Q: I watched the weather report on TV. He said it would be cool, slight breeze, with absolutely no mention or indication of rain. I dressed and planned accordingly, wound up getting drenched by a lot of rain, got a bad cold, had to be off my feet for a week, and lost work time. Is there a claim that can be made for that false weather report?

A: Sounds like your claim would be for personal injury. The elements of such a claim are that the weather person had a duty to you to act in a careful manner (often referred to as a “reasonable person” standard). In addition, he or she breached that duty which proximately caused your damages. Applying this to the weather report: Is what you heard the only weather report that day that was inaccurate? Can you prove the weather person acted in a negligent manner? What information did he or she have on which the report was based? Then, what caused your cold? Being wet? Not going inside quickly enough? Is it flu season and a lot of folks are getting ill?
