MIAMI (AP) -- Hurricane Ida was weakening as it headed for the Gulf Coast but could still pack hurricane winds and storm surges when it hits the shore Monday night or early Tuesday.

The U.S. National Hurricane Center in Miami said that top sustained winds from the Category 1 hurricane had decreased to near 80 mph early Monday.

Hurricane warnings remain from Pascagoula, Miss., east to Indian Pass, Fla. Tropical storm warnings and hurricane watches are in effect across neighboring areas including New Orleans.

Early Monday, Ida was located about 235 miles south-southeast of the mouth of the Mississippi River and moving north-northwest near 16 mph.
