The effects of Hurricane Wilma in Mexico severely affected the tourism industry of the Yucatán Peninsula in mid October 2005. Hurricane Wilma developed on October 15 in the Caribbean. Four days later, it intensified into the strongest Atlantic hurricane on record as determined by barometric pressure. Wilma weakened as it moved slowly northwestward, eventually making landfall late on October 21 on the island of Cozumel. At the time, it was a Category 4 hurricane on the Saffir–Simpson scale. Early the next day, the hurricane made another landfall on the Mexican mainland near Puerto Morelos. Wilma exited the Yucatán Peninsula into the Gulf of Mexico on October 23, and a day later it struck Florida.
