"Is it a fact or a myth that a tornado will skip over a body of water? Someone told me that they were out in a boat and weren't worried about a tornado warning because they'd be safe on water. I'm not sure that's a good idea! Thank you!"
Nancy Hartman, Burnsville
Nancy - your gut is correct. A lake, river (or valley) won't deter a tornado, especially a large tornado. A tornado is a process, not an object; the larger dynamics and wind inflow into a severe thunderstorm drive the intensification or weakening of a funnel, not the surface the vortex passes over. I've seen numerous instances of a tornado passing over water, transitioning to a waterspout, then back to tornado as it passes over land again. Another important point: severe thunderstorms capable of tornadoes usually produce intense lightning; another reason you don't want to be on a lake (or beach). Thanks for a great question/observation.
Kae- A good place to start is the Twin Cities Chapter of the American Meteorological Society, which has frequent meetings with interesting topics/guest speakers and a chance to network with local weather enthusiasts and meteorologists. Good luck!

The massive wildfire is now 80 percent contained according to a state fire spokesman. The Rim Fire’s southeast flank in Yosemite National Park is expected to remain active where unburned fuels remain between containment lines and the fire."

USAA totaled some 4,000 customer vehicles that had been damaged, but officials for the San Antonio-based insurer now admit that some vehicles that had been totaled instead were resold and put back on the road. USAA had earmarked 174 vehicles to be sold for parts only, but has found that some were fraudulently given clean titles."
