A heat wave's end is not always clearly defined by a small drop in temperature. A decrease of a degree or two may not necessarily signal the end of a heat wave.

The atmosphere must show significant changes for a heat wave to be considered over. This means that a slight temperature drop is not enough to confirm the end of a heat wave.

Further information on when the heat wave is expected to break can be found through additional sources, which may provide more detailed updates on the situation.
