Idalia reminded me a lot of Hurricane Dennis in 2005. Very small core, weakening at landfall in the Florida panhandle. In fact, Dennis made landfall with 115 mph winds (lowered from 120 mph operationally) and a pressure of 946 mb.
I think Idalia may have been more in the 115-120 mph range at landfall, rather than the operational assessment of 125 mph. The pressure also rose to around 949 mb, similar to Dennis, and the surge was nasty and similar, but Dennis hit a more populated area of the Florida panhandle than Idalia struck.
