Four people were killed by tornadoes in Mississippi on Saturday.
A "tornado risk" continued for Southern Florida, the National Weather Service said, as it warned of damaging winds and hail.
The Georgia Emergency Management Agency said in a news release that the 14 victims were in the southern Cook, Brooks, Dougherty and Berrien counties.
Most of the deaths occurred in Cook County, when a mobile home park was apparently struck by a tornado, reports the BBC.
Storm prediction warning for southern Florida
NWS Storm Prediction Center Norman OK 1118 PM CST Sun Jan 22 2017 Areas affected...
Southern Florida Concerning...Tornado Watch 24... Valid 230518Z - 230715Z
The severe weather threat for Tornado Watch 24 continues.
SUMMARY...A broken band of strong storms continues moving slowly southeast across southern Florida. Isolated severe/tornado risk continues.
DISCUSSION...Latest radar loop reveals roughly 20 kt southeastward progression of the band of storms which now extends from Indian River County to Collier County, while individual cells (some of which continue to exhibit weak low-level rotation) move quickly northeastward.
Extrapolation of current line movement suggests that the band will clear the coast/keys by 10-11 Z. Until the line moves offshore, risk for locally damaging winds/hail and a tornado or two will continue, as the pre-frontal environment (per evening raobs and the latest VWPs) remains supportive of updraft organization/rotation. ..Goss.. 01/23/2017
