TALLAHASSEE, Fla. (AP) — Authorities and residents in Florida are keeping a cautious eye on Tropical Storm Ian as it rumbles through the Caribbean, expected to continue gaining strength and become a major hurricane in the coming days on a forecast track toward the state. Gov. Ron DeSantis has declared a statewide emergency, expanding an order from Friday that had covered two dozen counties. He is urging Floridians to prepare for a storm that could lash large swaths of the state. Some residents have begun stocking up on supplies such as water, plywood and generators. President Joe Biden has also declared an emergency for the state.
