If you mean a twenty percent chance of precipitation, yes. In some cases a system will produce isolated supercell thunderstorms which have the potential to produce tornadoes. While most places would not see any rain from these storms, there would be the potential for tornadoes.
Usually less than five minutes and often just a few seconds. Strong tornadoes can last for over 20 minutes, sometimes over an hour. The longest a tornado has been known to last was three and a half hours.
During a tornado, the air pressure can drop significantly. It is not uncommon to see pressure drops of 10-20% below normal levels, which can correspond to pressures around 28 to 30 inches of mercury (950-1010 millibars).
To make a 20% dextrose solution, you need to dilute the 70% dextrose solution with water. You need to use 178.57 ml of the 70% dextrose and 321.43 ml of water to make 500 ml of 20% dextrose solution.
An F5 tornado typically lasts for over half an hour, and sometimes over an hour.
Tornadoes typically form at speeds ranging from 10-20 mph as part of a severe thunderstorm. Once they develop further and intensify, tornadoes can reach speeds exceeding 300 mph in extreme cases.

A tornado in 1971 at Kin Kin, in Queensland claimed three lives. In spite of what many people seem to think, tornadoes DO occur in Australia, around 20 per year on average.
10 to 20 mph would be a slow moving tornado. A typical tornado travels at 30-35 mph.
Yes. There actually was a tornado in Edmonton about 20 years ago.
The most recent F5/EF5 tornado was the Moore, Oklahoma tornado of May 20, 2013.
20% of 20% is 4% (=0.04)
20 percent out of 100 is 20 percent. 100 percent is all you can have. 20 is one fifth. 5x20=100
12 percent of 20 percent is 0.024 or 2.4%
the normal precipitation is 16-20 inches of rain.
7 of out 20 in percent is (7/20)*100 = 35 percent.
The Moore, Oklahoma tornado of May 20, 2013 injured 377 people.
20 percent of 80 percent = 0.16 or 16%
