Ameren says it is sending more than 100 employees Saturday to New England to help with any problems caused by Hurricane Sandy.
Sandy is expected to be a monstrous storm that poses a serious threat for the entire Eastern Seaboard. Forecasters say Sandy is a massive cyclone, with hurricane-force winds recorded as far as 100 miles away from the eye of the storm.
Officials with Ameren say they are closely monitoring Hurricane Isaac's progress now that it has made land fall. Projections from the National Weather Service indicate the remnants of the storm could pass over Missouri and Illinois this weekend.
Kevin Anders, Ameren Missouri's manager of distribution services, says that could mean a lot of rain and - potentially - some high winds or tornadoes.
