MEXICO CITY, Mexico (AP) -- Tropical Storm Henriette formed off Mexico's Pacific coast Friday and was forecast to move parallel to the mainland, the National Hurricane Center in Miami, Florida, said.
A tropical storm warning was issued for Mexico's southern coast from Lagunas de Chacahua to Punta San Telmo.
At 8 a.m. ET, the center of Henriette was 85 miles (137 kilometers) south of Acapulco, with maximum sustained winds of 40 mph (64 kph).
It was moving west-northwest at near 10 mph (16 kph) and is expected to continue on the path for the next 24 hours, moving near and parallel to Mexico's Pacific coast, forecasters said.
Henriette was expected to bring 4 to 8 inches of rain along the southern coast, and flooding and landslides were possible.
