Storm history of Hurricane Wilma
The depression tracked slowly westward, a motion due to weak steering currents caused by a high pressure system to its north across the Gulf of Mexico. Initially, the center of circulation was broad without a defined inner core; forecaster Lixion Avila remarked, "The area of minimum pressure could [have been] anywhere within 60 miles (95 km) of its [initial advisory position]." Originally, the tropical depression was forecast to drift west-southwestward before turning to the north; within 120 hours of the forecast's issuance, the system was predicted to be about 80 miles (130 km) south of the Isle of Youth as a 105 mph (170 km/h) hurricane. However, the National Hurricane Center noted in the first advisory on the depression that there were "all indications that there could a dangerous hurricane in the northwestern Caribbean Sea in 3 to 5 days." This was due to the depression being in an environment very ideal for development, specifically low amounts of wind shear and very warm water temperatures.
