As Hurricane Hilary continues its march toward Southern California, officials have issued an unprecedented tropical storm watch for the region.

The watch is in effect from the California-Mexico border to the Orange County-Los Angeles County line and for Catalina Island, something the National Hurricane Center said is a first for this area. A tropical storm watch means that tropical storm conditions are possible, generally within 48 hours, according to the hurricane center.

Hilary, currently a Category 4 hurricane, is expected to bring pounding rain and a “distinct risk” of flash floods from the Baja California Peninsula into southern Nevada over the next few days.

Fluctuations in the storm’s strength are expected throughout the day Friday, but a weakening should begin by the end of the day, forecasters said.
