Does Hurricane Irene fit a logarithmic spiral?

I made a Geogebra applet to see if it does. Enjoy.

Parametric equation:
![x=b*cos(t)*e^{at}](http://s0.wp.com/latex.php?latex=x%3Db%2Acos%28t%29%2Ae%5E%7Bat%7D&bg=ffffff&fg=000&s=0&c=20201002)
![y=b*sin(t)*e^{at}](http://s0.wp.com/latex.php?latex=y%3Db%2Asin%28t%29%2Ae%5E%7Bat%7D&bg=ffffff&fg=000&s=0&c=20201002)
![-11.7\le t \le 3.4](http://s0.wp.com/latex.php?latex=-11.7%5Cle+t+%5Cle+3.4&bg=ffffff&fg=000&s=0&c=20201002)
