Despite the thunderstorm warnings clearing by the early hours of tomorrow, the bad weather is set to continue over the next couple of days, as yellow rain alerts come into place.
The weather office has warned that "heavy rain may produce some flooding and transport disruption".
As well as the possibility of power cuts, the Met Office said that rural communities may be cut off by flooding.
Advising those who may be impacted by the treacherous weather conditions, the weather office said: "Check if your property could be at risk of flooding. If so, consider preparing a flood plan and an emergency flood kit. Give yourself the best chance of avoiding delays by checking road conditions if driving, or bus and train timetables, amending your travel plans if necessary."
