A yellow weather warning is in place in Powys ahead of the arrival of storm Frances this week.
The Met Office said that from Monday night there will be wind gusts of 60mph and potentially 70mph in exposed western locations of the UK.
The rain is expected to be heaviest in Northern Ireland and south-west Scotland where 60-90mm of rain could fall as the storm moves from west to east, the Met Office added.
But Powys will also be hit, with a yellow weather warning for rain in place covering Newtown and Machynlleth, and a yellow warning for wind covering the entire county.

Chief Meteorologist Andy Page said: "The UK is in for another unseasonably wet and windy spell with Storm Francis arriving on Tuesday. There will be strong winds and heavy rain, especially in the west of the UK.
"A number of severe weather warnings have been issued and these warnings can be updated regularly so please keep up to date with the latest Met Office forecast."
The warnings suggest that there could be surface flooding on roads bringing large amounts of spray and, subsequently, longer journey times.
