Media captionStorm Michael’s trail of devastationOne of the strongest storms in recorded history to hit the US has battered north-west Florida, flooding homes, washing out beaches and snapping trees.
Rescue services are beginning to assess the full impact of Hurricane Michael, which made landfall on Wednesday afternoon as a category four storm with 155mph (250km/h) winds.
Two people, including a child, were killed by falling debris.
Having weakened to a tropical storm, Michael is on its way to the Carolinas.
Storm-surge warnings are still in place, the US National Hurricane Center says, and residents across the southern US have been warned of the continuing danger from downed powerlines, flash floods and landslides.

There are fears for people who ignored evacuation warnings in some of the areas now flooded.
Hundreds of thousands of homes and businesses were left without electricity in Florida, Alabama and Georgia.

How powerful was Michael when it landed?
Michael made landfall near Mexico Beach, Florida, at around 14:00 (18:00 GMT) on Wednesday.
It ranks among the most powerful hurricanes to hit the US in terms of wind speed and barometric pressure, comparable to Hurricane Andrew in 1992.

Michael was so strong as it swept into Florida that it remained a hurricane for hours as it moved further inland, before being downgraded to a tropical storm.
Its rapid intensification caught many by surprise, although the storm later weakened.

Hurricanes

A guide to the world’s deadliest storms

Hurricanes are violent storms that can bring devastation to coastal areas, threatening lives, homes and businesses.

Hurricanes develop from thunderstorms, fuelled by warm, moist air as they cross sub-tropical waters. Warm air rises into the storm.

Air swirls in to fill the low pressure in the storm, sucking air in and upwards, reinforcing the low pressure.

The storm rotates due to the spin of the earth and energy from the warm ocean increases wind speeds as it builds.

When winds reach 119km/h (74mph), it is known as a hurricane – in the Atlantic and Eastern Pacific – or a typhoon in the Western Pacific.

“Everybody has a plan until they get punched in the face. Well, we’re about to get punched in the face.” Florida Mayor Bob Buckhorn, ahead of Hurricane Irma (2017)

The central eye of calmer weather is surrounded by a wall of rainstorms.This eyewall has the fastest winds below it and violent currents of air rising through it.

A mound of water piles up below the eye which is unleashed as the storm reaches land. These storm surges can cause more damage from flooding than the winds.

“Urgent warning about the rapid rise of water on the SW FL coast with the passage of #Irma’s eye. MOVE AWAY FROM THE WATER!”Tweet from the National Hurricane Center

The size of hurricanes is mainly measured by the Saffir-Simpson scale – other scales are used in Asia Pacific and Australia.

Winds 119-153km/hSome minor flooding, little structural damage. Storm surge +1.2m-1.5m

Winds 154-177km/hRoofs and trees could be damaged. Storm surge +1.8m-2.4m

Winds 178-208km/hHouses suffer damage, severe flooding Storm surge +2.7m-3.7m

Hurricane Sandy (2012) caused $71bn damage in the Caribbean and New York

Winds 209-251km/hSome roofs destroyed and major structural damage to houses. Storm surge +4m-5.5m

Hurricane Ike (2008) hit Caribbean islands and Louisiana and was blamed for at least 195 deaths

Winds 252km/h+Serious damage to buildings, severe flooding further inland. Storm surge +5.5m

Hurricane Irma (2017) caused devastation in Caribbean islands, leaving thousands homeless

“For everyone thinking they can ride this storm out, I have news for you: that will be one of the biggest mistakes you can make in your life.” Mayor of New Orleans Ray Nagin ahead of Hurricane Gustav, 2008
