Forecasters at the National Oceanic and Atmospheric Administration's Climate Prediction Center said the Atlantic may have an above-average hurricane season this year, with a 70-percent likelihood of 11 to 17 named storms, of which five to nine could become hurricanes, including two to four major hurricanes.

A tropical storm warning has been issued for a section of Louisiana's coast as a weather system approaches from the Gulf of Mexico.

There's a good chance a tropical cyclone could develop in the Gulf of Mexico this week, but Harrison County Emergency Manager Rupert Lacy said there's still a lot of uncertainty with the system.

The Yucatan system is expected to move northwest over the Yucatan Peninsula today and into the southern or central Gulf of Mexico tomorrow and Tuesday.

The system is expected to continue moving toward the west or west-northwest at 15 to 20 miles per hour over the tropical Atlantic during the next several days, according to the service.

Monday will see around a 40 percent chance of rain with the most of that happening rain south of Lake Pontchartrain.

With this storm, a broad trough of low pressure is creating a large stretch of cloudiness and showers over the northwestern Caribbean Sea and adjacent land areas.

Regardless of development, heavy rains are expected to continue over portions of Central America, the Yucatan Peninsula, the Cayman Islands, and western Cuba during the next day or two. It is important to note at this time that the models DO NOT have a great handle on the system yet as it does not have a well defined center of circulation.

The system's maximum sustained winds early Tuesday are near 40 miles per hour.

Tropical-storm-force winds extend outward up to 205 miles, mainly to the east of the center.

A tropical storm watch is also in effect on the upper Texas coast from west of High Island to San Luis Pass.
