Updated tornado survey data

The NWS office in Indianapolis has updated part of their survey about the tornado which had touchdowns in Delaware County and Jay County Indiana. Here’s the latest text update. The NWS is estimating a 400-yard wide path across that area and winds up to 134 mph which is the same enhanced Fujita scale estimate in Mercer County, Ohio. Keep in mind that the EF scale is a damage scale which is estimated after the tornado touchdown. Survey crews go in and look at the damage and take several factors under consideration to estimate wind speeds which caused the damage.  Here’s the new text data update Tuesday, November 7.
