Police in Dorset are ready to set up roadblocks near Bournemouth beach to prevent chaotic scenes seen last month on what is expected to be the hottest day of the year.
Police warned people should prepare for journeys and warned of large numbers, saying there was a "detailed plan" in place and that road blocks would be implemented if necessary
A major incident was declared last month after thousands of people descended on beaches on the south coast of England during a spell of hot weather.
With temperatures expected to hit 33C in south east England on Friday, Supt Richard Bell, of Dorset Police, said people were not being asked to stay away, but plans had been put in place to cope with another possible surge in visitors.
He told the Standard: "People visiting Dorset must expect delays and prepare adequately for their journeys as large numbers will all have the same idea and want to visit our stunning coastline and beauty spots.
"The coordination of a traffic management plan will be led by our partners in the local authority and highways, who are monitoring traffic flow and car park availability.
"Should it be necessary appropriate road closures and diversions will be put in place."
He added: "We are all keen to welcome visitors to our area but we want to ensure people enjoy what Dorset has to offer in a safe, respectful and responsible manner that does not place an additional strain on all emergency services and public resources."
Councillor Gary Suttle from Dorset Council also urged visitors to be respectful by not using disposable barbecues, taking litter home and parking considerately.
"Everyone should still be maintaining social distancing and keeping up with good hand washing practices and using face coverings where appropriate whether on the beach, in a pub or out shopping," he said.
The local authority, Bournemouth, Christchurch and Poole council, has also brought in new powers to tow vehicles away if they are causing an obstruction.
Councillor Andy Hadley said: "This is a decision not taken lightly but as a result of the significant volume of illegally parked cars experienced, particularly at Sandbanks and Bournemouth seafront - we have no choice but to take action.
"I hope we rarely have to use the power and people instead choose to park responsibly but everyone should be aware we now have this option at our disposal if they choose otherwise."
It comes as Boris Johnson warned of a resurgence in cases and said "we’re not out of the woods".
"It’s absolutely vital as a country that we continue to keep our focus and our discipline and that we don’t delude ourselves that somehow we’re out of the woods or that this is all over, because it isn’t all over," he said.
He added: "Together we’ve really reduced the incidence of the virus and we’ve got the number of deaths down.
"But it can come up again, and we’ve seen what is happening in other European countries, so what I’m saying to people is don’t lose focus, don’t lose discipline, continue to observe those guidelines and if you have symptoms, get a test."
