A yellow weather warning for rain has been issued across parts of Cornwall and Devon.
The holiday hotspots could be hit by flooding with bus and train service likely to be affected.
Flooding and spray on roads could also make journey times longer.
The Met Office has issued the warning from 6pm on Friday until 9am on Saturday.
The Met Office said: “20 to 40 mm of rain is likely to build up widely by Saturday morning and 50 to 75 mm rain is likely over and near areas of higher ground, especially Dartmoor.”
“Give yourself the best chance of avoiding delays by checking road conditions if driving, or bus and train timetables, amending your travel plans if necessary,” the Met Office added.

Travellers to and from France and Spain are worst affected.Ben Smith, chief executive of Air France-KLM, said in March: “The shortage of air traffic controllers [in France] is 20-25 per cent, which means many of our flights are going to be delayed, and we already know this.”

More than a hundred workers at Gatwick airport are striking over pay and pensions this Easter weekend.
Members of the Unite union working for ground handling firm Red Handing have rejected a last-minute deal to call off the strikes.
That means some baggage handlers, check-in staff and flight dispatchers will strike from Friday until Tuesday morning.
The industrial action could affect about 50 flights a day.
Unite said there would be “major disruption” for passengers flying with Norwegian, TAP and Air Peace airlines.

But Nick Williams, head of passenger operations at Gatwick, said only a small number of airlines would be affected.
“It’s a very small number of airlines who don’t operate a huge number of flights, so we’re not talking about big-scale impact,” he said.
“We’re working really closely with those airlines to try and mitigate that impact and hope that as many of those flights operate as close to schedule as possible.
“We’d advise passengers to check their airline of the weekend.”

On Good Friday morning queues are building up at Dover.
The Port of Dover said at 8.10am: “P&O traffic is causing extended processing times at Border Control.”
Passport checks for France are conducted at the port before travellers board ferries.
Motorists are told to expect a wait of around 40 minutes ahead of the French border post, and the same length of time for P&O Ferries check-in.
The wait for DFDS Ferries check-in is 15 minutes.

Dover queues build with delays for French border control (Dover queues build with delays for French border control)
DFDS Ferries says: “We are aware of the queues to arrive at check-in. Please be assured that once you arrive at check-in. we will ensure you are checked-in on the first available departure.”
In previous years, Dover has been the scene of severe delays during the Easter holidays, as coaches converge on the UK’s main ferry port.
But the failure of the European Union to introduce the entry-exit scheme as promised in November 2024 means journeys are smoother than they might have been, with no need for vehicle occupants to be fingerprinted or photographed.
Bigger problem are likely to face motorists returning from France to Dover between Saturday 19 and Monday 21 April.
Last weekend queues of 90 minutes built up for the border formalities at Calais, where both French and UK frontier staff check documents before passengers board their ferries.
