Hurricane Sally is closing in on the US Gulf Coast, threatening several southern US states including Florida, Mississippi and Alabama.
Sally is crawling at two miles per hour after growing to a category two storm on Monday.
It is expected to intensify before making landfall early Wednesday.
The National Hurricane Center said Sally could bring historic flooding and extreme life-threatening flash flooding is likely.
The storm is already drenching parts of the US Gulf Coast as hurricane conditions are expected along the Mississippi and Alabama coastlines and north-western Florida.
