Yes, been there done that. Christmas day 6 years ago. You tube it for vision of the event. I've seen larger hail before but never for such a long period of time. Hail storms are usually short events, this one went for over a hour. It stripped all the foliage of the trees, it was like winter in a deciduous forest. The strength of the hail even knocked hives over.
It finished the flowering to say the least. I had about 50 hives in the storm, all the queens stopped laying for several days, it was quite interesting to see the laying pattern. The bees had been on the last of red box ( eucalyptus polyanthemos ) and yellow box ( eucalyptus melliodora ). The trees put on new growth very quickly as this was out of its normal cycle it then followed some of them with flowers that quickly dropped off. Then infestation of insects on the massive amounts of new growth, lerps, scarb beetle etc. The trees looked terrible for two years. Then growth at a normal time. Then four years after the event a massive flowering that yielded more honey than I could handle.
So hang in there if it comes back like it did for us it will be a great honey flow in 4 years or so.
