Tropical Storm Hilary swirled northward Sunday just off the coast of Mexico’s Baja California peninsula, no longer a hurricane but still carrying so much rain that forecasters said “catastrophic and life-threatening” flooding is likely across a broad region of the southwestern U.S.

As of 8 a.m. Pacific time, Hilary was located about 220 miles (350 kilometers) south-southeast of San Diego, the National Hurricane Center reported. Hilary had maximum sustained winds of 70 mph (110 kph) and was moving northwest at 25 mph (41 kph).

The Mexican cities of Ensenada and Tijuana remained directly in the tropical storm’s path, and meteorologists warned that despite weakening, the storm remained treacherous.

One person drowned Saturday in the Mexican town of Santa Rosalia, on the peninsula’s eastern coast, when a vehicle was swept away in an overflowing stream. Rescue workers managed to save four other people, said Edith Aguilar Villavicencio, the mayor of Mulege township.

It was not immediately clear whether officials considered the fatality related to the hurricane, but video posted by local officials showed torrents of water coursing through the town’s streets.

Forecasters said the storm was still expected to enter the history books as the first tropical storm to hit Southern California in 84 years, bringing flash floods, mudslides, isolated tornadoes, high winds and power outages. Authorities issued an evacuation advisory for Santa Catalina Island, urging residents and beachgoers to leave the tourist destination 23 miles (37 kilometers) off the coast.

Elizabeth Adams, a meteorologist at the National Weather Service San Diego office, said rain could fall up to 3 inches (7.62 centimeters) an hour across Southern California’s mountains and deserts, from late Sunday morning into the afternoon. The intense rainfall during those hours could cause widespread and life-threatening flash floods.
