The Long Island Rail Road is offering eight extra eastbound trains for people trying to get home before the next snowstorm.
The extra LIRR service will run from roughly 2 to 4 p.m. Wednesday.
The National Weather Service has issued a winter weather advisory starting at 5 p.m.
It says another 3 to 5 inches of snow could fall on eastern Long Island.
Some parts of Long Island are still digging out from the 30 inches of snow that accumulated during the last storm.
