Upcoming storm for sat. night

I might not be online saturday. We're suppose to get another severe thunderstorm this weekend. And the weather man said we are in the yellow. I don't know if that's severe or high risk.  But he did mention, strong wind, hail, and iso. tornado's.  I'm not taking any chances on being online when the storm comes thru. Don't want my computer to get fried!!! I hope everyone's weekend will turn out to be good!
