Two hurricanes in the Pacific Ocean near Mexico, named Polo and Odalys, are creating high surf conditions along Southern California’s coastline. This overlaps with an unusual high tide, posing risks for beachgoers and potential coastal flooding.
Polo is a Category 4 hurricane with winds reaching 140 mph. It’s predicted to make landfall in Baja California Sur on Monday, bringing significant rainfall and flooding. Odalys, with 90 mph winds, is located about 900 miles west of the southern tip of Baja California and is expected to move away from land.
According to Marty Ralph, director of the Center for Western Weather & Water Extremes at UC San Diego, the persistence of such a strong hurricane so far north is unusual. He attributes this to unusually warm ocean temperatures, enhanced by a marine heat wave and a strong El Niño event.
“To have a storm of this intensity persist as a strong hurricane all the way into Baja is unusual,” Ralph said, referring to the warming ocean waters off Mexico.
Hurricane Nolo is also affecting Hawaii with strong winds and heavy rains.
In Los Angeles and Ventura counties, forecasts indicate surf between four and seven feet on Monday and Tuesday, accompanied by strong rip currents and possible coastal flooding. Lisa Phillips from the National Weather Service warned of the increased ocean water levels coinciding with high tides.
“Ocean water is going to creep up higher than normal,” Phillips noted, highlighting the potential for coastal flooding and beach erosion.
A coastal flood advisory has been issued for L.A. and Ventura counties starting Monday extending through Wednesday for Orange and San Diego counties. Beachgoers are advised to check with lifeguards and avoid rock jetties for safety.
Previously, Hurricane Marie caused damage to beachfront properties and eroded beaches in Southern California. In response, Long Beach crews are reinforcing areas with sandbags and bolstering seawalls.
As Polo moves over Mexico, some areas of Southern California may experience unusual clouds and light showers. Arizona and New Mexico are expected to receive significant rainfall, possibly aiding the Colorado River’s reservoirs.
