Give me 2 precautions you should take during a thunderstorm.

In Georgia, the temperature is 75 degrees F and the relative humidity is 100%. In North Dakota the temperature is 40 degrees F and the relative humidity is 100%. Is the amount of water vapor in the air over Georgia and North Dakota the same? Why or why not?
The warmer the air is, the more water vapor it can hold, so the air over Florida contains more water vapor than the air over North Dakota.
The relative humidity is the same percent for both because the air is holding the most water vapor it can hold at that particular temperature.
