Several flights into and out of San Francisco were canceled on Thursday due to the impacts of Hurricane Matthew in Florida.
So far there have been 14 cancellations, including nine arrivals and five departures, San Francisco International Airport Duty Manager Bob Rotiski said.
The flights were scheduled to fly into or out of Ft. Lauderdale-Hollywood International Airport, Miami International Airport and Orlando International Airport. And the affected airlines are JetBlue, United, American and Virgin America, he said.
Hurricane Matthew is described by the National Weather Service as a Category 4 storm with sustained winds of nearly 140 mph. It is moving toward the east coast of Florida, according to the National Weather Service.
Ft. Lauderdale-Hollywood International Airport was closed to all flights early Thursday morning due to the storm's expected path along the coast.
Orlando International Airport halted all flights Thursday evening, and Miami International Airport website also alerted travelers to cancellations.
Airlines across the country have cancelled more than 3,000 flights and American Airlines, which has a hub in Miami, was hit hard.
Both the Oakland International and the Mineta San Jose International airports are not reporting delays or cancellations, as they don't offer direct flights to the storm-lashed region of Florida, but passengers are being advised to keep a close eye on their flights.
"There could be residual effects throughout the airlines' networks," Mineta San Jose International Airport spokeswoman Rosemary Barnes said. "Anyone traveling should check with the airlines directly."
Meanwhile, PG&E plans to send 100 workers to Florida. A mutual aid agreement says crews from the Bay Area will help restore power in the hurricane-lashed areas.
