I have been looking at the Miami NWS Nexrad‘s image of Katrina¹. Very interesting.
It doesn’t have distinct hurricane features yet. There’s no eye, as such. Still, I am seeing what looks like a center of circulation. It is becoming circular after its previous blob shape.
I think of all the observational tools, radar is best at this point. Satellites are interesting, but radar is so much closer to real time and rapidly updated.
¹ – Right now, that’s just whatever’s on the Miami radar. It was Katrina when this entry was originally posted.
