Manx Grand Prix competitors have been warned to batten down the hatches as bad weather approaches.
Organisers say a yellow weather warning means awnings, tents, and gazebos at the paddock could be at risk overnight.
Ronaldsway Met Office is also advising people not to park on Douglas promenade tonight as high winds may bring coastal overtopping.
Those staying on campsites have also been warned about the approach of the tail end of Hurricane Ernesto.
