Will Irene ruin my fun in D.C.?

Well folks, hurricane Irene is on its way to destroy the entire East Coast, if we are to believe the weather channels.  Included in said East Coast is a little town called Washington D.C. and more specifically the tournament known as the Nova Open.

Up til now, I've been a 'for sure' to go there, for about a year.  My plane leaves tomorrow at 7:20 am, which would get me there much sooner than the Hurricane is supposed to arrive.

Further research shows me however, that D.C. probably won't be affected a whole bunch.  Here's a fun picture of how the projected winds will affect D.C:

So, maybe not a huge deal?  This picture makes me more concerned though:
