Miami ? Little ghosts and goblins in cities across South Florida were stuck inside Monday night as officials urged parents to call off trick-or-treating because of the damage from Hurricane Wilma.

The power was still out in many places, and storm debris made some streets and sidewalks hazardous.

“In Miami Springs, they always have parties and tell stories. And now they have canceled that,” said a disappointed Mika Lorenzo, 9. He still planned to wear his knight’s costume.

Officials in Miami and other communities asked parents not to let their children go out after dark Monday. Several cities have had curfews since the storm hit a week ago, and some of those curfews were still in effect. But even in cities where the curfews had been lifted, officials worried about children being out in the night.

“If your kids don’t need to go door-to-door trick-or-treating this year, they probably shouldn’t,” said Miami police Lt. Bill Schwartz.

Florida Power & Light, the state’s largest electric utility, said Monday night that power had been restored to 77 percent of customers blacked out by the Oct. 24 storm, but that left 740,000 homes and businesses still without electricity.
