Cat 3 is basically strong thunderstorm RFD at peak downdraft strength. And hurricanes are bands of supercell storms all wrapped in one system feeding off of each other. Only difference is that the most powerful Plains thunderstorm downdrafts might last about 0.5 hours to around 45 minutes max if you are stationary. With a hurricane you will be getting these effects sustained for 6-10 hours.
