MIAMI -- Tropical Storm Karen has formed in the Gulf of Mexico, and a hurricane watch is in effect along the Gulf Coast from Louisiana to Florida.

The U.S. National Hurricane Center in Miami says the late-season storm formed Wednesday morning. At 9 a.m., it was about 40 miles northwest of Cabo Catoche, Mexico and about 500 miles south of the mouth of the Mississippi River. Its maximum sustained winds were 60 mph and it was moving north-northwest at 13 mph.

The hurricane watch is in effect from Grand Isle, La., to Indian Pass, Fla. A tropical storm watch also was in effect for parts of the Louisiana coast west of Grand Isle, including the metro New Orleans area and Lake Pontchartrain.

Meanwhile, out in the Atlantic, Tropical Depression Jerry is expected to weaken.

The depression’s maximum sustained winds early Thursday were near 35 mph. The Hurricane Center says the depression is expected to become a remnant low on Friday.

Jerry is centered about 985 miles west-southwest of the Azores and is moving northeast near 9 mph.

The depression isn’t currently threatening any land.
