After weakening to a tropical storm on Tuesday afternoon, the National Hurricane Center says Pamela now has maximum sustained winds of 75 mph, making it a Category 1 hurricane.
As of 3 a.m. MT Wednesday morning, U.S. National Hurricane Center says the storm was centered about 80 miles west-southwest of Mazatlan and was moving northeast at about 14 mph.
The hurricane center warns of possible life-threatening storm surges, flash floods and dangerous winds around the impact area.
Weakened remnants of the storm may reach Texas by Thursday.
