This weekend’s chilling gusts of wind and heavy snowfall may make for the largest winter storm the city has seen in years, and millions of straphangers relying on public transit may have to readjust travel plans. The MTA is warning New Yorkers they may face mass transit delays and cancellations across the city.

"I do not like the snow. I do not like the cold weather," said 6-line rider Sheila Dawes.

The Parkchester resident says the bone-chilling weather is enough to keep her inside. But she bundled up Thursday night, wearing a long puffy jacket as she braved the freezing temperature to gear up for the storm.

"What I'm planning to do is whatever I need, you know, milk, juice, and bread. So I won't have to go out," she said.

It may be smart to take Dawes' advice on this one— according to the MTA's website, 6-12 inches can lead to reduced service with express trains running local. In extreme weather conditions, some lines may not run at all, especially above ground where trains are vulnerable to the elements

Buses will be geared up with snow chains, but drivers may still have to brave whiteout conditions on the road, leading to route cancellations, skipped stops and longer wait times.

The MTA expected to announce its official winter storm plan Friday.
