On weather maps, these readings are represented as a blue “H” for high pressure or a red “L” for low pressure.
What does dark blue mean on a weather map?
Regions of light and dark blue indicate regions of lighter precipitation while areas of red and purple indicate strong, to occasionally severe thunderstorms.

Can a f5 tornado pick up a tank?
I read reports of devastation in an EF5 Tornado defined as one with winds to a maximum of 324 MPH… My CLEAR conclusion reading the following reports is that you could NOT take a tank into an EF5 Tornado without the very real risk of it being tossed and damaged or destroyed, including killing the tank crew inside of it.
