Monday's jumps fixture at Ayr has been abandoned after powerful gales caused structural damage on the course.
A statement issued by Ayr officials read: "We have had a severe storm, with high winds causing structural damage to buildings on course.
"The forecast is for winds to remain strong (50-60 mph) through today and tomorrow, thus the site has been deemed unsafe to stage a race meeting.
"We apologise for any inconvenience caused - safety is a priority."
Kelso's Sunday meeting gets under way at 12:40 GMT after a morning inspection but the conditions on the west coast have been more unforgiving.
Ayr's clerk of the course Emma Marley said: "Since we walked the track this morning the weather has been pretty hairy.
"We've had thunder and lightning and gale force winds and, unfortunately, some roofs have blown off the stables.
"The ceiling is also coming down on the stands and the safety officer has deemed the site unsafe.
"It's a shame as the track is raceable, but the weather is not improving and we can't secure the site in time for racing."
