New York Today: Messy Commute

Justin Lane/European Pressphoto Agency

Good morning on this gloppy, nasty Monday. Got your boots, rubbers, galoshes?

Depending on your location, various things are falling from the sky â€" rain, sleet, snow.

Whatever they are, they’re making it a hassle to get around, and potentially dangerous.

Around the region, speed limits are reduced, trains are delayed and roads are slick.

There were 20-car pileups overnight, on the Bronx River Parkway in Yonkers and Route 95 in Greenwich. Some people were injured.

North and west of the city, many school systems are opting for a late opening.

In the city, it’s just rain, but on top of the half-inch or so of snow that fell last night, icy spots may remain.

The mercury climbs to the mid 40s by mid-afternoon. The rain should stop by then, too.

But on Tuesday, there will be one to three inches of snow in the city, more to the south.

After that comes the big chill: three days below freezing, with nighttime lows deep in the 20s.

Welcome to winter, people.

Here’s what else you need to know.

COMMUTE

Subways: Delays on the 4, 5 and F. Check latest status.

Rails: Check L.I.R.R., Metro-North or N.J. Transit status.

Roads: Speed limits cut to 25 miles an hour on the Goethals and Outerbridge crossings and 45 miles an hour on the New Jersey Turnpike. Check traffic map or radio report on the 1s.

Alternate-side parking is in effect all week.

AND FINALLY…

This week in 1909, something revolutionary appeared on an American moving-picture screen: color.

A British inventor demonstrated his new Kinemacolor system to skeptical crowds at Madison Square Garden.

The scenes paraded one after another: A vase of flowers. A woman mending nets on the Riviera. Turkish troops in Constantinople.

Then came the real test: a rainbow over a waterfall.

“It wasn’t a splash out of all the paint pots,” The Times marveled. “ It was an infinitely delicate commingling of colors â€" a rainbow!”

For an encore, a hippo yawned, “thereby revealing the red interior of his face.”
