High pressure will provide the perfect conditions for disruption to Freeview this week, especially in western areas.
Atmospheric conditions will allow TV and radio signals to travel further than normal, causing increased interference. The worst affected areas include Wales, SW and NW England. For a brief time, reception issues could temporarily spread to cover areas further east, before the high pressure gives way at the end of the week.
A Freeview relay transmitter which primarily provides a correct regional service for parts of the East Midlands city is on the move.
The Derby relay offers some households in the area the option to switch to East Midlands local news on BBC One and ITV, instead of the West Midlands-based service that is widely available.
Viewers in parts of the Anglia region need to retune Freeview today following overnight frequency changes.

Freeview changes to commence on Tuesday 5th June from 07:30 am.
