DENVER (KDVR) — Denver’s weather reached 90 degrees for the first time this year on Wednesday, signaling the onset of summer and the approach of monsoon season in the southwest United States.

As temperatures rise, states like Colorado, Utah, New Mexico, Arizona, and parts of California brace for the arrival of monsoons, characterized by thunderstorms, lightning, heavy rain, and large hail.

Understanding Monsoon Season

The term monsoon originates from the Arabic word mausim, meaning season. Monsoons are driven by a large-scale wind shift between desert regions and tropical areas, a phenomenon observed in various parts of the world.

In the southwest United States, including Colorado, monsoons are fueled by a combination of factors, including:

• Temperature Variation: Before spring, dry subtropical regions experience low-level winds blowing from land to sea. As land temperatures rise, air pressure decreases over land, creating low-pressure areas.
• Moisture Draw: Warmer adjacent bodies of water result in relatively higher air pressure. This pressure gradient draws moist air from the ocean to the hot, dry air over land, leading to atmospheric instability and thunderstorm development.

Impact on Colorado

The monsoon season in Colorado typically spans from June 15 to September 30. During this period, residents can expect regular afternoon thunderstorms, some of which may bring various hazards, including:

• Flash Floods: Sudden heavy rain can lead to flash flooding, particularly in low-lying areas.
• Downburst Winds: Intense, localized bursts of wind can cause damage to property and vegetation.
• Lightning: Thunderstorms are often accompanied by lightning strikes, posing risks to outdoor activities.
• Dust Storms: Dry, dusty conditions may lead to dust storms, reducing visibility on roads.
• Extreme Heat: High temperatures exacerbate the risk of heat-related illnesses.
• Wildfires: Lightning strikes and dry conditions increase the likelihood of wildfires, especially in forested areas.

Preparedness and Safety Measures

To mitigate the risks associated with monsoon season, the National Weather Service recommends the following precautions:

• Stay Informed: Monitor weather forecasts regularly to anticipate upcoming storms and hazards.
• Emergency Preparedness: Have an emergency kit ready, including essentials like water, food, medications, and a flashlight.
• Evacuation Plans: Familiarize yourself with evacuation routes and shelters in your area.
• Property Protection: Secure outdoor furniture, trim trees, and clear gutters to reduce storm-related damage.
• Safety Indoors: During storms, stay indoors and away from windows. Avoid using electrical appliances or plumbing during lightning storms.
• Driving Safety: If driving during a storm, reduce speed, increase following distance, and avoid flooded roads.

Conclusion: Be Weather-Ready with TLNA
