Heavy rain accompanying today's thunderstorms are expected to swell streams and produce some minor flooding in Kane County, the National Weather Service said.
Monday, the Weather Service issued an urban and small stream flood advisory for Kane County, northern DeKalb County and portions of Ogle County.
The NWS advised that Monday morning's storms had produced about 2-3 inches of rain thus far, with an additional 0.5 inches of rain still expected to come later in the day.
The NWS noted that the flood advisory includes the Tri-Cities, Aurora, Elburn, Maple Park and North Aurora, among other communities.
In the advisory, the Weather Service said water runoff from the storms will cause "elevated levels" of water on small creeks and streams, as well as ponding of water on roads, viaducts, underpasses and low-lying areas.
The advisory was scheduled to expire at 4 p.m. Monday.
Storms are expected to end largely around 1 p.m., the National Weather Service forecast said, but a chance of rain and thunderstorms will remain in the area throughout the day and evening, and continue through Tuesday.
Heavy rains are expected again Tuesday.
Temperatures are expected to climb into the mid- to upper-80s both today and Tuesday.
