With forecasts solidifying for the timing and location of landfall, airlines have started cancelling flights, expanding weather waivers and some airlines are waiving fees to help those evacuating the area.As of the 5:00pm National Hurricane Center advisory, Hurricane Florence completed its eyewall replacement cycle and regained 140mph top sustained winds. As the storm will remain in a very favorable environment over the next 24 hours, Florence is expected to strengthen further. Forecasts still call for Florence to retain “major hurricane” status when it makes landfall on the North Carolina coast on Friday afternoon.While the hurricane is currently steaming toward the Southeast Coast at a fast 17mph clip, the NHC notes that the “steering currents will collapse” as the dangerous hurricane approaches the coast. This is going to result in the hurricane stalling out over the Carolinas shortly after landfall.The NHC predicts that this will cause “life-threatening, catastrophic flash flooding and significant river flooding” through the Carolinas and into Virginia. With each update, the predicted rainfall totals have gotten more concerning — especially for the coast that’s expected to take a beating from the strong winds and high surf. While the map below tops out at 20 inches of rain, NHC forecasts note that the storm may dump “isolated maximum amounts of 35 inches” of rain in parts of the warning area.Researchers from the University of Michigan are predicting that the hurricane will leave approximately 3.3 million residents without power.Image courtesy of Guikema Research Group from the University of Michigan.Evacuation of Air and Sea FleetsAhead of the storm, Boeing shut down production of Dreamliners at its Charleston plant and has flown all airworthy Dreamliners from Charleston to its other Dreamliner plant in Everett, Washington. The Navy isn’t taking any chances with its fleet either, sending all ships out to sea from its Hampton Roads navy base.Flight CancellationsSign up for our daily newsletterEmail addressSign upI would like to subscribe to The Points Guy newsletters and special email promotions.
