Abstract
Severe Flooding in the Upper Midwest Leads to Rail Disruptions ...Over the past week, in areas of Iowa, South Dakota, and Minnesota, widespread flooding from record rainfall has seriously disrupted rail movements.In one case, on June 23, a BNSF Railway (BNSF) bridge connecting North Sioux City, SD, and Sioux City, IA, collapsed into the Big Sioux River.As a result-and because of track washouts in multiple locations-BNSF tracks in several subdivisions are currently out of service.The railroad has issued several temporary embargoes to "proactively manage traffic flows" in the flood-impacted areas.Also, an embargo issued by Union Pacific Railroad (UP) on June 26 impacts grain elevators, ethanol plants, soybean crush facilities, and flour mills on UP track in northwest Iowa and southern Minnesota.According to the Des Moines Register, as of June 24, UP closed track between Mason City, IA, and St. Paul, MN, and between Sioux City, IA and St. Paul, MN. ...And to Trucking/Highway Disruptions.Impacting truck movements in Iowa, South Dakota, and Minnesota, flooding has interrupted flows on Interstate 29 (I29)-a north-south route from the U.S.-Canadian border to Kansas City, MO.While I29 reopened in South Dakota, a portion has closed in Iowa (from Loveland to Council Bluffs).Many U.S. and State routes are also closed throughout the affected region, though detours are in place, where possible.On June 24, in response to impending flooding in Western Iowa, Iowa's Governor issued a disaster proclamation for Fremont, Harrison, Mills, Monona, and Pottawattamie Counties.The proclamation covers vehicles transporting corn, soybeans, hay, straw, silage, stover, fertilizer (dry, liquid, and gas), and manure (dry and liquid).During the exemption period, weight limits and permits are waived for vehicles up to 90,000 pounds gross weight.Besides expanding the gross weight limit, the waiver also covers vehicles that do not exceed the maximum axle weight limit (of 20,000 pounds) by more than 12.5 percent-as long as they comply with posted limits on roads and bridges.The waiver applies to loads transported on all highways in Iowa (except interstates). And to Barge/Waterway Disruptions.On June 23, when the water gauge reached 14 feet, St. Paul's harbor closed, and it will not reopen until at least July 8.The present forecast suggests that the water level on the Mississippi River at St. Paul will crest at 21 feet, 3 feet above major flood stage, on June 29. According toAmerican Commercial Barge Line and the United States Army Corps of Engineers, Rock Island District, lock closures may be necessary on the Upper Mississippi River, south of St. Paul, MN.With high water flowing down from St. Paul, Lock 16 (Illinois City, IL) and Lock 17 (New Boston, IL) are expected to close on July 2 and remain closed for at least a week.Lock 12 (Bellevue, IA) and Lock 13 (Fulton, IL) are expected to close on July 1 and remain closed for at least 3 days

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
