Hurricane Hilary rapidly intensified into a Category 4 storm, gaining strength as it moved off Mexico's west coast.

Seasonally warm waters are fueling Hilary's development, taking it from a tropical storm to boasting winds of 145 miles per hour, as of Friday morning, according to the Los Angeles Times.

The storm could make land in Mexico over the weekend, subsequently bringing rains that could cause floods to California and the U.S. Southwest until Monday.

The National Weather Service in San Diego and a U.S. National Hurricane Center advisory highlights potential landfall across Baja California, anticipating its winds to have reduced to about 75 mph by then, according to the LA Times.

The Los Angeles Times emphasized that even as the system’s hurricane-strength winds weaken upon approach to the southwestern U.S., the region may still experience tropical storm-force winds, a phenomenon not seen since 1939.

Officials are urging communities to be vigilant and prepare for the storm’s impact, according to the Los Angeles Times.
