Hurricane Dorian is forecast to strengthen and become a highly dangerous Category 4 hurricane on Sunday, threatening the Atlantic coast of central and south Florida where authorities canceled some commercial flights on Thursday and planned precautions at rocket launch sites along the Space Coast.
Spurred on by warm late-summer waters, Dorian is predicted to pack winds reaching 130 mph (209 kph) in 72 hours, the Miami-based National Hurricane Center said.
That would make it a Category 4 storm, the second-strongest on the Saffir-Simpson scale for measuring hurricane intensity.
The center describes Category 4 storms as capable of causing catastrophic damage including severe damage to well-built homes. It said in such storms, “Most trees will be snapped or uprooted and power poles downed.”
Dorian is likely to make landfall on Florida’s eastern coast on Monday before lingering over central Florida on Tuesday, the hurricane center said. The storm could affect big population centers as well as major Florida tourist destinations.
Currently a Category 1 hurricane, Dorian was headed toward the Bahamas on Thursday after sideswiping Caribbean islands without doing major damage. Dorian is expected to strengthen and slam the Bahamas and the southeastern United States with rain, strong winds and life-threatening surf over the next few days.
Dorian was packing maximum sustained winds of 85 miles per hour (137 km per hour) on Thursday morning some 220 miles (355 km) north-northwest of San Juan, and about 370 miles (600 km) east of the Bahamas, the hurricane center said.
U.S. President Donald Trump urged Floridians to heed official warnings. Governor Ron DeSantis declared a state of emergency on Wednesday and asked residents along the east coast to stock up with at least seven days worth of supplies such as food and water.
“Hurricane Dorian looks like it will be hitting Florida late Sunday night,” Trump wrote on Twitter. “Be prepared and please follow State and Federal instructions, it will be a very big Hurricane, perhaps one of the biggest!”
Jim McKnight, city manager of Cocoa Beach on central Florida’s Atlantic coast, made sure construction sites were secured with possible dangers like scaffolding taken down to prevent flying objects.
“We’re worried. This is not looking good for us. We woke up a lot more scared than we went to bed last night, and the news is not getting any better,” said Angela Johnson, 39, bar manager at Coconuts On The Beach, a Cocoa Beach bar and restaurant on the town’s surfing beach.
The biggest hurricane to have come ashore in the area in recent history was Jeanne in 2004, which made land around Port St. Lucie as a Category 3 storm.
“Dorian is expected to become a major hurricane on Friday, and remain an extremely dangerous hurricane through the weekend,” the hurricane center said, warning of an increasing likelihood of life-threatening storm surge along portions of Florida’s east coast late in the weekend.
Two flights from the Orlando International Airport to Puerto Rico were canceled, and travelers were urged to monitor local storm forecasts and check with airlines for any more flight cancellations.
The Cape Canaveral space center said it would close Saturday afternoon with a skeleton team of roughly 100 staff staying behind in the launch control room to monitor the storm and the site’s aerospace assets.
NASA’s Kennedy Space Center said it would move a 400-foot (122-meter) tall, $650-million mobile launcher structure used to assemble the agency’s rocket for future moon missions from a launchpad and into a building to take shelter during Dorian’s likely impact.
Nearby towns were checking storm drains and back-up generators for waste-water plants as well as setting up round-the-clock shifts for emergency personnel.
The University of Central Florida, one of the largest U.S. universities by student population, said its main campus in Orlando will close on Friday afternoon.
The storm was forecast to approach on Saturday the northwest of the Bahamas, a popular tourist spot, the hurricane center said. Officials of the nation’s northernmost island Grand Bahamas urged residents on Wednesday evening to secure houses and businesses immediately.
