Southern California Braces for Life-Threatening Rain and Flooding

Eight inches of heavy rain are possible in some areas of Southern California, according to the Weather Prediction Center’s unusual “high risk” forecast.

Difficult Weather Warning for Sunday: Up to an inch of rain expected every hour

Sunday was predicted to be “one of the most dramatic weather days in recent memory” with severe rainfall in some areas of Southwest California, possibly as much as an inch per hour. The storm could cause potentially fatal floods.

Warm tropical moisture will pour into California through an atmospheric river that gets stronger due to a strengthening coastal storm. Extreme weather warnings for potentially fatal flooding, hurricane-force winds, waterspouts, tornadoes, and significant snowfall are in effect for California on Sunday and Monday.

The National Weather Service in Los Angeles declared early on Sunday morning that “this major storm will bring a multitude of dangerous weather conditions to the area.”

Heavy Probability Forecast: Atypical Forecasts for Severe Conditions, Including Rain

The Weather Prediction Centre issued a rare “high risk” heavy rain forecast, meaning that eight or more inches of rain may fall in a single day, in an area that stretched from Los Angeles to Santa Barbara.

Forecasters rarely use this category, yet some of the deadliest and most disastrous floods of the past 10 years have occurred in areas that they considered to be at this degree of danger.

The Weather Prediction Centre reports that when a high threat is declared, at least one person dies or is injured almost half the time, and there is at least $1 million in damage roughly two out of every three times.

“Rain totals still look to be very impressive,” according to the National Weather Service on Saturday night. The totals will be at least three to six inches along the coast and six to twelve inches in the foothills and mountains.

On Saturday night, the rain had started to fall throughout California. It was only predicted to get stronger during the day and to rain almost nonstop for the next 48 hours as the storm system moved more slowly across Southern California.

Eric Schoening, an emergency response specialist with the National Weather Service, stated during a briefing on Saturday that the storm is also anticipated to bring widespread gusty winds and high mountain snowfall.

According to Mr. Schoening, “the most significant rainfall totals for this event are expected across the central and southern coastline, including the metro areas of Los Angeles and San Diego.”

He continued, “Lives and property will be in danger from this destructive flooding.” According to him, the circumstances are the result of an atmospheric river event.From Sunday to early Monday morning, forecasters warned that there is a significant probability of destructive and potentially fatal flooding in Los Angeles.

For residences near Sycamore Creek and along waterways connected to the Thomas, Cave, and Alisal burn sites, Santa Barbara County officials issued evacuation orders.

The California State Guard was ready for quick deployment and 21 swift water rescue teams were on standby, according to the governor’s office, which was prepared for the storm.

The Santa Barbara Unified School District declared on Friday that due to the storm, all schools and the district office will be closed on Monday. On Monday, Santa Barbara City College’s campuses will offer remote instruction, according to its website.

From Saturday evening through Sunday evening at 10 p.m. local time, the National Weather Service issued a high wind warning for portions of Southwest California.

Emergency Briefing: Atmospheric River Creating Destructive Flooding Risk

There was a forecast for winds of between 30 and 45 mph, with potentially devastating gusts as high as 65 mph. Forecasters said they might bring down power lines and trees, which would cause blackouts.

In the highlands and over the coastal waters, the winds may pick even more strength. There was a rare hurricane-force wind warning in effect for a few coastal areas on California’s central coast, where winds might gust to 74 mph or more.

It may seem like a long time ago to many Californians now, but those were the days when officials would stand on the brink of almost empty reservoirs and beg people to save water or watch their lawns die.

By the end of 2022, however, meteorologists were predicted that storms propelled by atmospheric rivers would bring substantial snowfall and rain, finally providing a break from the state’s protracted drought that dated back to 2020.

Readiness and Alerts: Shelter-ins, Closed Areas, and Telecom Guidance for Rainstorm

The opposite end of the pendulum swing between extreme weather was experienced by Californians in the ensuing months; these swings have widened as climate change has increased the intensity of rainy cycles and increased the temperature of dry times.

When a hurricane looked to be headed towards Southern California in August of last year, officials issued dire warnings because the winter and spring had been so brutal and deadly.
