Tropical Storm Paul was closing in on Mexico's Baja California peninsula on Wednesday. At least 1,000 residents in low-lying shantytowns were evacuated.
The storm, previously a hurricane, was weakening but still had winds of 45 mph. It was expected to make landfall near the resort of Mazatlan on Mexico's mainland Pacific coast.
Residents could expect 10 inches of rain, and there was a risk of flash flooding and mudslides, according to the National Hurricane Center.
Already, one death has been blamed on Tropical Storm Paul. One person is missing.
Mexico's Pacific coast was hit by two hurricanes last month. Hurricane John hit Baja California, killing five people and destroying 160 homes. Hurricane Lane hit near Mazatlan but did not cause severe damage.
