Gustav's leftovers arrive in Mo.

ST. LOUIS -- Rains left over from Hurricane Gustav drenched Missouri on Thursday, resulting in scattered road closures and reports of minor flooding in low-lying areas.

The National Weather Service said wet weather left over from the hurricane that hit the Gulf Coast Monday hovered over Arkansas for a few days before dropping as much as 6 inches of rain in Missouri on Wednesday and Thursday.

"This is not going to be a long-lived event," said meteorologist Benjamin Sipprell with the National Weather Service in eastern Missouri. He said the storms should be gone by Thursday evening, though some communities could get an additional inch or two of rain before the stormy weather subsided.

The Missouri Department of Transportation reported 18 road closures, primarily in central, southern and eastern Missouri, at midday. The closed roads were primarily in low-lying areas prone to flooding in wet weather.

The rain also kept golfers from a day of tournament play in the St. Louis area.

The first round of the BMW Championship was washed out by steady rain that deluged Bellerive Country Club on Thursday. The opening round will be Friday, with 36 holes scheduled for Saturday to get it back on schedule.
