Hereâs why I chose the NASM certification! Did you need any sort of background related to the field going into the program? Nope, you just need to make sure that you have a current CPR and AED certification before you take the exam. How long does your certification last before you have to renew it?
Tornado Warning. This is issued when a tornado is indicated by the WSR-88D radar or sighted by spotters; therefore, people in the affected area should seek safe shelter immediately. They can be issued without a Tornado Watch being already in effect. They are usually issued for a duration of around 30 minutes.
If your area is under a tornado warning, would you know what to do to stay safe? You may only have a few minutes to get to safety. Knowing what actions to take when a tornado threatens your area will make you a Force of Nature and is an important step in building a Weather-Ready Nation.For more info. on tornadoes and tornado safety, see: http://www.spc.noaa.gov/faq/tornado/.f your area is under a tornado warning, would you know what to do to stay safe?
