Hundreds of tourists were forced to flee resorts as a tropical storm swept through the Yucatan Peninsula, northern Guatemala and Belize on Saturday.

Tropical Storm Alex weakened to a depression Sunday hours after making landfall in Cancun.

But it is expected to regain strength this week as it moves out over warmer waters in the Gulf of Mexico.

Torrential downpours accompanied winds reported to be up to 95 km/hr when the storm made landfall in Belize on Saturday night but had decreased to 55 km/hr by Sunday morning.

Belize officials opened storm shelters in the island resort of San Pedro, as 1,400 people fled for the mainland.

Tourists along Mexico’s Caribbean coast were advised to stay out of rough surf churned up by the storm. There were no immediate reports of damage to destinations such as Cancun, Cozumel, Playa del Carmen or Tulum.

Alex is the first named storm of the Atlantic hurricane season with concerns being raised over the impact it could have on efforts to contain the millions of gallons of crude oil spewing into the Gulf of Mexico.
