A tropical storm warning was issued and is still in effect as Tropical Storm Dolly moved over Mexico's Yucatan Peninsula.

Authorities in towns and cities from the Mexico-Belize border northward to the city of Campeche, on the opposite side of the Yucatan Peninsula, are on their toes as they expect the tropical storm to hit the area. The tourist resort of Cancun is also under alert.

According to expert meteorologists, the tropical Storm Dolly it’s on its way towards the Gulf of Mexico where it could become a hurricane on Tuesday, U.S. National Hurricane Center informed.

Meteorologists forecasted that Dolly will march across the southwestern Gulf and hit the South Texas coast near the Mexico border in about three days. Monitors showed that Dolly was moving northwest at nearly 15 miles per hour and is expected to turn to the west-northwest today. The storm’s maximum sustained winds were of about 50 mph with higher gusts. Forecasts show that Dolly will most likely gather additional strength when its center moves into the Mexican Gulf.

Dolly was about 150 miles (240 kilometers) east of Progreso, Mexico, at about 5 a.m. ET today (Monday). The tropical storm could turn into a hurricane according to the hurricane center.

The National Hurricane Center also issued advisories regarding the Tropical Storm Cristobal which is currently about 30 miles east of Cape Hatteras, North Carolina. However, it appears that Cristobal is turning away from land. Storm warnings issued for the North Carolina coast were lifted Sunday night. The Atlantic hurricane season began June 1 and ends in November.
