The Met Office Chief Forecaster said today (Saturday August 9th) hurricane Bertha is expected to move towards the UK before deepening tonight and tomorrow morning (Sunday August 10th).
There is the potential for severe weather over much of the UK during Sunday as a depression tracks over, or close to, the UK.
There continues to be a great deal of uncertainty in the forecast but there is a risk of flooding due to heavy rain as well as very strong winds and large waves.
Given the unseasonable nature of the weather this could be sufficient to disrupt transport and make outdoor activities dangerous.
This is a particularly volatile situation and this alert is likely to be updated as the event approaches.
A yellow rain warning was issued at 11.17 am today valid for 12.15 am to 11.45 pm tomorrow.
