This isn't in the canon section but I'll give you the canonical take anyway.

Banshee's recieve messages from an undefined "beyond" and mostly those things have to do with people dying.

In that way they are precognitive since the people in question aren't dead yet.

In Lorraine's case, she sensed a large number of people were going to die at some point in her future and made a computerized list of those people's names. She buried the list in code and left a message for Lydia in hopes her granddaughter would get the clues and figure out the code and be able to help stop some of the death.

Meredith Walker, also a Banshee, used Lorraine's list, assigned her own dollar amounts to each person on the list and had Brunski automate it and place the list online. He then flooded the assign community with cassette tapes that explained how they could collect the money.

Everything that happens seems to follow pretty closely to what we already knew about the banshee of the Teen Wolf Universe.
