Dana White and Donald Trump handed nightmare hours before UFC Freedom 250

Dana White and Donald Trump have been handed a nightmare just hours before the UFC Freedom 250 card gets underway.

The event will take place on the South Lawn of the White House on June 14 and coincides with Trump's 80th birthday, with Ilia Topuria defending his lightweight crown against the division's interim champion Justin Gaethje.

Alex Pereira and Ciryl Gane go head-to-head for the interim heavyweight title, while Sean O'Malley faces Aiemann Zahabi in a bantamweight clash.

The UFC are expected to make a loss on the event despite some guests paying $1.5 million for special access, with around 4,300 spectators set to watch from the South Lawn.

Around 85,000 service personnel will also watch the fights from nearby Ellipse Park, which is located south of the White House.

A 92-foot-tall steel structure dubbed the Claw has been installed as a makeshift venue, under which the Octagon will be placed.

Due to the event being the first of its kind, concerns have now been raised about what happens if adverse weather conditions occur.

According to AccuWeather, Washington will be hit with heavy thunderstorms in the afternoon, with "downpours and lightning" likely to "impact the events at the White House".

Adverse weather would no doubt be an unwelcome distraction ahead of the prestigious event.

The Octagon will be fully covered, but spectators are not so lucky and may be advised to bring a rain mac.

The rain is one concern, while hot and humid conditions may cause fighters to fatigue quickly. The humid conditions are also expected to attract bugs such as gnats, adding yet another problem for the UFC to deal with.

UFC president White has already acknowledged "rain, lightning and a ton of bugs" as the organisation's "three big problems" ahead of the historic card.

Speaking to The Hollywood Reporter, White said: "As soon as I left the White House, I called my head of production, Craig [Borsari], and said the black fly experience that I just had is brutal.

"So imagine this massive, powerful claw and the lights that are going to come with it. You're going to have gnats, moths, maybe bats. I don't know what the hell's going to show up, but these are all the things that you have to think of leading up to this thing."

The 56-year-old also confirmed that he had been working with organisers to prepare for the aforementioned issues.

Bantamweight O'Malley has also voiced his concerns about the environment influencing the outcome of fights.

"It's at the White House, so you've gotta deal with whatever you've gotta deal with," O'Malley told MMA Junkie. "That would suck, to lose because of a reason outside of your skillset. May the best man win. If something plays a role because it's outside and it affects the fight somehow, that would suck.

"It's unfortunate, but none of us signed the contract thinking it was inside, you know what I mean? We all know it's outside. We all know what we're getting into. Maybe not to an extent; we don't know what all is gonna happen, but we all know it's going to be outside and we're going to have to possibly deal with stuff. We all signed it."
