The Met Office has issued a yellow warning for heavy thundery showers, which pose a risk of localised flooding.
The warning is from 12-7pm today (Friday 3 August) and will mainly affect the north east.
The Met Office says to expect possible flooding of a few homes and businesses, leading to some damage to buildings or structures.
There is a good chance driving conditions will be affected by spray, standing water and/or hail, which may lead to longer journey times by car and bus. Delays to train services are also possible, as well as some short term loss of power and other services.
