Severe Weather Preparedness Week in South Carolina
South Carolina Severe Weather and Flood Safety Week is March 5-11, 2023
A statewide tornado drill is scheduled for Wednesday, March 8 at 9:00 a.m
The South Carolina Emergency Management Division (SCEMD) and the National Weather Service are co-sponsoring this week to remind people that severe storms, tornadoes and flash floods pose significant risks in South Carolina and people need to take proper safety precautions.
SCEMD and the National Weather Service promote awareness of the risks associated with severe weather, including tornadoes and floods, and actions to help keep people safe.
A highlight of the week will be the annual statewide tornado drill. Trainings are conducted in close coordination with the South Carolina Broadcasters Association. The state superintendent of education encourages schools statewide to participate. The National Weather Service will use the Routine Weekly Test (RWT) product on NOAA Weather Radio when conducting the training. The “RWT” code will activate weather radios to alert tones in the same manner as the routine weekly test every Wednesday, and these radios will broadcast the drill message.
Training will take place on Wednesday, March 8 at 9 a.m. Public schools, state and local emergency management, the South Carolina Broadcasters Association and others will participate in this annual event. The purpose of the training is to test communications systems, safety procedures, mitigation processes, etc.
