NEW YORK — Thousands of customers in New York were without power Friday morning after a fast-moving storm that authorities blamed for at least one death.

“We have restored about 12,000 outages, and we are hoping to restore the rest by the weekend. We have crews working out there right now,” said Con Edison spokeswoman Elizabeth Clark, but 25,000 customers remained without power.

Most of them were in Queens, she said.

Crews in New York City worked overnight to clean up damage left behind by the storm’s strong winds and torrential rains, Mayor Michael Bloomberg said.

“There have been reports of damage to school buildings. We do expect all schools to be open tomorrow, but we’ll just, as the night goes on, make sure that everything is safe,” Mayor Michael Bloomberg said late Thursday.

A 30-year-old woman was killed in Queens, New York when a tree fell on the car she was driving, the New York Police Department said.

Surveyors for the National Weather Service will meet with New York authorities later Friday to analyze the storm and determine whether a tornado tore through the city, meteorologist Peter Wichrowski said.

“The good news is that most people were safe, just annoyed, traffic being bad or a tree coming down in their yard,” Bloomberg said Thursday.

All Long Island Railroad service going east out of Manhattan was suspended after the storm, as was service on certain subway lines running from Manhattan into Queens and Brooklyn.

Long Island Railroad spokeswoman Jennifer Uihlein said Friday morning that service on the railroad’s Port Washington branch remained canceled, and more cancellations and delays were expected coming into Penn Station.

“We are going to try to run as close to a normal rush hour as possible,” she said.

On Friday, the Federal Aviation Administration’s website said arrival and departure delays were at 15 minutes or less in area airports — which experienced significant delays as the storm raged Thursday.

Storm damage extended beyond New York City.

Public Service Electric and Gas spokeswoman Deann Muzikar said 5,500 customers were without power in central and southern New York. The utility hopes to have service restored by Friday afternoon, she said.
