Areas most at risk include Lyme Regis, Charmouth, Seatown, West Bay, Bothenhampton, Burton Freshwater, Burton Bradstock, Cogden Beach, Chesil Beach, West Fleet, East Fleet and particularly at Chiswell. Further flooding is possible at Chiswell throughout the morning due to Storm Austin bringing force 7 to 8 high winds and large waves. 

We are closely monitoring the situation . 

Exposed coastal areas may be hazardous due to strong winds and large waves. Avoid coastal roads, footpaths and carparks, which may be flooded.
