Residents in the affected counties should prepare for potentially damaging winds, heavy rainfall, and power outages. Wind speeds could reach up to 80 mph, posing risks to structures, trees, and power lines. The FAA's ground stops at major airports may lead to travel disruptions. The NWS warns that the storm's winds could be as destructive as those of a tornado, emphasizing the need for immediate precautions. Flooding in low-lying areas is also a concern due to the anticipated heavy rainfall.
