Little Irma comes to visit Houston

That tiny swirl in the middle of the Atlantic is Irma, coming straight for Houston.  The big swirls set the stage for hurricanes and they are slow to change.  So lots of hurricanes follow the previous.  Whether they get big depends on how much heat energy the previous one sucked out of the ocean.  Harvey only became a 4 just before landing, so Irma may make it all the way to Houston.
