Yes, but at the moment it's still within the range of the previous 5 years, which is not a long time period. If it continues spiking at the same rate for weeks longer, then yes it will be unusual. But the fact that you don't have to go back very far to see multiple examples of spikes of this size or greater, means that as of this point it isn't yet that unusual. If it keeps going for weeks at this rate, then it is a big deal, of course.
