I just downloaded Carrot Weather for iOS and installed it on my Apple Watch as well. Everything works as advertised and the voice is very “Siri-like.” I read that precipitation and severe weather alerts can be received, but you need to have Carrot Weather for OS X installed and running. I purchased that app for my iMac. We haven’t had any severe weather warnings yet, so I can’t report on how that function works. I’m a real weather junkie, and have tried just about every weather app for iOS, and I really love this one!
