"Snow is coming down pretty hard. It is going to stick and it is going to change over," said meteorologist Dan Hofmann, at the weather service's Upton office. "The intensity of the snow is a little heavier. It's not only sticking on the grass, but it is sticking on the roads."
Queens has already seen as much as an inch of accumulation on the ground, Hofmann said.
The switch over from snow to sleet, then rain is expected to take place between 9 and 10 p.m., said Hofmann.
A hazardous weather outlook -- alerting the public that conditions are right for bad weather -- is in effect for all parts of Long Island, along with most of the metropolitan area, the weather service said.
"Most likely, the rain will last through Tuesday morning and into early afternoon Tuesday," Hofmann said.
