TORONTO — WestJet is now offering flexible rebooking options for five Florida gateways plus Nassau as Tropical Storm Dorian hones in on Puerto Rico at close to hurricane strength.

WestJet, which earlier had put Samana, Puerto Plata and Punta Cana on its advisory list, has now added Fort Lauderdale, Orlando, Miami, Fort Myers and Tampa, for travel on Sept. 1. Also added to the list is Nassau, for travel Aug. 30 – Sept. 1.

Air Canada is waiving change fees for Puerto Plata and Punta Cana, for departures today.

Tropical Storm Dorian is currently approaching Puerto Rico at near-hurricane force, and forecasters say it could strengthen further as it approaches the U.S. mainland. The island is still getting back on its feet after Hurricane Maria in 2017. Dorian could hit Florida by the weekend.

According to the CTO, Saint Lucia has given the all-clear post-Dorian. The BVI is under curfew from 2 p.m. today until 6 a.m. tomorrow morning (Aug. 29), or until an all-clear is issued, to ride out the storm.

Barbados is also clear of Dorian. In her statement Prime Minister Mia Amor Mottley thanked Barbadians for their compliance and commitment. There are still three months to go in the hurricane season, she added. “The system allowed us to mobilize and focus on some areas…. The work done on Sunday made a significant difference in our state of readiness,” said Mottley.
