The National Weather Service issued a flood warning for the Kankakee River at Shelby, affecting Lake and Newton counties.
The warning is in effect until further notice.
At 9:45 a.m. today, the river was at 9.1 feet. Flood stage is 9.0 feet.
The weather service reported minor flooding already is occurring and is expected to continue as the river rises.
Forecasts show the river will climb to near 10.5 feet by Saturday afternoon and then begin falling.
At 10 feet, flooding affects county and local roads, with Sumava Resorts and Wildwood Estates expected to experience some flooding, according to the weather service.
Overnight rainfall above the Kankakee Basin ranged between 0.5 and 1.5 inches. An extra 1 to 2 inches of rain is possible by Friday morning.
Drivers who encounter a flooded road are advised to turn around and use an alternate route.
Flash flooding can happen after just a few inches of heavy rainfall, according to Indiana State Police.
Safe driving tips from police include the following:
- Always carry a cellphone and charger.
- Pay attention to local media reports and heed warnings issued by the National Weather Service.
- Never drive around barricades at water crossings.
- Reduce speed and never enter flowing water.
- If you end up in water, abandon your vehicle, exit through a window and climb on top of the car. Call 911. And "ride the top like a boat," because vehicles usually float for several minutes.
