The Met Office is predicting that local intense showers will form across Wales and central England. The heavy showers will fall on already saturated ground which may lead to "locally significant disruption".
The period when the county will be most at risk is between 6pm and 11pm this evening.
Herefordshire Council has arrangements with some parish councils to hold stocks of sandbags for local use in areas where there is a known risk of flooding.
In rural areas, residents' first point of contact for assistance with sandbags should be their local parish council. This service is provided free of charge - for details of whether your local parish council has requested sandbags visit the sandbags page.
Alternatively, the council holds a limited stock of filled sandbags for the public to collect at times of emergency from the following depots:
- Rotherwas Depot, Unit 3, Thorn Business Park, Rotherwas, Hereford, HR2 6JT
- Kingsland Depot, Street Lane, Kingsland, HR6 9RG
- Bromyard Depot, Hereford Road, Bromyard, HR7 4ET
- Ross-on-Wye Depot, Ashburton Industrial Estate, Ross-on-Wye, HR9 7BW
The council's switchboard is open to deal with any enquiries regarding flooding and the number to call is 01432 260000.
To ensure the council's resilience team has a complete picture of how the county is being affected by floods, the team is asking that residents report any flooding either via the council's switchboard or via the form on www.herefordshire.gov.uk/floods.
