From the village E-Flash (and I also received two phone calls from Code Red.) I thought they were hooking up Twitter to the alerts as well, but I don't see anything there yet.
The Village of Riverside has received notification from the National Weather Service at this time that the forecast for the Des Plaines River in Riverside is predicted to rise to 9.2 feet by this evening. This is based on the current water level of over 7.6 feet and the additional rain expected today which is forecasted to be 1/2 to 3/4 of one inch of additional rain.
If the forecasted rain is received and the river in fact rises to the forecasted level of 9.2 feet there will be some flooding in Riverside. Again, this information is forecasted and may not actually occur. This is the best information available at this time.
In the event you desire sand and sand bags please call the non emergency Fire Department number (708)447-2123. You may also call this number if you have other questions regarding the current situation.
