In Italy about 1% of people die every year, which is roughly consistent with 98 people in a month. If the virus causes one year's worth of extra deaths, these will not be spread out over the whole year, so seeing 350 of them in a month of the epidemic would also not seem out of place, it corresponds to an epidemic whose peak is a few months long. So this data doesn't seem inconsistent with the linked article's estimates. Of course if you are running a morgue, then 448 instead of 98 is the relevant figure, and is likely to be very difficult to handle. And if you are running a hospital, even worse.
