The National Weather Service office in Huntsville added four new tornado tracks, all in Marshall County, to raise the total to 37 separate tornadoes in North Alabama.
The Huntsville office on Friday also upgraded the deadly EF-4 that struck DeKalb County, raising the estimates to an EF-5. That's the most powerful level on the Enhanced Fujita scale, indicating winds exceeding 200 mph. The only other EF-5 on April 27 ran along the ground from Hackleburg to Madison County.
The National Weather Service office in Birmingham has also identified 30 tornadoes on April 27. Six of those tornadoes continued into North Alabama and were surveyed by both offices.
