Funny excerpt from NWS Houston:

Beyond 240 hours? Why are you asking beyond 240 hours? If beyond
240 hours you go, only pain will you find. Yes, I see what the
GFS is doing way out there, and I bring it up for the SOLE.
PURPOSE. of being a buzzkill. We are now approaching the time of
year when the GFS loves to generate tropical cyclones in the
western Gulf out of the Central American Gyre in its extended
range. The GFS does this...a lot. Every once in a great while, it
happens in real life, too! So, if someone starts buzzing about
the hurricane in the Gulf in two weeks, let us all take a deep
breath and remember that far more likely than not, this is just
the GFS reminding us that it is almost June, and nothing more.
Regardless of what one model says about a couple weeks out, it is
almost hurricane season, and we should be working on being
prepared for anything that may come in the next several months as
a matter of course. 25
