Following steady rain this morning, Gulfstream Park has moved all of Thursday's scheduled-for turf races to the dirt track, which is listed as Fast.
Of the remaining races the fourth and sixth have been taken off the turf.

The carryover on the Rainbow 6 is $178,536.
The 20 cents per combination-only bet will be on races four to nine, with the sequence scheduled to start at 1:30 p.m.
Gulfstream is guaranteeing that Thursday's Rainbow 6 jackpot pool will be at least $350,000 if there is just one ticket with all six winning horses. Such a ticket would take down the jackpot of the full carryover plus 80 percent of the day's new Rainbow 6 bet.
If there are multiple tickets with all six winners, Gulfstream will take out 20 percent of the day's Rainbow 6 bet. It will then divide 56 percent of that bet among the tickets with six winners and add 24 percent to the carryover.
