The hurricane centre predicts Irma will "move along or near the south-west coast" of Florida on Sunday.

As Hurricane Irma barreled toward Florida with 200 km/h winds Saturday hundreds of volunteers from Toronto's Caribbean communities gathered aid supplies to send to a string of Caribbean nations pummeled in its path earlier this week.

"We had Harvey, which was an unusual type of storm with masses and masses of flooding".

Tonight, Irma was still centered about 110 miles southeast of Key West. "We have plenty of water, plenty of food, plenty of hooch", he said.

Calling the situation an "obvious state of emergency", Rick Scott said that Florida has been very aggressive in its preparation for the storm, but he said locals will have to deal with its impact, including downed power lines and trees and blocked roads due to flooding.

The death toll from Hurricane Irma has risen to 22 as the storm continues its destructive path through the Caribbean.

Wayne Ploghoft hunkered down Sunday on the third floor of a building on Marco Island - where life-threatening storm surges are imminent.

Marlin said many countries and people have offered help to St. Maarten, but authorities were waiting on the weather conditions to see how it could be coordinated. Mandatory evacuation orders are underway in the Florida Keys and the Gulf Coast.

The US government said it was sending aircraft to evacuate citizens from one of the hardest hit islands, St Martin.

Hurricane Irma bore down on southern Florida on Sunday with 130 mile-per-hour (210 kph) winds, flooding Miami streets and knocking out power to more than 1.6 million homes and businesses.

At 11 p.m. Saturday, Irma was a category 3 hurricane and moving along the north coast of Cuba at about 6 miles per hour. In the Tampa Bay area, Scott said the storm surge could be between 5 feet and 8 feet. Hurricane warnings were still in effect Saturday for parts of central Cuba.

The storm's track along Florida's west coast "is nearly, if not, a worst-case scenario for Tampa Bay", said Rob Miller, a meteorologist at AccuWeather Inc.in State College, Pennsylvania.

Officials in other states also were preparing Saturday for Irma.

FEMA warned Alabama and North Carolina also to be on watch.

Florida Power & Light, the state's largest electric utility, said there were almost 1 million customers without power in Miami-Dade County alone.

"We try to get rid of most of the debris, seeing as we're going to be facing Jose in a few hours", Brooks said.

Editor's note: This is a developing story that is being constantly updated as the storm progresses.

Antigua and Barbuda were spared from the worst of Jose, as it skirted north of the island on Saturday and was downgraded to a tropical storm warning.

Approximately 44,457 SC residents are affected by the evacuations that went into effect Saturday morning on barrier islands in Beaufort, Colleton and Jasper counties, with the vast majority on Hilton Head Island.
