Don’t let the sunny, crisp fall air fool you, Orange County officials warned Wednesday. El Niño is coming and residents should be prepared.
“The severity of the storm can come really quickly and can change quickly,” said Orange County Supervisor Andrew Do.
Federal meteorologists with the National Oceanic and Atmospheric Administration said last week the anticipated El Niño pattern is still on track to be one of the strongest in recorded history.
Water temperatures in the Pacific were above average, warmer than temperatures in November 1997, the report stated, while winds have also weakened allowing more warm water to reach the Southern California coast for a wet and stormy winter.
"The last time our county got pounded was in 1997," said O.C. Board of Supervisors Chairman Todd Spitzer. On December 7 of that year, seven inches of rain fell in Orange County in one day. "It inundated all of our cities and all their capacity to deal with flooding," he said.
In South Orange County, the concern is for the burned out canyon hillsides.
“We are very afraid of what a significant amount of rain will do in terms of mud debris,” said O.C. Board of Supervisors Chairman Todd Spitzer.
If Orange County is expected to receive six inches of rain in a 24-hour period, officials will activate the emergency operations center. Mass evacuations and declarations of emergency from two or more cities in Orange County will also trigger activation.
“If we are seeing our burn area and looking at a forecast that will put us into a possible debris flow in those burn areas, we will activate this facility,” said Donna Boston, director of emergency management with the O.C. Sheriff’s Department.
Emergency responders are asking residents to clear out gutters, surround homes with sandbags to protect vulnerable areas from flooding, and inspect trees that have been weakened by the drought.
Orange County Public Works Director Shane Silsby said some crews have shifted from regular operations and maintenance to emergency preparedness procedures.
“Instead of that person going out and doing some channel clearing for nuisance trash,” he said. “They are assigned to do sediment removal in a facility that would be more susceptible to flooding.”
Do said county workers have been walking the Santa Ana River bed where hundreds of homeless people live to warn them.
Last week, county supervisors approved $500,000 to negotiate contracts with non-profit homeless shelters for emergency beds in case of bad weather.
Approximately 440 homeless people are living in 30 different regions of the Santa Ana River bed, according to a county spokesperson.
“We believe on a temporary basis we do have the ability to meet the need of all those people,” said Do.
