The extreme rapid intensification over the last 24-36 hours is record setting I believe. And presently it is still strengthening and will potentially set many records - I suppose I shouldn't speak too soon with 'unprecedented' but all signs indicate this will be an extreme event.
God, it’d be incredible if this became a Category 6 in 2020. Hurricane Dorian almost hit that milestone.
FWIW there is no official category 6, as 5 is deemed as essentially total destruction and there isn't much need for a 6. It's a topic of debate however.
Also Laura may reach a minimal category 5 but is unlikely to intensify past baseline 5 status.
