Laurel Race Course canceled its 10-race program yesterday because of inclement weather. Racing is scheduled to resume today at 12:30 p.m.

Track President Frank De Francis, acting on weather forecasts and reports of poor road conditions, announced the cancellation at about 10:15 a.m. Snow also forced Laurel to close two days last month, although both were made up.

"I'm enforcing the policy that, if by 10:15 it's snowing and there's snow on the ground, that we just cancel," De Francis said. "We've got to have some kind of uniformity for our patrons regarding these {weather} conditions. The worst thing we can do is get patrons here and then send them home."

The Maryland Racing Commission has granted Laurel's request to run 11 races Thursday through Sunday, with post time at noon. (Laurel could make up the remaining six races it lost at a future time, pending commission approval.) Saturday's program will include a simulcast of the Flamingo Stakes.

Charles Town also canceled yesterday because of the weather. Racing is scheduled to resume there Wednesday at 1:30 p.m.

Al Karwacki, longtime manager of Bowie Race Course, has accepted a position with Rosecroft Raceway and will be replaced by Dan Robertson, effective Friday.

Karwacki will become an assistant to Rosecroft chairman of the board Mark Vogel, who this month purchased controlling interest of the Oxon Hill harness track. Karwacki had retained his position at Bowie after the track ended racing operations in June 1985 and was converted into a training center.

Robertson has been at Bowie seven years, the last five as plant superintendent . . .

Max Barrow will replace Lennie Pendergraph as Charles Town Races security director . . .

Rosecroft will be racing tonight at 7:30, a makeup of an earlier snow date.
