Devon & Cornwall Police and partner agencies are warning the public to be aware of expected storm conditions across the peninsula in the next 24 to 48 hours.
Incoming Storm Ellen is likely to see high winds combining with unusually high spring tides to bring the risk of coastal surges and flooding – particularly to those in coastal communities.
Exposed coastal areas are expected to see waves of up to nine feet coupled with strong south west winds – bringing with it dangerous seas and strong rip currents.
Anyone planning a trip to the coast or beach is asked to check tide times and be aware of fast moving water unlikely to be safe for water-based sports and activities.
Police are asking the public to heed the RNLI’s warning to visit lifeguarded beaches whenever possible and avoid storm watching if swells become high.
Chief inspector Tom Cunningham said: “We are aware there is many thousands of tourists in our coastal communities currently who may not have experienced conditions which we are expecting or be aware of the danger they can bring.
“We would ask everyone to heed the advice of the RNLI and HM Coastguard by not putting themselves, and indeed emergency responders, at risk by entering dangerous waters.
“Beaches are a huge draw to tourists in our region, but our coast needs to be respected by all.
“If you or someone else is in trouble in the sea, you should call 999 and ask for the coastguard.”
