Tropical Storm Bertha has now weakened into an Atlantic storm and will track towards the UK during the next few days, according to the Met Office.
The office has been assessing the likelihood of the UK seeing any effects from Bertha by using its own forecast models alongside models from other world-leading forecast centres.
At the moment southern parts of the UK look as though they are most at risk. However, there is also the possibility that the storm could move across northern France as a weak feature and also a risk of a more intense system affecting the UK more widely.
The remains of hurricane Bertha, over the western side of the Atlantic, will come steadily towards the UK during the next few days. The transition from a tropical to an extra-tropical feature is a particularly hard one to forecast with confidence, so there are still some differences in the location and intensity of the resulting depression, which is expected to pass over, or close to, the UK from early on Sunday.
Chief Forecaster, Eddy Carroll, said: “There is still considerable uncertainty surrounding this weekend’s weather, with the potential for heavy rainfall and strong coastal winds, along with large waves.
"However, there is a chance that the system may pass to the south of the country, or spread heavy rain even further north. Rain and strong winds may well bring disruption, especially in the south, and people should stay up to date with the latest Met Office warnings.”
The Met Office said it is worth noting that parts of the UK will see some heavy rain on Frida.
Craig Woolhouse, Environment Agency Flood Risk Manager, said: "Heavy downpours, some slow-moving, bring a risk of localised surface water flooding to parts of the Midlands, the north-west and eastern areas of England on Friday.
"On Sunday and Monday a combination of high spring tides and strong westerly winds brings a possible risk of flooding to the south-west coast of England and along the Severn Estuary while heavy rain may also lead to localised surface water flooding in parts of southern and central parts of England. However, the forecast remains uncertain so we advise people to regularly check the flood risk situation over the next 48 hours.
"The Environment Agency is continuing to monitor the situation closely."
