Hurricane Irma, barreling toward the Caribbean and the southern United States, was upgraded to a powerful Category 4 storm on Monday as islands in its path braced for a possible onslaught.
Hurricane advisories were issued for territories that dot the West Indies, including parts of the Leeward Islands, the British and US Virgin Islands and Puerto Rico, in preparation for the intensifying storm that could pummel the area with life-threatening wind, storm surges and torrential rain by Tuesday evening, according to the US National Hurricane Center (NHC).
Ahed Daas, owner of the Food Center in St. Thomas, U.S. Virgin Islands, said traffic at his store on Monday was about 50 per cent higher than normal as people stocked up on water, canned products and batteries. Since it is the off-season for tourists, almost all the customers are local and there were few liquor sales.
People began to shop as early as last week as Irma neared and continued through the weekend.
"It’s kind of dwindling down now, everybody’s pretty much stocked up," Daas said. "You make sure you have fuel in your generator and hope it’s not that bad when it does arrive."
A Category 4 hurricane on the five-step Saffir-Simpson scale means sustained winds of 209-251 kmph with "catastrophic" outcomes, including uprooted trees and downed power lines, water and electricity outages, and significant property damage causing uninhabitable conditions, according to the Miami-based hurricane center.
Irma, now packing 220 kmph winds, also threatens the US East Coast and Florida, which on Monday evening declared a state of emergency. The hurricane center expects Irma to reach southern Florida on Saturday.
The NHC cautioned that it was too early to forecast the storm's exact path or what effects it might have on the continental United States, but warned of likely effects to hit some areas by later this week.
"There is an increasing chance of seeing some impacts from Irma in the Florida Peninsula and the Florida Keys later this week and this weekend. In addition, rough surf and dangerous marine conditions will begin to affect the southeastern US coast by later this week," the center said.
Irma will be the second powerful hurricane to thrash the United States and its territories in as many weeks.
Residents of Texas and Louisiana are still reeling from the catastrophic effects of the deadly Hurricane Harvey, which struck Texas as a Category 4 hurricane on Aug. 25 and dumped several feet of rain, destroying thousands of homes and businesses.
Irma is forecast to strengthen over the next 48 hours and could "directly affect Hispaniola, the Turks and Caicos, the Bahamas, and Cuba as a dangerous major hurricane later this week," the NHC said.
In preparation for the storm, the government of economically struggling Puerto Rico on Monday declared a state of emergency and activated the National Guard.
"Despite the economic challenges Puerto Rico is facing, the approved budget has $15 million for the emergency fund," Governor Ricardo Rosselló said in a statement.
The US island territory, home to about 3.4 million people, has 456 emergency shelters prepared to house up to 62,100 people.
To help residents prepare for the storm, Puerto Rico activated a price freeze on basic necessities, including food and water, medicines, power generators, and batteries.
Telemundo TV station WIPR in Puerto Rico showed long lines of shoppers stocking up on bottled water, flashlights, batteries, generators, food and other items.
The executive director of the state power authority, Ricardo Ramos, told the station that the power grid was so vulnerable from lack of investment that parts of the US territory could be without power for three to four months.
"We're preparing for the worst-case scenario," he said.
