Monsoon Season Preparedness – Yavapai County Office of Emergency Management

As the 2026 monsoon season approaches, local emergency officials are urging residents to prepare for increased storm activity and sudden flooding risks. The Arizona monsoon season officially begins on June 15th and runs through September 30th. Monsoon thunderstorms typically produce half of the annual precipitation for central and northern Arizona. Because these storms develop rapidly, they can cause severe property damage and a sudden onset of flash flooding.

The Yavapai County Office of Emergency Management (YCOEM) and the Yavapai County Flood Control District (YCFCD) remind residents to take proactive steps to protect their homes and families now, especially if they live in low-lying areas or FEMA-designated flood zones.

Because monsoon storms can impact both residential areas and popular outdoor recreation spots, local meteorologists urge extreme caution for those exploring the region’s diverse landscape. “Whether you’re hiking a slot canyon or cooling off by a creek in northern Arizona, always monitor the forecast before heading out, and have a way to receive potentially life-saving weather alerts while in the backcountry,” warns Megan Taylor, Warning Coordination Meteorologist from NWS Flagstaff. “Remember, in areas near fire scars and within canyons, flash floods can happen in minutes. Don’t let a sudden storm catch you off guard!”

Sandbags are a highly effective, low-cost way to protect your home against major sheet-flow and floodwater damage. Yavapai County residents can fill sandbags for free at any of the 23 self-service filling locations positioned across the county. Residents must bring their own shovels, as tools are not provided at the stations. To locate the nearest sandbag-filling site to you, visit www.yavapaiready.gov/sandbags.

Beyond sandbags, residents can significantly reduce their risk by implementing these five safety measures before the first storm hits:

Prepare an Emergency Kit: Build or refresh a disaster supply kit for yourself, your family, and your pets. Don’t forget a 3-to-7-day supply of pet food, medications, and copies of vaccination records.

Clear Property Drainage: Clean out rain gutters, trim trees around your home to prevent wind damage, and inspect or repair roof tiles and shingles.

Know Your Risk: Identify if your home or property sits within a recognized flood zone by entering your address at msc.fema.gov.

Practice Roadway Safety: Never attempt to drive through a flooded wash or roadway. It only takes 12 inches of rushing water to carry away most cars. Remember: Turn Around, Don’t Drown.

Stay Informed: Keep local news and weather alerts handy. Ensure your cell phone is set to receive Wireless Emergency Alerts (WEAs) for your immediate area.

The National Weather Service uses simplified, impact-based language to ensure the public knows exactly when to take action. Familiarize yourself with these core definitions:

• Flood Watch (Be Prepared): Issued when atmospheric conditions are favorable for flooding to develop. It does not mean flooding is guaranteed to happen, but you should have a plan in place and monitor updates.
• Flood/Flash Flood Warning (Take Action!): Issued when dangerous flooding is imminent or already occurring. A Flash Flood Warning means minutes matter. Move to higher ground immediately if you are in a low-lying area.
• Flash Flood: A sudden, violent flood that can take anywhere from a few minutes to a few hours to develop.

Flash flooding can happen incredibly fast, sometimes with little to no warning. You can experience a dangerous flash flood downstream even if it is not raining directly in your immediate area.
