The Week in Review 2




In Week in Review 2, we find that the FBI has finally released the full crime numbers for 2017 for all cities. How did Columbus fare? Well, it was a decidedly mixed bag. Total murders were their highest ever, at 143, but the rate fell quite short of the record set back in 1991. So far for 2018, murder is behind 2017’s rate by about 22%, so it’s a good improvement, but still not even close to where it should be.

Other violent crime figures 2016 to 2017
-Rape continued its multi-year rise in the city, reaching 919 incidents. This was a 6% increase over 2016.
-Assaults were up 4% over 2016, but in the context of still being one of the lowest totals in the past 30 years.
-Robberies were down almost 8.5% over 2016.
-Despite the rises in most types of violent crime, the drop in robberies meant overall violent crime dropped by about 0.5%.
Property crime figures 2016 to 2017
-Burglaries were down more than 8%.
-Larceny thefts were down about 2.9%
-Motor vehicle thefts were up 17.6%, so not a good trend, but still less than half the rate it was 15-20 years ago.
-Overall property crime was down about 2% versus 2016.

And if you think this year’s been particularly wet, you are right! Through October 1st, Columbus is having its 3rd wettest year on record. Only 1882 and 1890 are ahead of 2018 at this point, and by barely 1″. 2018 at this point is running almost 14″ above normal.
Top 10 Wettest Years Through October 1st
1. 1882: 44.55″
2. 1890: 43.56″
3. 2018: 43.31″
4. 1979: 42.17″
5. 2003: 41.58″
6. 2011: 41.12″
7. 1990: 39.10″
8. 1949: 38.54″
9. 2004: 38.46″
10. 1996: 37.46″
It is surprising how many recent years are on this list. Still with 3 months to go, the pattern could break, but it’s very unlikely that 2018 doesn’t end up in the top 10. Here are the top 10 wettest full years.
1. 2011: 54.96″
2. 1990: 53.16″
3. 1882: 51.30″
4. 1890: 50.73″
5. 2004: 49.27″
6. 1979: 49.17″
7. 2003: 49.03″
8. 1883: 48.88″
9. 1881: 46.99″
10. 2017: 46.61″

I guess it could always be worse…
The week in review 2 Columbus, Ohio




Summer of Rain 2015

Summer of rain

This summer has been wet… very wet. Rain has fallen on far more days than not, and cloud cover has hung thick and heavy in what are historically much sunnier months. To top it all off, temperatures have been somewhat below normal.

How wet has the Summer of Rain 2015 been up through today? Meteorological summer runs June 1st-August 31st, and today makes the midpoint of that period, so I thought it would be a good time to check in and answer that question.

Here are the top 10 wettest summers through yesterday.
1. 1958: 12.54″
2. 2008: 11.68″
3. 1990: 10.93″
4. 2015: 10.66″
5. 1949: 10.40″
6. 1973: 10.23″
7. 1917: 10.06″
8. 1928: 10.02″
9. 1937: 9.75″
10. 1969: 9.38″

So 2015 is running the 4th wettest. It looks to be dry the next few days before more thunderstorms and rain return, so 2015′s position may end up rising.

What are the wettest full summers of all time? A few of the above years went on to be in the top 10, but not all.
1. 1958: 22.02″
2. 1979: 20.92″
3. 1995: 19.85″
4. 2003: 19.39″
5. 1969: 19.09″
6. 1915: 18.92″
7. 1992: 18.44″
8. 1973: 17.81″
9. 1989: 17.45″
10. 1949: 16.54″

Summer 2015 needs about 6″ more to reach into the top 10 wettest summers, which at the current pace is more than possible.
