How much of a warning would we be able to give before the Yellowstone Supervolcano erupts?

The yellowstone caldera has been steadily rising in the past years, but most geologists do not see an eruption as a threat in the forseeable future. What are the indications that an eruption is "imminent." Have geologists been able to do a good job at predicting other eruption events elsewhere on earth, even if it's only ~30 minutes in advance?

The most tell-tale sign a volcano is about to blow its top is harmonic quakes that result from magma moving towards the surface. However, the time between a harmonic quake and a volcano blowing its top could be anywhere from a second to hours. Sometimes, harmonics occur in a volcano, but it doesn't erupt. Volcanoes are kind of temperamental and unpredictable. The issue with saying Yellow Stone is safe is people often take that as an absolute confirmation. The real truth is that Yellow Stone doesn't show any immediate signs of erupting. However, just because it doesn't appear to be on the verge of erupting, it could just randomly erupt one day. It could blow its top anywhere from tomorrow to the next ten thousand years.
