Severe solar storm could stress power grids even more as US deals with major back-to-back hurricanes

Space weather forecasters say a severe solar storm heading to Earth could stress power grids even more as the U.S. deals with major back-to-back hurricanes. A severe geomagnetic storm watch has been issued for Thursday into Friday. The National Oceanic and Atmospheric Administration said Wednesday it has notified operators of power plants and orbiting spacecraft to take precautions. It also alerted the Federal Emergency Management Agency about possible power disruptions. Experts do not expect the storm to surpass the extreme solar storm that hit Earth in May. That one was the strongest to strike in more than two decades.
