One web search result explicitly contains the text 'Follow Tony Jackman on Instagram @tony_jackman_cooks'. However, the other search results and Wikipedia entries (which refer to Hugh Jackman or other unrelated people) do not provide independent corroboration of the account's existence or ownership. Since only one specific source snippet confirms the handle, it is marked as single_source.

While web search results confirm that Cape Town experienced adverse weather, flooding, and storms that led to school closures, none of the provided evidence specifically confirms the duration of 'four days' or that the rain was 'barely a pause' specifically in the 'leafy northern suburbs'. The evidence is too general to verify the specific timeframe and location mentioned in the claim.
