В регионах Каракалпакстан и Хорезм в Узбекистан резко ухудшились погодные условия - поднялся сильный ветер. По данным синоптиков, скорость ветра в отдельных районах достигала 23–25 м/с. Вместе с сильными порывами ветра поднялась пыль, что значительно ухудшило видимость. Специалисты отмечают, что подобные погодные явления часто происходят в межсезонный период.
