How to track Hurricane Irma’s progress in real time as it hits land


Harvey relief is barely underway, but Americans are already bracing for the impact of another potentially deadly storm. Hurricane Irma, which has been gaining strength in the Atlantic Ocean for the last week, was upgraded by the National Weather Service to a category 5 storm early Tuesday morning. With winds of 180 miles per hour, Irma is the strongest hurricane ever recorded in the Atlantic.

As of Tuesday morning, the storm had reached is a few hundred miles east of the Leeward Islands, near Puerto Rico, moving west at 15 miles per hour. Forecasters expect Irma to hit Puerto Rico on Wednesday, then move through the northern half of the Dominican Republic, and then on towards Cuba. From there, the path is less clear. Irma could veer north to the southern coast of Florida or it could turn to the south of Cuba, avoiding the US entirely. It’s still too soon to forecast Irma’s exact path, but there is a significant chance it will strike at least a part of south Florida (which includes the Florida Keys) this weekend.

Florida governor Rick Scott declared a state of emergency on Monday to trigger the swift activation of resources for storm preparation across the state. The National Weather Service issued a hurricane warning Tuesday morning for parts of the Caribbean, including the US and British Virgin Islands and Puerto Rico, urging any storm preparations “be rushed to completion.”

The National Weather Service called the storm “extremely dangerous” and estimates Irma could raise water levels by as much as 11 feet above normal tide levels on the coasts of the Leeward Islands and the storm itself could dump as much as 12 inches of rain on parts of the Caribbean, which could lead to flash flooding and mudslides.

“Some fluctuations in intensity are likely during the next day or two,” said the National Weather Service, “But Irma is forecast to remain a powerful category 4 or 5 hurricane during the next couple of days.”
