What EF1 means. On the Enhanced Fujita scale, EF1 is moderate damage: roofs badly stripped, mobile homes pushed off foundations or overturned, windows broken, consistent with estimated gusts of 86–110 mph. The rating comes from a survey of the worst damage after the storm, not from a wind measurement, so it says as much about what the tornado hit as about how strong it was.

What the National Weather Service wrote

A National Weather Service survey team found that an EF1 tornado with maximum wind speeds of 95 MPH and a maximum path width of 100 yards began along the Highway 441 Bypass on the southern edge of Irwinton where several trees were blown down. The tornado moved east-northeast crossing Bear Camp and Water Fork Roads before meeting up with and travelling along Highway 57 into Toomsboro downing several more trees along the way. [01/21/17: Tornado #15, County #1/1, EF1, Wilkinson, 2017:016].

The wider storm

Throughout the weekend of the 21st and 22nd, persistent southwesterly upper-level flow brought a series of strong short waves across the region. The atmosphere over central Georgia was unseasonably warm and unstable with strong low and mid-level shear. The first short wave generated a wave of severe thunderstorms across central and south Georgia through the morning and into the afternoon of the 21st that produced numerous tornadoes. Twenty three tornadoes were confirmed in the WFO Peachtree City warning area with 27 total tornadoes confirmed in the state of Georgia, both records for the number of tornadoes in a single day. A second, stronger short wave swept through during the late morning and afternoon of the 22nd bringing another round of severe weather to central and south Georgia. Additional tornadoes confirmed brought the 2-day total to 27 for the WFO Peachtree City warning area and 41 for the state of Georgia, both a record number for a 2 day period.

Began near Irwinton (32.7970, -83.1700).
