Note:  Prior Years refers to the years 1950 – 2012, the years of the most accurate tornado data.  May 31 tornado fatalities could be increased.  The tally we use is currently 9, which may be too low.  The tally is currently at 20, according to NewsOK.com, but some of these fatalities may be due to flooding rather than tornadoes. The Storm Prediction Center is explicit about using deaths caused only by tornadoes in its data rather than deaths caused by flooding, so we are being cautious in keeping the May 31 death toll at 9 for the time being. Tornado statistics are in beta and are subject to change.

El Reno, OK Tornado Dramatically Wider than Other Recorded F5/EF5 Tornadoes

The May 31, 2013 El Reno tornado was the widest ever recorded at 2.6 miles wide. It’s worth showing how much wider the tornado was than any other EF5 tornado:

Note: “0.2” represents tornadoes that were 0.01 – 0.20 miles wide, “0.4” represents tornadoes that were 0.21 – 0.40 miles wide, and so forth.  The Moore, OK 2013 tornado was 1.3 miles wide, so it goes in the bin labelled “1.4”.

Note:  “Prior Years” refers to the years 1950 – 2012, the years of the most accurate tornado data.  May 31 tornado fatalities are likely to be increased.  The tally we use is currently at 9, which is likely too low.  The tally from the tornadoes and flooding is currently at 18, according to media reports. However, the Storm Prediction Center is explicit about using deaths caused only by tornadoes in its data rather than deaths caused by flooding, and the exact breakdown isn’t clear yet. Tornado statistics are in beta and are subject to change.

Washington Bridge Collapse: 71,000 Vehicles Use Bridge Daily

According to data reviewed by AnalysisWire, 71,000 vehicles used the now-collapsed Skagit River bridge daily in 2012. Nearby monitors suggest that there was substantial local usage of the bridge, as traffic monitors before and after the bridge show lower traffic than the monitor closest to the bridge (the second monitor listed below). Thus, the loss of the bridge will be felt acutely in Mt. Vernon in addition to the regular travelers on I-5.

Mile Description Avg. Daily Traffic, 2012
227.73 AT SR 538 BRIDGE 54000
228.17 AFTER RAMP SR 538 71000
228.87 AT GEORGE HOPPER RD 58000
