Tropical Storm Dorian is about to lash Puerto Rico with torrential rains, and then is expected to gain strength and become the first major hurricane to hit Florida’s east coast in 15 years.
Chances are increasing that the storm will approach Florida with winds of 115 miles per hour, making it a Category 3 hurricane, according to the U.S. National Hurricane Center. But first, it will sideswipe the eastern corners of Puerto Rico and the U.S. Virgin Islands within the next few hours.
Dorian’s winds are now 70 mph, just 4 mph below hurricane status, according to the center’s 11 a.m. update. While it won’t hit Puerto Rico with the same force as Hurricane Maria’s 155 mile-per-hour winds in 2017, it’s the first significant storm to threaten the island since then. And it’s getting more organized, the center reported.
“Dorian is forecast to become a hurricane later today, and continue strengthening during the next few days over the Atlantic waters,” according to the center. Hurricane warnings have now been issued for Puerto Rico, the U.S. Virgin Islands, the British Virgin Islands, Vieques and Culebra.
The last major hurricane to make landfall along the central coast of Florida carrying winds of 111 mph or more was Jeanne in 2004, said Phil Klotzbach, a hurricane researcher with Colorado State University. Dorian threatens to become the strongest storm to hit anywhere in Florida since Hurricane Michael last year.
“The central coast of Florida and even up to the Carolinas should be watching out for this,” said Adam Douty, a meteorologist with AccuWeather Inc. in State College, Pennsylvania. There is “high confidence” it will be a strong Category 1 or even Category 2 hurricane when it strikes early next week, he said.
Dorian was about 25 miles (40 kilometers) southeast of St. Croix as of 11 a.m. New York time, making the U.S. Virgin Islands and Puerto Rico, still suffering aftereffects from Maria two years ago, as the most immediate concerns.
While still a tropical storm, Dorian could drop 4 to 6 inches of rain on the islands, according to the hurricane center, and as much as 10 inches in some isolated places. That could spur significant flooding within Puerto Rico, where some homes and businesses are still covered with tarps following the devastation from Maria.
At the same time, the island’s aging and long-neglected power grid was all but destroyed when Maria hit, and remains suspect with parts of the U.S. territory regularly without power.
“Most of Puerto Rico will be spared,” according to Accuweather’s Douty. “There could be moderate impacts from power outages because their infrastructure is so fragile.”
Dorian is lopsided, with most of its power on its eastern side, which will be pointed away from Puerto Rico as it passes later Wednesday into early Thursday, Douty said.
President Donald Trump has approved an emergency declaration for Puerto Rico and ordered federal assistance for the territory to support local response. Meanwhile, residents of San Juan have been crowding into shopping centers to stock up on food and water, and boarding up windows to keep them from breaking.
We are tracking closely tropical storm Dorian as it heads, as usual, to Puerto Rico. FEMA and all others are ready, and will do a great job. When they do, let them know it, and give them a big Thank You – Not like last time. That includes from the incompetent Mayor of San Juan!

Puma Energy says it will shut both Bayamon and Guaynabo 2 oil product terminals in Puerto Rico as part of its storm protocol. Ports in St. Croix in the U.S. Virgin Islands and Puerto Rico are shutting, and Governor Wanda Vazquez has declared a state of emergency.
The storm shifted course overnight, and is now set to brush across Puerto Rico’s east coast rather than its center, according to the hurricane center. That means it’s heading northwest over open water instead of bumping into the mountains of Hispaniola that could have sapped it of power. The new path shows it menacing Orlando by early Monday.
Ports in St. Croix in the U.S. Virgin Islands and Puerto Rico were shut on Wednesday as Dorian approaches, the U.S. Coast Guard said in a statement. A hurricane watch was issued for Vieques, Culebra and the Virgin Islands.
Meanwhile, tropical depression Erin is racing up the East Coast with winds of 35 mph, and is now located 190 miles southeast of Cape Hatteras, the hurricane center reported.
Erin will transition into a post-tropical system when it slams the eastern end of Nova Scotia late Thursday or early Friday. A cold front moving across the eastern U.S. will tap into its moisture and bring heavy rain to eastern New England, including Boston, late Wednesday, Accuweather’s Douty said.
Flash flood watches have been posted across parts of Rhode Island, Massachusetts, New Hampshire and Maine, a coastline crowded with tourists for the upcoming Labor Day weekend holiday.
