The Foreign Office has issued a new travel warning for Brits heading on USA holidays, as New York continues to be affected by a "hazardous" orange haze caused by Canada wildfires in Quebec and Nova Scotia.
The UK government is warning travellers that the smoke is causing "poor air quality", not to mention that it could also cause disruption to travel plans.
The updated advice reads: "Smoke from wildfires in Canada is currently causing poor air quality across parts of the East Coast of the USA. You should check AirNow.gov for updates on the current air quality in your location and follow the advice given by the US authorities, including wearing a face mask to protect yourself.
"Air travel may also be disrupted. You should check the status of your flight with your airline before travelling."
Over 400 blazes burning have left 20,000 people displaced in Canada, while the ensuing smog has blanketed the US and Canada, affecting millions of people as air pollution has reached record levels.
New York City has been covered by the smoke from the wildfires, with residents describing the smog as "apocalyptic" and looking "like something from Mars".
Authorities have also warned people to stay inside and wear a mask if they have to go outdoors.
A Code Red air quality alert is also currently in place in place as forecasts show winds are continuing to push the 'hazardous' air south.
It's worth noting that the government is not advising against travel - so if you have a trip booked, it should be able to go ahead as planned.
It's understandable that some Brits may want to put off their trip. However, in this scenario it's unlikely that you will get a full refund if you choose not to go. (If it's the travel firm which cancels the holiday, then you are entitled to your money back).
If you choose to cancel the holiday, check the T&Cs of your booking but you may need to pay a cancellation fee, which can vary depending on factors such as the time before you travel, your chosen airline, and what it will cost the travel firm to cancel your trip.
Some flights have been delayed and temporarily grounded, so make sure you know your rights if you have a holiday or flights booked.
There are three main New York airports; La Guardia, Newark and JFK. Generally most flights between New York and the UK have been operating on time or with some minor delays, but check ahead with your airline before you set off for the airport.
For example, earlier this week La Guardia temporarily grounded flights, although services have since resumed.
