Thorney Island to Bracklesham

Warning no longer in force

For two hours either side of this afternoon’s tide (14:30 13/02/2020) water may still affect Bosham Shore Road. Thereafter, tide levels should fall by approximately 10-20 cm each tide until the weekend. Storm Dennis will temporarily raise water levels again Saturday 15/02/2020, and see the return of strong winds and large waves. However the overall water level is expected to be half a metre less than seen during, and after Storm Ciara earlier this week. Minor flood impacts could still be possible this weekend, but are expected to be limited to a small amount of spray affecting exposed shore side roads, properties and fields. As the risk of flooding affecting properties is reducing, we are removing this flood alert. Please continue to take care if visiting the coastline, the strong winds and large waves will still produce dangerous conditions.

This information last updated 10:49am, Thursday 13th February.
