I'd like to keep this thread focused on the impacts on racing, tracks, horses and connections rather than dive into model analysis, path speculation, and so on. There are many other websites for discussing the storm and forecasting.
Gulfstream Park has cancelled all racing for Sunday and Monday (September 1st & 2nd), and everything is shutting down tonight (Saturday 31 August) at midnight. Horsemen stabled at Gulfstream Park and its satellite training facility in Palm Beach County, Palm Meadows, have been told they may stable at whichever facility they feel more comfortable depending on the track of Dorian.
