Floodline

Floodline is a flood warning system in the United Kingdom. The system uses river and coastal monitoring systems, in areas where they have a formal flood scheme, to accurately predict the likelihood and timing of flooding. When flooding is predicted within a local target area, a flood warning message is issued through the Floodline service. The service is accessed online or by the dedicated phone line, 0345 988 1188.

There are different messages the Floodline gives depending on the situation:

FLOOD ALERT 

Flooding is possible, be prepared We endeavour to issue this message up to 24 hours in advance of expected river and coastal flooding. Flooding is expected. Flood Alerts are early warning messages about possible flooding. They prompt you to remain alert and vigilant and provide people with time to make early preparations for potential flooding. Flood Alerts are issued for geographically representative areas, usually matching Local Authority boundaries. Generally 9am-5pm, 7 days a week. However, in exceptional circumstances, alerts may be issued outside these hours.

FLOOD WARNING

But it may not be possible to give 3 hours’ notice in areas prone to rapid flooding or when water levels have escalated quicker than expected. Flooding is imminent. Immediate action is required, take measures to protect yourself and your property. 24 hours a day.
