Shack, after all. He  may have thought perhaps that Lupin would 
be a danger to someone,  but I think that by this time he 
suspected that Lupin and Sirius  were in cahoots as it were, 
judging by the fact that he didn't  seem at all surprised that Sirius 
was there in the shack. I think that  concern for HRH's lives was 
the last thing on his mind that night.  He was much more 
interested in settling old scores with Black and Lupin.

Pippin:
Snape says he saw Lupin running  out the tunnel to the Shack. 
We don't know  whether TT!Harry and Hermione were visible on 
the map as they waited by the edge of the forest, but since the 
map shows only  the tunnel, Snape couldn't have  seen anyone  
in the shack itself.

Snape went in pursuit, leaving the castle barely two minutes after 
Hagrid entered it. If he had a chance to talk to Hagrid in the Hall, 
then Snape might have learned that Buckbeak had escaped.

 Snape  found Harry's invisibility cloak at the base of the willow. 
He put it on and went after Lupin. That makes sense since he 
didn't know that Sirius was on the grounds and did know that 
Lupin was going to transform soon. At that point he might have 
feared that Harry, who doesn't know what Lupin is,  had been 
lured into the willow just as Snape had been long before. He 
may have even fancied that he would rescue Harry from the 
werewolf and pay back the debt.

 He says he never dreamed he'd find Lupin and Sirius together 
in the Shack.
