Seeing evidence of secondary eyewall development in #Idalia right now. Probably won't have time to weaken the storm much before landfall, but the expansion of the wind field in the outer region (as seen on radar) could be important for places like Jacksonville and Tallahassee. pic.twitter.com/4xV3NrC6iU
