Lightning questions
Why are there no single strike dots?
No free official source publishes individual strikes for the US or Canada. PerilRadar shows official density maps instead of using community data that forbids commercial use.
When thunder roars, what should I do?
Go indoors. The National Weather Service advice is simple: when thunder roars, go indoors, and wait 30 minutes after the last thunder before going back out.
