Guest requesting full refund due to rain

[Mindy Nicol]

A guest just contacted me asking for a full refund for her week’s stay. She was due to arrive today. She claims there is rain in the forecast for the next 5 days and also that it is too dangerous to drive. My cancellation policy is moderate. I don’t see any rain in our area today when she was planning to drive. No tropical storm, cyclone or state of emergency has been issued. There are really just a couple of rainstorms moving around the state at the moment. I personally have no problem driving in the rain if there was any. I don’t understand why she would cancel an entire 7 night stay when the rain may happen in a short period. I don’t know if she has travel insurance but will ask! Any other tips for this?
