Before the storm

Monsoon season officially begins June 15 and Tempe wants to help the community prepare. Tempe encourages residents to take preventative measures towards protecting their property and keeping their family safe 

Storm Preparedness Checklist

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. 

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. Get 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.

High winds

• During a storm, winds can exceed 100 mph and can cause property damage. Make sure you secure any loose items in your yard and trim any overgrown trees.

Dust storms

• When dust storms strike, they can create dangerous driving conditions with zero visibility. Stay inside if you can. If you’re out driving, pull over, put your car in park, turn off all lights, take your foot off the brake and keep your seatbelt on.

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.

• Monsoon brings what we all want – rain! However, heavy rains can lead to flash flooding – so avoid low-water crossings and already flooded areas.
• If your home is prone to flooding, be sure to stop by one of our free sandbag locations – all you’ll need is a shovel.
• 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.

Lightning safety

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:

• Head indoors and seek shelter: a strong building or an enclosed hardtop vehicle works.
• If you’re caught outdoors: do not seek shelter under tall objects, such as trees or light posts.
• 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
• Hydrate yourself, children and pets frequently.
• If you go camping, do not camp in washes.
• Check the weather forecast before heading out.
