Quick Answer
A sandstorm is approaching when you notice a decrease in visibility, often accompanied by a change in wind direction and a sudden drop in temperature. Darkening skies and a decrease in humidity are also warning signs. Watch for blowing sand particles that irritate your skin and eyes.
Pre-Storm Signs and Symptoms
A sandstorm often begins with a slight increase in wind speed, usually 15-20 mph (24-32 km/h). As the storm approaches, the wind speed increases, and visibility drops. You may also notice a change in the direction of the wind, often from a gentle breeze to a strong gust. Pay attention to the temperature, which can drop rapidly, especially at night. If you’re planning to venture out, monitor the weather forecast and local reports for any sandstorm warnings.
Identifying Visual Cues
When a sandstorm is approaching, the sky darkens significantly, often taking on a deep grey or brown hue. The sun may appear as a faint disk or be completely obscured by the sand particles. Visibility can drop to as low as 100 yards (91 meters) or less. Look for blowing sand particles that irritate your skin and eyes. If you’re driving, reduce your speed and use low-beam headlights to avoid reducing visibility further.
Preparing for the Storm
If a sandstorm is approaching, seek shelter immediately. Look for a building or a vehicle with a hard top that can provide protection from the wind and sand. If you’re caught outside, wear protective gear such as goggles, a face mask, and long sleeves to reduce skin irritation. Avoid driving through a sandstorm, as reduced visibility can lead to accidents. Stay tuned to local news and weather reports for updates on the storm’s progress and any evacuation orders.
