Santa Cruz County Braces for Atmospheric River: Essential Preparedness Guide for Flooding and Storm Impacts
“Santa Cruz Mountains could receive up to 7.5 inches of rain during the incoming atmospheric river event.”
As we face another atmospheric river event in Santa Cruz County, our community must come together to prepare for the potential impacts of this significant weather system. After a brief respite of sunny skies, we’re once again gearing up for heavy rainfall, high winds, and the possibility of flash flooding. In this comprehensive guide, we’ll explore the forecast, potential risks, and essential preparedness measures to help our residents weather this storm safely.
Understanding the Atmospheric River
An atmospheric river is a long, narrow band of moisture in the atmosphere that can transport significant amounts of water vapor from tropical regions to higher latitudes. These weather phenomena are often responsible for intense rainfall events along the West Coast, particularly in California.
The National Weather Service has issued flash flood warnings for our region, emphasizing the potential for dangerous conditions. As we brace for this incoming storm, it’s crucial to stay informed and take necessary precautions.
Forecast and Expected Impacts
Meteorologists predict that the new storm system will arrive late Tuesday and significantly impact our region from Wednesday to Thursday. Here’s what we can expect:
- Rainfall: The Santa Cruz Mountains could see up to 7.5 inches of rain, while other areas may receive between 3 to 5 inches.
- Wind: Wind gusts are expected to reach 40 mph in mountainous areas and 30 mph in lower elevations.
- Flooding: The San Lorenzo River is already nearing action levels, and we anticipate quick responses due to the previous week’s rain.
- Landslides: Saturated soils increase the risk of landslides, particularly in mountainous and coastal areas.
- Coastal Impacts: Significant swells at local beaches may hinder river drainage into the ocean, potentially exacerbating flooding issues.

Flood-Prone Areas of Concern
Residents in flood-prone areas should be particularly vigilant. Areas of concern include:
- Felton Grove
- Paradise Park
- Low-lying areas near the San Lorenzo River
- Coastal regions susceptible to storm surge
If you live in these areas, it’s essential to have an evacuation plan ready and stay tuned to local alerts for potential evacuation orders.
Wind Hazards and Tree Safety
“Wind gusts in mountainous areas of Santa Cruz County are expected to reach speeds of up to 40 mph.”
The combination of saturated soils and high winds poses a significant risk for tree fall. Recent precipitation has already softened the ground, making it easier for tree roots to dislodge during strong gusts. To mitigate this risk:
- Trim dead or weak branches from trees near your home
- Secure outdoor furniture and loose items
- Park vehicles away from trees if possible
- Be prepared for potential power outages due to fallen trees or branches
Farmonaut’s satellite imagery can help identify areas with dense vegetation that may be at higher risk during storms. Check out our

Emergency Kit Essentials
Prepare an emergency kit with the following items:
- Non-perishable food and water for at least 3 days
- Flashlights and extra batteries
- First aid kit
- Battery-powered or hand-crank radio
- Medications and prescription glasses
- Important documents in a waterproof container
- Cash and change
- Warm clothing and blankets
- Personal hygiene items
- Cell phone with chargers and backup battery
Home Preparation
Take these steps to protect your home:
- Clear gutters and downspouts
- Secure or bring in outdoor furniture and decorations
- Trim trees and remove dead branches
- Check sump pumps and backup power sources
- Elevate valuable items in basements or ground floors
- Install or check backflow valves on sewer connections
Flood Safety Tips
Flooding is one of the most significant risks during an atmospheric river event. Follow these safety tips:
- Turn Around, Don’t Drown: Never attempt to drive through flooded roads. Just 6 inches of moving water can knock you down, and 1 foot of water can sweep your vehicle away.
- Stay Informed: Monitor local news and weather reports. Sign up for CruzAware, our county’s emergency alert system, to receive timely notifications.
- Evacuate if Necessary: If authorities issue an evacuation order, leave immediately. Have a plan and know your evacuation route.
- Avoid Flood Waters: Do not walk, swim, or play in flood waters. They may be contaminated or contain dangerous debris.
- Protect Your Health: If you come into contact with flood waters, wash your hands thoroughly. Disinfect items that have touched flood water.

Landslide Awareness
The risk of landslides increases significantly during heavy rainfall events. Be aware of the following warning signs:
- Changes in landscape, such as cracks in the ground or tilting trees
- Doors or windows that suddenly become difficult to open or close
- New springs, seeps, or saturated ground in areas that are usually dry
- Sudden decrease in water levels of streams or creeks
- Unusual sounds like trees cracking or boulders knocking together
If you suspect an imminent landslide, evacuate immediately and contact local authorities.
Coastal Hazards
For our residents along the coast, be prepared for additional challenges:
- Storm Surge: Expect higher-than-normal water levels along the coast, which can lead to flooding and erosion.
- High Surf: Large waves can create dangerous conditions for beachgoers and may cause damage to coastal structures.
- Rip Currents: Strong currents can form, making swimming extremely dangerous.
Stay away from beaches and coastal areas during the storm. If you live in a coastal area, be prepared to evacuate if ordered to do so by local authorities.
Power Outage Preparation
High winds and saturated soils increase the likelihood of power outages. Prepare for potential blackouts by:
- Charging all electronic devices
- Having battery-powered lights and extra batteries on hand
- Keeping refrigerator and freezer doors closed as much as possible
- Using surge protectors to protect sensitive electronic equipment
- Having a battery-powered or hand-crank radio for updates
- Considering a backup power source, such as a generator, for essential medical equipment
Transportation and Road Safety
During the storm, road conditions may become hazardous. Keep these tips in mind:
- Avoid unnecessary travel during the peak of the storm
- If you must drive, reduce speed and increase following distance
- Be prepared for road closures and have alternative routes planned
- Watch for downed power lines and report them to authorities
- Never drive through flooded roads – turn around, don’t drown
Stay updated on road conditions through local news and transportation department websites.
Community Resources and Support
Our community comes together during challenging times. Here are some resources available to Santa Cruz County residents:
- Emergency Shelters: Be aware of designated emergency shelter locations in your area.
- Sandbag Stations: Check with local fire stations or public works departments for sandbag availability.

- Neighborhood Support: Check on elderly neighbors or those with mobility issues who may need assistance.
Remember, we’re all in this together. Offering help to neighbors and staying connected can make a significant difference during severe weather events.
Post-Storm Recovery
After the atmospheric river passes, our community will need to focus on recovery efforts. Here’s what to keep in mind:
- Wait for official all-clear before returning to evacuated areas
- Document any damage to your property for insurance purposes
- Be cautious of standing water, which may be contaminated
- Check for structural damage before re-entering buildings
- Help neighbors with cleanup efforts when it’s safe to do so
- Report downed power lines and stay away from them
