Waves from Hurricane Wilma have started to pound Mexico’s beach resorts as the category four storm heads across the Caribbean to Florida. Wilma may yet strengthen again to category five, the highest.Mexico’s president Vicente Fox has already told his country to expect the worst. “At this moment and in these next few hours and these few days, what’s most important is to protect life, to protect the family, to protect our children,” he said. In Florida people are evacuating their homes and gathering in shelters, a drill that is becoming all too familiar. Experts say the Atlantic has begun a period of heightened storm activity that could last 20 more years. Described by forecasters as extremely dangerous, Wilma has killed at least 13 people in the Caribbean and is set to hit Florida on Sunday. With images of hurricane Rita’s destruction in their minds, the fear is rising in Florida. But the petrol queues are commonplace for people who have weathered three of the worst storms on record this hurricane season.
