The National Weather Service offices in Fort Worth and Shreveport were out surveying damage tracks again today. The team from Fort Worth found two additional tornado tracks. In addition, we’ve now included two tornado tracks from near Lindale and Mineola. Finally, the Eustace tornado that went just west of Canton (the first of several tornadoes to impact the city) was upgraded to an EF-4 with maximum sustained winds estimated to be near 180 MPH. Eight tornadoes have been confirmed and additional damage surveys will be conducted on Tuesday. These survey results are subject to change. Please note that the Lindale and Mineola tornado tracks are not included in the graphic below.
