Condition based on stock locations and quantity of specific location

[Majit]

I am in a situation where I need to have conditions based on the locations (warehouse) of variants and the stock it has. 

For example a product ships from different locations. location 1 = CA,  location 2 = FL

When the location CA is out of stock, I want to display that the product will be delivered from location FL. 

To achieve this, I need to put conditions with locations and the quantity of that specific location. 

Please let me know how can I do them or what objects are available to create those conditions.
