Ongoing drought increases danger of haboobs

"If a haboob is approaching, what should you do?

a. Stare

b. Hide

c. Run

Running into a building is the wisest option when faced with a real haboob — a towering wall of sand and dust that blows through arid places, blanketing everything in its path.

The term haboob derives from the Arabic word haab, meaning wind or blow, according to the National Oceanic and Atmospheric Administration. Various dictionaries give the meaning as “strong wind” or “violent storm” from the Arabichabub and hábaa. A true haboob will generate a wall of dust or sand up to 10,000 feet tall and can last 30 minutes or longer, according to NOAA."
