We're going to begin Friday's episode of CNN 10 by talking finance.  What do higher interest rates mean for Americans and how might they slow down inflation?  Then we ask the question: can science predict tsunamis?  In search of that answer, we'll travel to Tonga to hear from a group of scientists who aim to map the sea floor for a better understanding.  Finally, we're looking at Groundhog Day and we'll check in with CNN meteorologist Allison Chinchar who has the latest on Punxsutawney Phil's predictions this season.
