Family Disaster Supply Kit
All families should pack a 3-day bag of supplies including: 1 gallon of water per person/pet per day, nonperishable food, flashlights, radio, batteries, medications, first aid kit and a back-up power source for cell phone chargers and medical equipment.
The City of Tempe has sand and bags available at two locations throughout monsoon season (June 15 through Sept. 30). The bags can be picked up 24-hours-a-day, seven-days-a-week. Prior to a major storm event, bags are available on a first-come, first-served basis. Remember to bring a shovel and a helper. The two locations are:
Solid Waste Compost Facility: 1001 N. Rio Road (access drive north of Rio Salado Parkway and Hardy Drive, near free compost)
Benedict Sports Complex: 490 W. Guadalupe Road (northwest corner of Guadalupe and Kyrene roads, east side of parking lot)
Keep storm drains clean of debris
The flooding of streets, sidewalks and homes can be much worse if the city's storm drains are blocked by debris. This can be prevented by disposing of yard waste in trash receptacles. If excessive amounts of debris are collecting near a storm drain, call 480-350-4311. Click here for more stormwater tips.
Prepare your home
- Trim trees so they are away from windows and roofs.
- Clear debris from your roof drainage system, including gutters and downspouts.
- Pre-treat pools with chlorine shock to help prevent algae growth.
- Do not apply fertilizers or other outdoor chemicals before expected storms.
- Secure loose items on your property, such as patio and pool furniture.
- Unplug expensive electronics (TV, stereo, home entertainment centers and computers) and/or install power protection devices.

Current storm information
No storm news at this time.
Flash flood safety
Flash floods are the top thunderstorm-related killer, with most deaths occurring in vehicles. Be sure to avoid flooded areas and low-water crossings.
- Moving water one- to two-feet deep will carry away most vehicles.
- Keep children away from creeks and washes when heavy rain is in the area.
- Be especially careful at night when water depth and road conditions are harder to see.
- Do not play or swim in flooded areas; water may be contaminated with chemicals and bacteria.
- Wash hands and disinfect any items that come in contact with flood waters.
No place outside is safe from lightning during a thunderstorm. Lightning can strike up to 10 miles away from a storm. If you hear thunder, lightning is close enough to strike you. For safety:
- Move inside a strong building or an enclosed hardtop vehicle.
- Avoid contacting inside wiring and plumbing during a thunderstorm; this includes appliances and corded phones.
- Stay in shelter for 30 minutes after the last thunder.
- Call 911 for help immediately if someone is struck by lightning.
Other Safety Tips
- Bring pets indoors because they are likely to panic or run away to escape the storm.
- Avoid downed power lines; call 911 to report them.
- If a power line comes into contact with your vehicle, remain inside the vehicle until help arrives and do not attempt to get out.
- Follow traffic control signs and barricades; if a traffic signal is out, treat the intersection as a 4-way stop
After the storm
If you have experienced dangerous storm activity, such as a downed power line or an injury, call 911. For non-emergencies, call the Tempe Police non-emergency number at 480-350-8311 or call 480-350-4311 from 8 a.m. to 5 p.m., Monday through Friday on non-recognized holidays.
