Looters have ransacked food stores and other businesses in the Mexican resort town of Cancun in the wake of Hurricane Wilma, which battered Mexico's Yucatan Peninsula for more than two days.
Witnesses have reported widespread property damage and flooding, with thousands staying in emergency shelters.
People waded through the streets of Cancun Sunday, looking for food and clean water. Military officials and police were brought in to stand guard in Cancun's main shopping area where at least 50 people were arrested for looting.
Food was reported to be running out on the resort island of Cozumel where damaged docks made it difficult for help to arrive. Four bodies were found floating in flood waters there. At least three other deaths in Mexico are attributed to Wilma.
Tropical storm Alpha caused flooding and forced thousands from their homes in Haiti and the Dominican Republic Sunday. Nearing the Bahamas, Alpha has been downgraded to a tropical depression.
