and businesses nearly inaccessible.
The number of power outages increased quickly in a state where utilities' response to past weather-related failures has become a political issue. Connecticut Light & Power says hundreds of customers are without power. Gov. Dannel P. Malloy asked a task force to ensure fuel suppliers are fully stocked. Many residents along Long Island Sound heeded warnings and evacuated.
UPDATE at 10:32 a.m.: Dover Air Force Base has relocated some aircraft in anticipation of the storm, and the Federal Emergency Management Agency has requested that the base be used as a staging area for support and supplies. Some residents of low-lying areas of the base have been ordered to evacuate. Hundreds of people fled to shelters as rough surf pounded the coast. Water covered some roads.
Snow is expected in mountainous areas. A winter storm warning is in effect in Harlan, Letcher and Pike counties through Wednesday morning. Forecasters say snow could accumulate from 4 to 10 inches in high elevations and 1 to 3 inches in lower elevations.
Virtually all Maine public schools opened Monday but some were closing early before the heaviest rain and wind from Hurricane Sandy. State officials say the biggest concern is wind, which is expected to cause widespread power outages. The state's utilities say they have crews poised to deal with expected power outages, including some from Canada.
UPDATE at 10:36 a.m.: Hurricane Sandy inflicted considerable damage overnight to a large, iconic ocean pier in the Maryland beach resort of Ocean City. In mountainous western Maryland, a blizzard warning was issued for sections of Garrett County for Monday night into Tuesday morning.
Baltimore is opening six shelters; several city intersections are closed because of flooding threats. Early voting, which began Saturday and was to run through Thursday, was canceled for Monday.
UPDATE at 10:36 a.m.: The Massachusetts Bay Transportation Authority is shutting down all service at 2 p.m. Monday due to expected high winds from Sandy. Secretary of Transportation Richard Davey said the order affects all subway, bus and commuter rail service.
Utilities brought in crews from as far away as Texas and the Midwest to cope with anticipated power failures. Most schools and colleges have canceled classes. The Boston transit authority said it would continue to operate as long it was safe.
Gov. John Lynch declared a state of emergency Monday morning, giving him extra authority to deal with the storm. It also gives the state the opportunity to apply for federal disaster relief. Earlier, Lynch put 100 New Hampshire Guard soldiers on active duty, and utilities secured crews from Canada and a number of states.
Two shelters are being set up, and some schools have closed.
UPDATE: Atlantic City's public safety director said most of the city is flooded. Willie Glass said the damage will likely be worse than the storm of 1962. Fire officials in Pleasantville report at least two rescues from homes surrounded by water.
Sandy's center is expected to make landfall in New Jersey late Monday. By daybreak, thousands of homes and businesses were without electricity. Thousands of people evacuated low-lying areas, and many inland towns hit by flooding from storm Irene last year issued evacuation orders.
UPDATE at 10:40 a.m.: Gov. Andrew Cuomo announced that the Brooklyn-Battery Tunnel and Holland Tunnel will close at 2 p.m. Monday. Officials said the already were seeing water levels that mirrored Hurricane Irene a year earlier. About 375,000 people have been ordered to leave flood-prone zones in New York City. Officials opened 76 shelters in open in the city and several others in Hudson Valley.
Many residents left low-lying flood evacuation zones, and the subway system shut down Sunday night. A storm surge of 11 feet is possible, the highest of all coastal areas being hit by Sandy. The New York Stock Exchange and other U.S. financial markets shut down for at least the day. Thousands of flights were canceled at the city's major airports.
Residents of low-lying areas and along Lake Erie were told to watch for flooding; utilities are anticipating high winds that could blow down trees and poles. Snow is forecast in some areas.
Many schools are closed. Philadelphia shut down its mass transit system, and hundreds of flights were canceled at the city's airport. Dozens of people took shelter at evacuation centers. Thousands of members of the National Guard have been told to be ready for deployment.
UPDATE: Officials are concerned about wind driving water north up Narragansett Bay, which could create flooding in low-lying areas of the upper bay, including Providence, Warwick and Cranston. About 2,600 National Grid customers were without power, mostly in Barrington and other parts of Bristol County.
Snow is expected in higher elevations, where a freeze warning has been issued. High winds are expected in many areas.
Gov. Peter Shumlin declared a state of emergency to provide access to National Guard troops in a state still recovering from the devastating effects of the remnants of Hurricane Irene. Culverts and storm drainage basins in some spots have been cleared of debris.
UPDATE: About 4,800 customers lacked power, and a utility said as many as 1 million could ultimately lose electricity. Many residents of Chincoteague Island, popular with tourists, shrugged off the idea of evacuation.
The capital area's transit system shut down rail service for the first time since 2003, and the Smithsonian Institution closed for the day.
As much as 2 to 3 feet of snow was forecast in mountainous areas, and flooding was possible in some areas. Several shelters were put on standby, and power crews were mobilized to handle potential failures.
