Operation Deep Freeze (ODF) is Tucson's winter severe-weather emergency shelter for people experiencing homelessness. ODF goes into effect when weather predictions are for overnight temperatures of 40°F or lower with rain, 35°F or lower without rain, or when wind chill factors indicate a health hazard from exposure. You do not need an ID or a TB card to participate in ODF.
For more information on how to find shelter when Operation Deep Freeze is on, please visit our ODF webpage.
