Several layers of protection exist to buffer people during severe weather through both traditional and tech-savvy methods.
Waves of warnings are issued through the media, websites, phone messages and wailing sirens. None of these alerts can be 100 percent effective when a storm transforms from a red area on the radar map into a twister on the ground within a matter of seconds.
The ruthless and stealthy nature of severe weather means people must remain vigilant and be proactive in seeking refuge from everything to lightning and flooded roadways to hail and winds exceeding 100 mph.
“If we’re under a tornado watch, then people don’t need to be in a vehicle. Visible warning signs would be if they start seeing traffic signs moving back and forth, turning and twisting around, or trees are doing the same thing,” said Daphne Ellison, spokeswoman for the Limestone Emergency Management Agency.
Turbulent weather can be tracked through televised reports, weather radios, ham radios or even word-of-mouth if phone service becomes unavailable.
Limestone has 73 functioning weather sirens, including 27 operated by the EMA, and 47 by the Tennessee Valley Authority.
Lightning likely deactivated the county’s siren at Miller Lane and Alabama 251 in Ardmore prior to the monthly testing conducted on March 11. The county will seek to replace the siren through an insurance claim.
The EMA, which has helped train storm spotters for at least 20 years, has a dozen spotters who volunteer at the agency, a mobile command center equipped with four satellite phones and a backup generator.
Smartphone users can access the NWS mobile website at www.mobile.weather.gov, or tap applications such as the Tornado App developed by the American Red Cross.
The National Weather Service can already send phone alerts to smartphone owners, and a weather app is being developed, said Stephen Latimer, a meteorologist with the NWS in Huntsville.
He said an app produced by the NWS or the Federal Emergency Management Agency has legal ramifications and red tape to sort through before being approved.
“We’re different than most government agencies, with perhaps the exception with FEMA because they issue bulletins. We have a lot of different information coming through — radar data, warnings and advisories — and our information changes so rapidly,” Latimer said.
