FORGET about the fashion stakes, racegoers at this weekend’s Roma Cup might want to pack their gumboots and raincoats.
The Bureau of Meteorology is predicting up to 25mm to fall in the south west town this Saturday during the famous raceday.
The rain will begin on Thursday afternoon with a light shower predicted before showers and a possible storm rolls in on Friday.
The highest chance of rain is on Saturday with between six to 25mm of rain predicted to fall and a chance of a thunderstorm.
However, the rain will bring cooler temperatures for the day with a maximum of 25C.
BOM meteorologist David Crock said there was a lot of tropical moisture sitting over central Australia which move east this week.
He said some areas could see between 25 to 50mm of rain with some thunderstorms bringing heavier falls.
“As it moves east it is going to form into something of a rain band and bring quite widespread rain towards the end of the week into the weekend,” he said.
Roma Turf Club secretary Jackie Erickson said it would take a category five cyclone to call off the event and there was plenty of shelter if it did start to rain for the more than 6000 attendees expected.
"We have never had a Roma Cup stopped in 51 years,” she said.
“We had one about 15 years ago where they abandoned the race but we have got a sand track which is considered an all weather track.
“All the motels are booked out, there are no rooms and we already know the camping ground will be pretty chockers and people’s verandahs and backyards are always full.”
