What to Do:

The Met Office advises residents and visitors to take the following precautions:

Check if your location is at risk of flash flooding and prepare a flood plan and an emergency flood kit if necessary.

Monitor road conditions before travelling and consider amending your travel plans if necessary.

Stay updated on the weather forecast and be prepared for potential changes to the warnings.

The warnings:

While not all areas will be affected, the Met Office warns that scattered showers on Wednesday night are expected to merge into longer spells of heavy, possibly thundery rain overnight and through Thursday. Where heavy downpours occur, 20-40 mm of rain is possible within an hour or two.

Over a longer period, some areas could see more than 50-60 mm of rain, potentially reaching 80 to 100 mm if repeated batches of heavy rain affect the same locations – this is more likely during the second half of Thursday.

Friday's Warning:
