Florida Gov. Rick Scott has visited Puerto Rico six times since the island was ravaged by Hurricane Maria last year. He's brought aid, advice, and on one trip, even a delegation of utility providers to consult on how best to restore the island's tattered power grid.

In the Virgin Islands, a steep drive up a mountainside in St. Thomas takes you to a community called Anna's Retreat. At the very top of the hill there's a house owned by Hophni Martin. An affable man, he laughs as he explains that his name comes from scripture.

"You'll find it in 1 Samuel," he says. "I'm not a Bible man, but my father was. He gave us the name."

With the beginning of the Atlantic hurricane season, residents in coastal areas throughout the Southeast are once again being urged to have a plan ready in case they have to evacuate.

After last year, it's a message that carries some weight. In the days before Hurricane Irma struck Florida last September, nearly 7 million residents left their homes to seek shelter and safety elsewhere. Since then, emergency managers and researchers have been studying the lessons of the largest hurricane evacuation in U.S. history.

Prosecutors have released three cellphone videos recorded by Nikolas Cruz, in which he described his plans for the shooting at Marjory Stoneman Douglas High School in Parkland, Fla. Some of the videos appear to have been recorded the day of the shooting.

At Mote Marine Lab's Center for Coral Reef Research and Restoration in the Florida Keys, Joey Mandara is like a baby sitter. But instead of children he tends to thousands of baby corals, growing in large, shallow tanks called raceways.

Mote has been doing this work for five years, raising corals from embryos into adult colonies, then planting them on Florida's reefs. Now, the emergence of a new, debilitating coral disease makes his work more important than ever.
