Washington: Millions of people, including thousands of Indian-Americans, in Florida braced for "life-threatening" Hurricane Irma which hit the state's southern islands on Sunday as a category four storm after leaving a trail of destruction across the Caribbean.
Hurricane Irma's eyewall slammed into the lower Florida Keys on Sunday, lashing the island chain with fearsome wind gusts.
The eye of the Category 4 storm was 24 kilometers southeast of Key West, bringing winds up to 130 miles per hour and threatening dangerous storm surges.
More than 6.3 million people were told to evacuate Florida, with warnings of a huge storm surge that would be "life-threatening" to anyone in its path.
Irma has already devastated parts of the Caribbean with at least 25 deaths. About 60 Indian nationals are being evacuated from the vacation island of St Martin in the Caribbean.
The eye of the Category 4 storm was 24 kilometers southeast of Key West.
The eye is a region of mostly calm weather at the center of strong tropical cyclones. The eye of a storm is a roughly circular area, typically 30?65 km in diameter.
Around 120,000 Indian-Americans reside across Florida while thousands of them live in the now-dangerous zones of Miami, Fort Lauderdale and Tampa.
Miami and Tampa appeared "ghost towns" as nervous residents, many of whom struggled to cope with abandoning their homes, moved to safer places following mandatory evacuation notices.
The National Weather Service (NWS) said Irma regained strength as a Category 4 storm - after being downgraded to Category 3 for more than 12 hours - as it moved to Florida.
The Indian embassy in the US has opened a round-the-clock helpline number and rushed senior diplomats to Atlanta to lead relief efforts for Indian-Americans stuck in the region.
The hotline number is 202-258-8819.
Embassy officials said India's Ambassador to the US Navtej Sarna was closely monitoring the situation.

Almost entire Florida was under hurricane warning.
US President Donald Trump reviewed preparedness with his cabinet colleagues at Camp David in Maryland. He asked federal and state agencies expedite assistance to affected areas.
"This is a storm of enormous destructive power, and I ask everyone in the storm's path to pay heed to all instructions from government officials," Trump said.
Florida Governor Rick Scott asked people to move out of the danger zones as soon as possible. "The state has never seen anything like this. The storm's surge can kill you."
The US Army has so far deployed more than 7,400 soldiers and US Army Corps of Engineers civilians on the US Virgin Islands, Puerto Rico, and the continental US.
The Pentagon said the army has over 140 aircraft, 650 trucks, 150 boats prepared, additional resources on standby.
AccuWeather, a forecast weather agency, warned Irma will unleash destructive winds, flooding, rain and inundating seas.
"Unfortunately, there is no way the US is going to avoid another catastrophic weather event," AccuWeather president Joel N Myers said.
"[It will be] the worst single hurricane to hit Florida since Hurricane Andrew in 1992," Myers said.
