* ADDITIONAL DETAILS...
- At 1034 AM CDT, various rainfall observations, automated river
gauges, and ground-truth reports from emergency management
personnel indicated that at least 3-5 inches of rain had fallen
within the Warning area over the last 48 hours, resulting in
continued flooding along area creeks and rivers. A river gauge
along the Little Blue River at Hebron reported a stage of 14.9
feet at 1015 AM CDT, which was 1.4 feet above minor flood stage
of 13.5 feet. As a result, minor flooding is ongoing both
upstream and downstream of Hebron along the Little Blue. Also, a
gauge along the Big Sandy Creek near Alexandria reported a stage
of 15.0 feet at 945 AM CDT, which was 0.5 feet above moderate
flood stage of 14.5 feet, and is actually the highest water level
there since 2015. This flooding has resulted in the closure of
state Highway 53 just south of Alexandria. Going forward, it is
likely that water levels will start to crest and eventually
slowly fall along the Little Blue River and Big Sandy Creek
sometime on Friday, but exact timing is still a bit uncertain as
upstream water continues to work into the area from the west.
- This includes the following streams and drainages...
Dry Creek, South Fork Big Sandy Creek, Little Blue River, Little
Sandy Creek, Oak Creek, Walnut Creek, Elk Creek, Turtle Creek,
Spring Creek, Balls Branch Rose Creek, Dry Sandy Creek and Big
Sandy Creek.
- Some locations that could experience flooding include...
Hebron, Davenport, Bruning, Alexandria, Carleton, Oak and
Belvidere.
