This afternoon's meeting at Wincanton has been abandoned, with the situation monitored on an ongoing basis at Haydock, Lingfield and Ascot. Gowran Park's card is currently set to go ahead, despite a yellow wind warning.
Inspections were called at the four meetings in anticipation of Storm Dennis striking.
Rain is forecast almost everywhere on top of already saturated ground which is still recovering from Storm Ciara.
It was all too much for Wincanton, unfortunately, which had been due to stage the Betway Kingway Hurdle, one of the feature races of the season at the track.
Just after 8am Wincanton's Twitter feed posted: "Racing has been abandoned. Wind gusts have reached upwards of 30mph and are predicted to rise. The back straight is waterlogged, unraceable ground and will not withstand further rainfall predicted."
Ascot, Haydock and Lingfield were all given the green light from their early morning inspections, however, the situation at all three could change as the day progresses.
The Betfair Ascot Chase is the feature race of the day and Ascot racecourse tweeted: "The 8am inspection has been passed. In view of the forecast for strengthening winds; conditions will be monitored and a further inspection will be called if conditions deteriorate to the extent that the race meeting may be at risk. The current going is Soft, Heavy in places."
Haydock is set to stage the Unibet Grand National Trial and the situation is similar on Merseyside.
A tweet read: "Haydock Park has passed the precautionary inspection and is fit to race at present. However, due to the severe weather forecast later today, we will continue to monitor the conditions - a further inspection will be called if conditions deteriorate."
Lingfield is in the same boat, but there are currently no issues at Newcastle ahead of their evening meeting, however, the situation is also being monitored there in case conditions worsen.
Racing in Ireland comes from Gowran Park, with the Grade Three Red Mills Trial Hurdle and the Grade Two Red Mills Chase set to feature on a seven-race card.
Conditions at the track are being monitored due to a yellow warning for high winds.
