People travelling to France via the Channel Tunnel have been advised to bring food and drink as lengthy queues continue at the Port of Dover.
Roads in Kent have been hit by long delays in recent days due to a shortage of ferries caused by the suspension of sailings by P&O Ferries after it sacked nearly 800 seafarers without notice.
The operator said it plans to resume operations on the Dover-Calais route next week pending regulatory approval.
Toby Howe, tactical lead at the Kent Resilience Forum, advised travellers to France to “allow a lot of extra time”.
He told BBC Breakfast the delays had been caused by “the perfect storm”.
“In Kent we have had the perfect storm,” Mr Howe said.
“Yes, we had the P&O issue. We then had a storm at sea which meant that a lot of the ferries couldn’t cross overnight.
“We had a few problems with the customs process, etc.
“We then had some snow. We then had a train in the tunnels, so all of these things had added up to culminate in the problems that we have got for poor Kent at the moment.”
He said there had also been an IT issue with processing documents.
Mr Howe said: “Luckily things have been put in place now so that isn’t a delay but that was something that contributed to those initial delays.
“So last weekend Dover really suffered because of all of that congestion.
“But we have put traffic management plans in place now so that things can flow through Dover and Dover can still function as a town, and Eurotunnel and the Port of Dover are able to operate as they need to.”
He added: “Make sure you have got some food and drink because there will be delays.
“A lot of the minor roads therefore are chock-a-block.”
Mr Howe advised travellers to look into the traffic on different routes before making their journeys.
He said that summer, when traffic is likely to get busier, was a “worry”.

Mr Howe added: “What we need are plans in place moving forward because every getaway, Kent could suffer.
“So we need plans in place so that we can actually restrict that traffic coming in.
“Hopefully, when the ferries are back from P&O that will assist as well.
“But there will always be some problems as we continue with this sort of thing.”
He added that it should not be Kent that “suffers” every time there are travel issues.
Labour has urged the Government to intervene amid warnings holidaymakers hoping to get away for Easter face long delays and severe disruption at UK airports.
Manchester Airport has urged passengers to arrive three hours before departure to avoid missing their flights as staff shortages have led to the build up of lengthy queues.
After cutting thousands of jobs during the coronavirus pandemic, the aviation industry in general is suffering from difficulties recruiting staff and waiting for security checks to be passed on new employees.
There has also been a recent rise in coronavirus-related staff sickness.
Shadow transport secretary Louise Haigh has urged ministers to prioritise staff at Manchester and other major airports for Home Office security checks so they can start work as soon as possible.
Ms Haigh MP said: "Brits are facing a week of travel disruption, and this Conservative Government are missing in action.
"Tory ministers need to step-up and act to ease the disruption. The Government need to begin clearing the huge backlogs in security checks so airport staff can safely begin work."
Ms Haigh also called on ministers to open emergency talks with ferry operators and Eurotunnel to increase capacity following the suspension of services by P&O Ferries.
With up to 70 sailings a day still reportedly affected, roads in Kent have seen long tailbacks as lorries queue to get into the port of Dover.
"They (ministers) need to look urgently at what powers they can use to force P&O Ferries to re-employ trained and experienced staff on their original terms to get the routes up and running," Ms Haigh said.
Heathrow, Gatwick and Birmingham airports have also been hit by delays and cancellations in the past week.
The boss of the airlines watchdog has written to UK airlines expressing frustration and concern for holidaymakers.
