Today, the City of St. Louis announced a new set of emergency shelter activation levels, based on weather conditions, to increase predictability for those in need of shelter as well as the City and shelter providers.
These activation levels, developed as part of the Winter 2025-26 Code Blue Plan in accordance with and as required by Executive Order 93, are designed to ensure a timely and scalable response to severe cold-weather conditions, prioritizing the safety of vulnerable populations. The plan was developed in collaboration with the Department of Human Services and St. Louis shelter providers.
"The Department of Human Services and our community partners have done an outstanding job scaling up emergency shelter to levels previously unheard of, providing a safe place to stay for unhoused St. Louisans and those whose homes can't be kept warm because of tornado damage," said Mayor Cara Spencer. "While providing shelter for hundreds, these teams have also been at work developing a plan for sustainably and predictably activating St. Louis shelters for the rest of the winter. I am proud of and thankful for these efforts that create a strong framework for how we care for the most vulnerable in our society on the coldest days of the year."
The activation levels provide a structure for how the City and its partners may adjust winter operations in response to changing weather conditions. Each level includes minimum threshold conditions that help guide decisions about readiness and response. However, the City may activate at a higher level when conditions warrant, including circumstances such as expected precipitation, prolonged cold, limited shelter capacity or other emerging risks.
Below, the Code Blue activation levels and process are outlined. The full Winter 2025-26 Code Blue Plan is available on the City website.
