Where are you getting that from? FHM's Covid-19 tracker [1] shows the most deaths occurring on 8/4. Of course, because there's a lag in the reporting that is likely to change over time. Either way, the data for yesterday is too incomplete to make any statements about yet.
Artifacts of data representation undermine the direct translation to deaths occurring on a certain day, but for the purposes of saying "middle of an outbreak" this is probably enough.
That makes sense, though I would advice against the latter way since it will show massive dips and spikes due to variation in reporting. Notably, the reports dip every weekend and there was a huge dip over Easter that took ages to get caught up.
Eh, not really. Reported deaths typically lag up to 5 days so this is mostly just that a lot of backlog was reported the same 24 hours (yesterday afternoon and this morning). Number of deaths per day have been relatively stable since the beginning of April.
