Homeless shelters are a type of homeless service agency which provide temporary residence for homeless individuals and families. Shelters exist to provide clients with safety and protection from exposure to the weather while simultaneously reducing the environmental impact on the community. They are similar to, but distinguishable from, various types of emergency shelters, which are typically operated for specific circumstances and populations - fleeing natural disasters or abusive social circumstances. Extreme weather conditions create problems similar to disaster management scenarios, and are handled with warming centers, which typically operate for short durations during adverse weather.
