Massive storm hits US state Florida a

Residents of mainland Florida are bracing for Hurricane Irma to hit, as conditions in the south of the state deteriorate, BBC report.

The category four storm with sustained winds up to 130mph (209km/h) moved away from the Florida Keys and should make landfall on the west coast in hours.

High winds and storm surges are affecting the Miami area, but Florida Governor Rick Scott said he was “very concerned” about the west coast.

More than 1m homes are without power.

More than 6.3 million people in Florida were told to evacuate, with warnings of a “life-threatening” storm surge.

Irma has already devastated parts of the Caribbean with at least 27 deaths.

What is happening in Florida?

Extreme winds and storm surges continued in the Lower Florida Keys area, which includes Key West.

All residents had been ordered to leave. Some surges could reach 15ft (4.6m).

One official had warned staying on the islands would be “almost like suicide”.

Media reports say a man was killed on Saturday in the Keys when his pick-up truck crashed into a tree as the storm gathered pace.
