Big thaw: eyes turn to flooding potential

•Illinois: Carbondale, Effingham, Mount Vernon
•Missouri: Cape Girardeau, Poplar Bluff
•Ohio: Cincinnati, Dayton, Portsmouth
•Kentucky: Louisville, Lexington, Bowling Green, Paducah, CovingtonAdding an inch or so of rain to our snow pack and frozen ground over roughly a 5-day span shouldn't be a big problem. Of course, that does not mean there won't be flooding or issues. Any time it warms up and rain falls in the winter, there's a risk of river rises, lowland flooding and minor city flooding. Something we may see more of over the coming days are ice jams. When rivers freeze over and thaw, the ice cracks and splits apart, creating chunks of ice that flow down the river. That in itself can be a headache, especially for those who live along rivers. Even with the threat of ice jams on Michiana rivers, the overall risk of flooding beyond the "Minor" level is quite low. As it stands now, the National Weather Service has all area rivers staying below or just above "Action Stage," which is the lowest threat level (Action - Minor - Moderate - Major). Regardless, it appears as though conditions will be supportive of at least minor street flooding, noticeable river rises, ice jams, lowland flooding, and instances of basement flooding. If you live in a flood-prone area, officials say it's important to prepare for a flooding event.
