Hurricane Harvey is drowning southeastern Texas for the fourth day, putting a vast area under feet of water. Experts say Harvey has been stuck longer in one place than any tropical storm in memory. That is just one of the hurricane’s extremes; the storm is off the charts by many measures. Scientific American wanted to learn why, and we asked meteorologist Jeff Masters for help. Masters is the co-founder of Weather Underground, a website that meteorologists nationwide go to for their own inside information about severe weather. Masters also wrote a fascinating article on why the jet stream is getting weird.
