I’ve never been to FL. For most the automatic assumption is hot and humid all the time. It takes a while to remember that it can get damn cold there.
If I'm reading this chart correctly, the temperature was in the low 60's when the shooting happened . . . sweatshirt weather.
Night plus rain plus wind equals cold - even in Florida. Went catamaranning one summer night some time back - was soaked to the bone for 3 or 4 hours. I thought I’d never warm up... Catamarans are daytime crafts in my book...
