April 27 2011. I had always watched weather, but this got me more into that and being a Ham Radio operator. I wanted to before but after hearing the stories how Ham Radio was used to help the local agencies with communications, I went and got my license.
Snowmaggeddon 2014. My wife worked at the Madison Hospital during this, and still had to be at work. It took us an hour to drive there because the roads were iced over. Luckily I had a 4 wheel drive truck to help out some.
The 2010 Nashville flood. Opry Mills closing for almost 2 years and the Grand Ole Opry sustaining major damage. The Cumberland River was at its highest point since the Dam was put in place in the 60's
Sandy in 2012
The Hawaii Volcano Kilauea
The California Wildfires of 2017
These are the ones that bring the most memories to me for that decade.
I had forgotten Sandy til you mentioned it, though I was living in upstate NY at the time; Irene was intense there, too. Odd how something that bad passes out of your thoughts over time.
The tragedies of 2011 are something else. I hope nothing like that happens again for a long time.
I wasn't there then but I was in West Central Alabama for the 2005 hurricane season - they just kept coming!
Personally, it's a decade where I've experienced the majesty of Southern weather - every summer sunset, for example, or seeing cumulus towers collapse over Mississippi fields - to my current setting. Love it, even the rain, but even thunder hardly ever happens!
That's quite a range.
