Environment Agency Wales is urging people to be alert over the bank holiday weekend as heavy rain is forecast across the area.
A band of slow-moving showers are due to affect most parts of Wrexham throughout today.
Whilst the outlook for Sunday appears improved, a further band of rainfall is also forecast to hit us on Monday.
Organisers are hoping that the fun day planned for Llwyn Isaf outside Wrexham’s Guildhall on Monday won’t be affected, although they have warned that it will only be held weather permitting.
The Environment Agency said there is a risk that persistent showers could lead to excess surface water on roads and flooding of drains and small streams across Wales as well as flooding of fields and low-lying land.
Residents of Llay were hit badly by flash flooding as a result of overflowing drains following heavy downpours earlier in the month.
Agency officers nationwide will be closely monitoring the situation over the weekend and will take any necessary action to clear blockages in order to reduce the risk of flooding.
People travelling to festivals or campsites over the weekend are urged to take extra care as driving conditions are likely to be particularly hazardous.
