It's tornado season.
It seems Rihanna may be wrong on this one. If you are in a building with a foundation, do not evacuate. Instead, stay indoors, in an interior room and away from windows.
So, it's time to get back to the basics.
Are you ready to have a question answered that confuses millions of people each year?
What is the difference between a tornado watch and tornado warning?
Tornadoes are possible in and near the watch area. Review and discuss your emergency plans, and check supplies and your safe room. Be ready to act quickly if a warning is issued or you suspect a tornado is approaching.
A tornado has been sighted or indicated by weather radar. Tornado warnings indicate imminent danger to life and property. Go immediately to an interior room, such as a closet, hallway or bathroom, on the lowest level of the building you are in.
However, if you are about to get attacked by tornado Rihanna, then you'd better run.
