Winter Storm Riley caused a variety of problems. First off, it is now meteorologically speaking, springtime…so this storm system was a nor’easter to remember. Parts of northeastward Pennsylvania and southeast New York State have reported exceptional (not necessarily a record) snowfall for March.
The way that W.S. Riley had to do with the Grand Solar Minimum is the fact that in the Washington D.C. metro area and Delmarva region, this storm system brought high winds starting around 9:30 PM last Monday. The wind blew at 29 miles per hour constantly! The highest wind gust was 80 miles per hour in Sterling, VA around noon.
You may ask, okay, but why does this mean that the GSM is into play? If you ask the young and the elderly, they all told me they have never seen the wind blow so hard for so long. You have to look back at records from the 1700’s and 1800’s to find these hard winds. If you look at symptoms of the Grand Solar Minimum, high, long-lasting winds are one of them. There has been high winds reported in Australia as well as other places as well since late 2017.
