St Joseph County Emergency Management has been assessing damage in a swath from roughly south of Centreville northeast to north of Colon and to the St. Joseph/Branch county line. Branch county EMA officials and the NWS completed the survey of damage in NW Branch county from Havens Lake northeast to south of Union Lake. The strongest damage found in Branch county was consistent with EF2 damage and estimated winds of 130 mph. Since the track is not finalized with damage in St. Joseph county, the final rating and track details will not be released at this time. A survey team plans to assess St. Joseph county on May 9th.
How are tornadoes classified?
The rating and the strength of tornadoes are determined by storm damage and wind speed, which is placed on the Enhanced Fujita (EF) Scale.
