Here's an idea... depending on how many bettas you have... gather up your smaller tanks and keep them in the basement (covered so no insects or dust get in) along with bottled spring water, water conditioner, and fish food. Keep a bagged blanket next to the supplies (if you have an unfinished basement like me, as it it will keep dust off of the blanket)
In case of an emergency, cup them quickly and bring them down with you. Then you can pour the bottled spring water and conditioner in the small tanks and throw the blanket over the tanks/bowls/containers so it can protect them a bit.
Note one thing though... if it's a tornado, RUN. Do NOT stop to get your fish. I'm sorry to sound cold with this, but I have been in a tornado. While I had plenty of warnings to get ready and get my animals to the basement throughout the day, my cousin lives in tornado alley in kansas. And sometimes all you have is the noise of the sirens and 20 seconds to hightail your butt to safety. I love my bettas, but they are not worth risking my life over. The last time a tornado almost hit us last year, we didn't have much warning, and I couldn't find one of our cats, so I had to leave her upstairs. We didn't get hit in the end though.
