A hurricane watch has been issued for coastal Louisiana and Mississippi as Hurricane Ida begins making its way through the Gulf of Mexico toward the U.S.

Ida could reach the northern Gulf Coast by Tuesday.

Forecasters at the National Hurricane Center in Miami said Sunday morning that the watch does not include New Orleans and stretches from Grand Isla, La., to the Mississippi-Alabama state line. The watch means hurricane conditions are possible within 36 hours.

A hurricane warning remained in effect for parts of the Yucatan Peninsula meaning hurricane conditions are expected within 24 hours.

Ida's winds remained at 90 mph (150 kph), making it a Category 1 storm. It was moving toward the northwest at 10 mph (17 kph) and was centered about 75 miles (120 km) northeast of Cozumel, Mexico.
