Hundreds of Indianapolis residents have gotten sandbags to protect their property from heavy rains expected this weekend from Tropical Storm Isaac.

Department of Public Works supervisor Stephen Brown says cars began lining up for sandbags shortly after the lot opened at 7 a.m. The line stretched at least 100 deep by mid-day, and some drivers waited more than 90 minutes.

Many residents say they are trying to protect property in flood-prone areas.

"I'm very worried that my whole downstairs will flood,” said Malinda Coleman. “Just from the little rain we got last week, half of my downstairs had gotten wet, so I know with seven inches coming I'm gonna need it."

National Weather Service meteorologist Marc Dahmer says the latest forecast models call for Isaac's remnants to drop between two and five inches of rain between Friday and Tuesday. Some spots could see higher amounts, and flooding is possible.

Showers from Isaac have already entered the state, but the heaviest storms are forecast for Saturday night and into Sunday.

Meantime, some Indiana cities are pulling the plug on Labor Day weekend events due to weather concerns.

That includes two parades and the "America We Remember'' celebration in Indianapolis.
