The latest advisory from the National Hurricane Center pegs the storm as a Category 5 hurricane with 180 mph top sustained winds. Irma is now one of only five storms in the history of hurricane measurements with a peak wind speed of 160 knots or higher (184 mph), according to the readings by US Air Force aircraft. The other four are Wilma from 2005, Gilbert from 1988, Allen from 1980 and the Labor Day Hurricane of 1935.Unfortunately, there’s nothing in the forecast that suggests Irma may weaken or turn toward the Atlantic away from land. In fact, the atmosphere in the storm’s projected track is conducive to further strengthening.Directly in the storm’s crosshairs are the Northern Leeward Islands and Puerto Rico. Both areas have been issued hurricane warnings, indicating that hurricane-force winds are expected within 36 hours. These areas (Antigua and Barbuda, Anguilla, Montserrat, St. Kitts and Nevis, St. Martin, Saba, St. Eustatius, St. Maarten and St. Barts, Puerto Rico, and the US and British Virgin islands) are facing catastrophic damage from winds and storm surge over the next two days. Travelers in these areas should take immediate action to evacuate or find shelter on high ground.Into Thursday and Friday, the storm is forecast to rocket north of the Dominican Republic and Haiti and into the Bahamas before slowing down as it approaches Cuba and Florida. Most of this time, the storm is expected to remain a massive and intense Category 5 hurricane. Small variations in the track can send Irma directly into any of the areas in the warning cone, so travelers should avoid these areas through the end of the week.The strength of this storm simply can’t be underestimated. Carlos Anselmi, a National Weather Service meteorologist in San Juan, told The Associated Press: “Puerto Rico has not seen a hurricane of this magnitude in almost 100 years.“In Florida, Governor Rick Scott has already declared a state of emergency even though the storm is still almost five days away. While the current forecast track takes the center of the giant storm south of Miami and into the Keys, forecasts this far out can’t be relied on to be exact. Travelers and residents up and down the Florida coast should closely monitor this storm and be prepared to evacuate or cancel plans to visit.For now, airlines are issuing weather travel waivers primarily for the Caribbean islands. However, travelers to parts not covered by the waivers should keep a close eye out for updates to those waivers. If you’re still able to cancel flights or hotels for free, you should strongly consider doing so.Sign up for our daily newsletterEmail addressSign upI would like to subscribe to The Points Guy newsletters and special email promotions.

But some top cards have flight delay/cancellation insurance that can reimburse you for weather issues, including the Citi Prestige ($500 per passenger for 3+ hour delay), the Chase Sapphire Reserve ($500 per ticket for 6+ hour or overnight delay) and Chase Sapphire Preferred ($500 per ticket for 12+ hour or overnight delay). My Citi Prestige personally came in handy a few weeks ago when I got stuck in Japan due to a typhoon-related flight cancellation.As of this writing, here are the available travel waivers for this storm:American AirlinesTravel dates: September 5-8Airports affected: Anguilla Wallblake, Anguilla (AXA); Antigua, Antigua (ANU); Beef Island, British Virgin Islands (EIS); San Juan, Puerto Rico (SJU); St. Croix Island, U.S. Virgin Islands (STX); St. Kitts, Saint Kitts and Nevis (SKB); St. Maarten, Saint Maarten (SXM); St. Thomas Island, U.S. Virgin Islands (STT); Cap-Haitien, Haiti (CAP); Port-au-Prince, Haiti (PAP); Puerto Plata, Dominican Republic (POP); Providenciales, Turks and Caicos (PLS); Punta Cana, Dominican Republic (PUJ); Santo Domingo, Dominican Republic (SDQ); Santiago, Dominican Republic (STI)Must have bought your ticket by September 3Rebook travel anytime between September 5-12You can’t change your origin or destination city.
