Seven postcode areas in the West Midlands may see disruption due to this week’s weather warnings.

Royal Mail has warned of some disruption to its delivery services following the rare ‘red’ weather warning issued by the Met Office.

Yesterday the Met Office issued a rare red extreme heat warning for this week, alongside amber warnings from Monday through Thursday across much of southern and central England and Wales.

Temperatures are set to reach a peak of at least 39°C on Wednesday (June 24) and Thursday (June 25), with the potential to break June’s all-time UK daily temperature record.

Royal Mail said some adjustments may need to be made to protect the safety of its staff, and has listed a number of postcodes affected.
