I just heard on the news one tornado spotter saw a tornado that was as wide as 2 football fields! What's that in miles/meters?[/quote]
that would be in yards.
Severe weather? Southern Plains - March 29/30 - MDT risk

one football field is 100 yards wide...so two would be 200 years wide. So, if we do the math, we find that...Cyclenall wrote:CrazyC83 wrote:250 mph? That would be an EF5 and it would be a repeat of May 3, 1999...
Even if that tornado was 250 mph, it would still not compare to the May 3rd, 1999 tornado which had winds of 318 mph...just shy of being the first F6.

2 football fields = 200 yards = 183 meters = About 600 feet = .11 miles (.18 kilometers)
So basically this tornado was about 1/10th of a mile wide (or about 1/5th of a kilometer wide). Decent size, but really nothing extremely large.

Thanks for figuring the math out. For some reason I thought 2 football fields was quite large but really it's nothing when you put it into miles.

TWO HOMES SEVERELY DAMAGED.
Could have been an unseen tornado.
Yupp, possibly.
I think this report is from the same storm.
AT 459 PM CDT...NATIONAL WEATHER SERVICE METEOROLOGISTS DETECTED A
DEVELOPING TORNADO. THIS TORNADO WAS LOCATED NEAR LORENA...OR ABOUT
7 MILES SOUTHWEST OF HEWITT...MOVING NORTHEAST AT 35 MPH. THE
PUBLIC REPORTED TREES UPROOTED NEAR MOODY WITHIN THE LAST 15
MINUTES.
