The mayor of Tampa issued a stark, ominous warning on Monday evening: If residents in an evacuation zone don’t follow orders as Hurricane Milton barrels toward them, certain death is imminent.

Video filmed Oct. 7 shows backed-up traffic on Interstate 75 outside the Tampa area as Florida residents began to evacuate ahead of Hurricane Milton.

Mayor Liz Alpert of Sarasota, Fla., said that ahead of Hurricane Milton’s landfall evacuations are underway with many people taking storm preparations seriously. Milton is expected to bring 10 to 15-foot storm surges across the Florida coast.

The center of Hurricane Milton could come ashore Wednesday in the Tampa Bay region, which has not endured a direct hit by a major hurricane in more than a century. Scientists expect the system to weaken slightly before landfall,
