During that time, as many as 19 warming centers will be available with extra seating to boost capacity.
With the Code Blue in effect, the city's outreach teams are increasing their presence on the streets to encourage people living outdoors to head to one of the warming centers.
Transportation will be provided.
This comes as wind chills are expected to dip below zero during the worst of the upcoming cold snap.
"The City is closely monitoring the weather forecasts and are prepared for any adverse weather event," said Streets Commissioner, Kristin Del Rossi. "We are ready to mobilize street pre-treating and snow clearing as needed across the city."
Anyone who needs a warm indoor place to stay may visit a warming center, where food is also available.
They may also call the Department of Behavioral Health and Intellectual Disability's Homeless Street Outreach Team at (215) 232-1984 to get a ride to one.
