Hurricane Irma strengthened and made landfall in Cuba as a Category 5 storm, as millions of Florida residents were ordered to evacuate after the storm killed 22 people in the eastern Caribbean and left destruction in its wake.

Irma ravaged small islands in the northeastern Caribbean, including Barbuda, Saint Martin and the British and US Virgin Islands, flattening homes and hospitals and ripping down trees.

But even as they came to grips with the massive destruction, residents of the islands faced the threat of another major storm, Hurricane Jose.

Meanwhile, Hurricane Katia appeared to weaken as it headed towards Mexico.
