Risk of Illinois dam breach is under control after once-in-a-century rainfall, officials say    

https://www.cnn.com/2024/07/16/us/nashville-illinois-dam-break/index.html

            Washington County was under a flash flood warning until 4:30 p.m. CT after the region received over 5 inches of rain in six hours, according to radar estimates from the National Weather Service office in St. Louis.          

          That level of rain approaches 100-year rainfall frequency – the type of downpour statistically likely to happen only once every century – according to weather records.      

            Extreme rainfall events like these are becoming more common, and they illustrate the effects of climate change. As the planet warms from fossil fuel pollution, the atmosphere is able to hold more moisture, which can then be released as intense rainfall.    

++++++++++++++

Amount of rain after climate change = 5 inches

Same weather pattern 100 years ago = 4.7 inches

++++++++++++++++++++

 

For the umpteenth time:

It really boils down to this, once again(Cliff Mass can be counted on as an elite source for using objective, authentic science)

The GoldenRule

 Considering the substantial confusion in the media about this critical issue, let me provide the GOLDENRULE OF CLIMATE EXTREMES. Here it is:

The more extreme a climate or weather record is, the greater the contribution of natural variability.

Or to put it a different way, the larger or more unusual an extreme, the higher proportion of the extreme is due to natural variability.   

+++++++++++

These people cherry pick every extreme, as if there were no extremes in the past and tie them to climate change.

However, in this case, at least they used 1 in 100 years instead of 1 in 1,000 years!

This last rain was just over 5 inches(in an isolated spot). How does that compare to the heaviest short term rain event in IL history?

Heaviest Reported 24-Hour Rainfall in Illinois – A Look Back at Records

The previous record 24-hour rainfall was 16.54 inches set on June 14-15, 1957, near Millstadt in St. Clair County (near East St. Louis), according to a Water Survey report. While the 1996 event occurred over 24 hours, the 1957 storm lasted only 12 hours – essentially producing the same amount of rain in less than half the time.

But here is the next interesting fact. Before the 1957 storm, the previous record 24-hour rainfall was 10.48 inches on October 1, 1954 set at Aurora, IL.

So Aurora held the statewide record 24-hour rainfall for about three years until it lost out in 1957 only to regained the crown in 1996, where the record remains to this day. I’m not sure if they deserve the golden rain gauge or the golden sump pump award for this honor.
