Positive visual verification. I HIGHLY RECOMMEND that you check local news sources (the localities that are known to HAVE tornadoes) and VERIFY for yourself the EXTREMELY DANGEROUS HAZARD that funnel clouds and tornadoes respresent toward human (or any) life.
IF YOU EVER see one, you will note that they are shaped just like a funnel.
IF YOU ARE ABLE to determine it's path (that is, which direction it is heading) turn 90 degrees from its path ( a right angle) and GET AS FAR AWAY AS POSSIBLE AS FAST AS IS SAFE. The storm systems that produce funnel clouds and tornadoes can drop a funnel right on top of you from five miles away from you.
If you are unable to flee, GET TO LOW GROUND AND LAY FLAT. DO NOT GET UNDER A CAR.
If you are in a house or apartment, get to the lowest floor possible, preferably a basement or storm cellar and cover yourself if possible. If a basement is not available a bathroom is often the next best choice. Take the mattress from your bed, go to the bathtub, get in it and cover yourself (or selves) with the mattress. Stay away from windows.
Do not waste time opening windows, it will not do any good and may even make the situation worse.

No. Stratus clouds are low level, usually flat clouds that can bring rain or snow but usually do not indicate hazardous weather. A funnel cloud is a rotating downward projection of a cumulonimbus that is often cone shaped.
