Yes, but they probably mean "the next 72 hours from right now given in UTC".
Or maybe they mean "day" as starting from UTC midnight.
I'd guess that's actually more likely. Interesting bit of jargon.
Maybe they’re contrasting with sidereal days?
That was my initial thought, but that’s a difference of 10 mins over 3 days, and that’s orders of magnitudes more precise than should be used.
