Quick Answer
Evaluate risk by monitoring wind speed, visibility, and sandstorm intensity before venturing outdoors. Check forecasts and warning systems for sandstorm updates. Assess terrain and route conditions to minimize exposure.
Assessing Wind Speed and Visibility
Monitor the wind speed to determine the severity of the sandstorm. Sustained winds of 30-40 mph or higher can reduce visibility to near zero, posing significant risks for outdoor activities. Use a wind speed indicator or consult with local authorities to gauge wind speed. Check visibility by looking at the distance you can see in different directions; a visibility of less than 1/4 mile is considered hazardous.
Analyzing Sandstorm Intensity
Check sandstorm intensity by observing sandblasting, reduced visibility, and wind-borne debris. Sandstorms can be classified into three categories: light (visibility 1-2 miles), moderate (visibility 1/4 to 1 mile), and severe (visibility less than 1/4 mile). If the sandstorm is severe, it may be best to postpone outdoor activities until conditions improve.
Preparing for Terrain and Route Conditions
Assess terrain and route conditions to minimize exposure to sandstorms. Look for areas with dense vegetation, which can provide some protection from sandstorms. Avoid traveling on exposed routes, such as open deserts or sandy roads, during sandstorms. If you must travel, use a four-wheel-drive vehicle or take alternative routes that are less exposed to sandstorms.
