A haboob is an intense dust storm characterized by strong winds carrying a towering wall of dust and debris. These storms form when powerful downdrafts from thunderstorms strike dry ground, lifting vast amounts of dust. This wall of dust can be miles wide and thousands of feet high, appearing suddenly. The term “haboob” originates from the Arabic word “habb,” meaning “to blow,” and describes the rapid onset of this phenomenon.
Understanding the Threat
Haboobs pose significant hazards, primarily by drastically reducing visibility, often to zero in seconds, making navigation dangerous. Wind speeds can range from 22 to 70 miles per hour, causing damage and lifting debris. Inhaling fine dust particles can lead to respiratory issues, aggravating conditions like asthma and bronchitis. These storms can also carry bacteria, viruses, and fungi, posing additional health risks.
Preparing for a Haboob
Before a haboob strikes, monitor local weather alerts, as warnings are often issued. Secure outdoor items like patio furniture and trash cans to prevent them from becoming airborne projectiles. Close all windows and doors to prevent dust from entering your home. For those in prone areas, prepare an emergency kit with items such as dust masks, water, and a flashlight.
During a Haboob
When a haboob hits, immediate action is necessary. If driving, pull your vehicle off the paved roadway as far as possible, stop, and turn off all lights, including headlights and hazard lights. Keep your foot off the brake pedal to ensure your taillights are not illuminated. This prevents other drivers from colliding with your parked vehicle. Remain inside your vehicle with windows up and seatbelt fastened until the storm passes.
If caught outdoors with no immediate shelter, turn your back to the storm, cover your mouth and nose with a cloth, and protect your eyes with glasses or goggles. If indoors, stay inside, keep windows and doors tightly closed, and consider turning off air conditioning units to prevent dust from entering your home.
After a Haboob
Once a haboob has passed, exercise caution before resuming normal activities. Wait until the dust has settled and visibility has improved, ideally to at least 300 feet, before venturing outside or re-entering the roadway. Check your property for any damage caused by high winds or airborne debris, including windows, roofs, and outdoor structures. Be mindful of potential respiratory issues from residual dust; wearing a mask during cleanup can help protect your lungs. Checking on neighbors can also contribute to community safety.
