Interesting structure in #Grace right now on the Cuba radar. Looks like a small eyewall developing, but a larger band wrapping around. It "looks like" an ERC, but it's too early in the process for that - just a lot of bands. That outer one has the strongest winds for now. pic.twitter.com/IB9Tr3yGbF
