Temperatures will build again later this week and over the coming weekend,
likely peaking on Sunday and Monday. Some exceptionally high temperatures
are possible and cumulative effects of warm nights and hot days are expected
to bring widespread impacts to people and infrastructure. This period of hot
weather is expected to continue into the early part of next week, hence an
update extending this warning into Monday is likely.
