As someone who is not a native to the gulf coast but has lived here over a decade now, Alan Sealls is about as beloved a weather person as you could have in Alabama. He's known for being calm and educational without being patronizing or sensational, and the gulf coast will be worse without him on TV. I grew up watching James Spann and hold Alan in the same high regard as his compatriot up in Birmingham as far as quality goes.
The good news is, according to his announcement, he'll still be running his weather website and teaching at USA, so he won't be leaving the port city anytime soon.
The bad news is, and this is strictly my opinion, this is further evidence that WPMI and WEAR are circling the drain because of Sinclair's aggressive cost cutting. In the back of my head I knew it was only a matter of time before one of the big names on NBC 15 left after they axed the weekend news and instead piped in WEAR in an attempt to cover the time slot. That whole thing has been a freakin' disaster, by the way. The Pensacola weekend crew clearly doesn't have the institutional knowledge of Mobile or Baldwin County that the WPMI people possess, and the technical glitches are legendarily embarrassing. I think it's been a solid month of weekend news programs where the taped segments (interviews, packaged news from other affiliates, etc.) has zero audio other than background b-roll sound. No reporter narration on ANY story, for weeks on end! How could they not know about this issue? It's so bad I keep watching just to see if it ever gets fixed.
I fully expect Kym Anderson, Darwin Singleton or Andrea Ramey to nope the heck out of there eventually, leaving us only with recent college grads still wet behind the ears.
