Our favorite season officially started Monday and is already beginning to create those big dark clouds that peek over the mountains at about 3 p.m. every day.
While you start cheering on the rain, here are some cool facts and tips you need to know about the desert's wet season. Let's start with the fact that about 30-60 percent of Arizona's annual precipitation falls during monsoon season, according to the National Weather Service.
1. When does monsoon start?
Since 2008, the National Weather Service has decreed a monsoon season from June 15 to September 30, but it still keeps track of the monsoon start by a measure it used from 1949 until 2008 — the first of three consecutive days with an average dewpoint of 54 or above.
Also known as chubasco, the summer rains bring much-needed moisture and cooler evenings. Not to mention lightning, heavy rain, high winds, flash flooding, hail and dangerous driving conditions.
2. Driving tips
If you're caught in a severe storm and can’t drive safely, move completely off the road and stop with the lights off. Take your foot off the brake to make sure your brake lights are not lit. This prevents other drivers from following your tail-lights, thinking you're still on the road. Never stop in the travel portion of the road.
Pro tips: Replace your windshield wipers before the monsoons start and be sure to check the weather before traveling.
3. Be safe taking those awesome lightning photos
On average, 47 people die after being struck by lightning in the United States every year, according to the National Weather Service.
Monsoon lovers should take cover when watching storms from afar, most lightning strikes usually occur more than three miles away from the center of the thunderstorm, and have even been spotted as far as 15 miles. Some tips to stay safe during nature’s light show include, stay indoors when you hear thunder, avoid using plumbing and electrical equipment and keep your distance from windows.
4. Watch out for flash flooding
If your neighborhood looks like it's underwater this time of year, there's a good chance it's because of flash flooding. We have floodplains and plenty of roads and washes that fill quickly with excess rainwater during a good storm.
Avoid getting swept away. Flash floods rank at the top of thunderstorm-related deaths, according to the National Weather Service.
Keep away from rivers and washes during heavy rains. If you're driving and see a flooded area, turn around and plan an alternative route. In most cases, it can be difficult to determine how deep the flood is, and moving water as low as one foot has the ability to carry a car.
Arizona's "Stupid Motorist Law" permits rescue agencies to collect up to $2,000 for water rescues if motorists get stuck after purposely driving in flooded areas.
If you're in a house that is prone to flooding, prepare by storing things above flood level and have items like sandbags and plastic sheeting at hand. It's also best to seek higher ground if possible.

5. Get out of those dangerous dust storms
Any big thunderstorm with high winds, much like the ones seen during monsoon season, has the potential to to lift large amounts of dust into the air to form a haboob, or dust storm. And if you've ever seen a photo of an Arizona dust storm, you know they can get intense.
These storms cause problems for motorists as they can happen in a matter of seconds and severely decrease visibility on the road.
The Arizona Department of Transportation recommends that if you find yourself caught in a dust storm, check the vehicles around you and try pulling over to the side of the road as soon as possible. Turn off your lights, stay in the car and keep your seatbelt on until the dust storm passes — this can last anywhere from a few minutes to an hour, according to the National Weather Service.
6. Say hello to your desert neighbors
Expect to see more gila monsters come out to play on nights of high humidity. According to the Arizona-Sonora Desert Museum, gila monsters live in washes that extend down into the valley. They aren't the only ones either, tarantulas and a wide variety of bugs love this time of year too.
Don't freak out, they're just out enjoying the weather like everyone else.
7. Monsoon season scent
Have you ever wondered why it smells so good after a rainy day? The smell actually comes from the creosote bush, which has medicinal properties.
It's a plant unique to the Sonoran Desert in Tucson and other dry regions like the Mohave Desert and the Chihuahuan Desert. The plant releases that familiar musky, earthy smell from a coating on its leaves that helps it conserve water.
Tucsonans love it. It's nostalgic because it smells like monsoon season. Ironically, the Spanish name for creosote is hediondilla, which loosely translates to little stinker.
8. End of Monsoon is the beginning of prickly pear season
With plentiful rain comes the beautiful green vibrancy of the Sonoran Desert and the ruby red fruit of the prickly pear cactus. This unique fruit, called a “tuna” grows from the pads of the cactus, creating an amazing edible crown, that’s ready to harvest in September. Tunas are used in a variety of foods and products, but some of our favorites include the prickly pear margarita, jellies and lip balm.
But we’re getting ahead of ourselves, learn how to harvest them here.
9. It's a great time to collect rainwater
Water from the monsoon storms will definitely fill up those cisterns around town, so much so rainwater collectors can typically use their supplies long after the season is over. If you're interested in setting up your own rainwater collection system, find out how to get started here.
10. You can follow the Tucson Monsoon on Twitter
Yep, this is a thing. And it’s awesome. You can talk one on one with @ElTucsonMonsoon about everything from rain gauges to weather jokes. But mostly it’s a lot of taunting hot Tucsonans.
Now let's stay safe and enjoy the weather.
