As Tropical Storm Isaias neared Florida's east coast Saturday, Gov. Ron DeSantis (R) urged communities to "remain vigilant and be prepared for heavy rain, strong winds and potential flooding."

The state of play: After pummeling the Bahamas and parts of Puerto Rico and the Dominican Republic as a Category 1 storm Friday, Isaias was downgraded from a hurricane Saturday evening. But the National Hurricane Center (NHC) said Isaias was expected to "regain hurricane strength" overnight.
