The rain prevents brining the roads ahead of time so they plan to hit the streets with salt as soon as the snow begins to fall.
"This is our ninth event that's coming up. Most of them have been nuisance events, small events that don't require as many resources. We have approximately 40,000 tons of salt on standby," said Clarena Tolson, Philadelphia Streets Commissioner.
Crews will be hitting hilly neighborhoods like Manayunk early and often.
The city is asking residents of these tight streets to stay off them as much as possible to make room for the trucks.
PennDOT is also hitting the major highways through town. The biggest concern is ice.
"When you have that amount of snow and ice on trees and limbs, it can cause a situation where it starts falling down. It can impede the roads and anything that slows our trucks down, it gives us less time to get our salt down," said Nick Martino, PennDOT.
City streets can become gridlocked with the least amount of snow, especially during rush hour.
Road crews expect to have a much easier time clearing the roads Saturday.
