No, hurricanes normally form over the Atlantic Ocean where there is little to no dust. The white bits you see in satellite photos are just rain clouds formed from the very moist air in the hurricane. When they come ashore they will pickup some dust due to the high-speed winds but they are still mostly made up of rain clouds.
Cumulonimbus clouds
Dust sticks to clouds, because of electricity.
Tornadoes are associated with cumulonimbus clouds, which are tall, dense clouds capable of producing severe weather. Hurricanes are associated with cumulonimbus clouds as well, but they also have a distinct type called the tropical cyclone, characterized by a large circular area of low pressure with spiraling bands of thunderstorms.
Tornadoes develop during thunderstorms, which are themselves giant cumulonimbus clouds. Some tornadoes are produced by hurricanes, but most are not.
clouds of dust and gas
Cumulonimbus clouds are most common in hurricanes. These clouds are large, dense, and capable of producing heavy rainfall and thunderstorms. They are characteristic of the intense convection and strong updrafts found in hurricanes.
they could be dust clouds.
In some cases the clouds in the eyewall can form vertical or nearly vertical walls.
Hurricanes, or clouds
cumulonimbus
Cumulonimbus clouds are typically associated with hurricanes, specifically the towering thunderstorm clouds that produce heavy rain and strong winds within the storm system. In addition, stratocumulus clouds can also be present in the outer bands of a hurricane, contributing to the overall cloud structure of the storm.
There are clouds in both hurricanes and tornadoes. While a hurricane consists of one enormous cloud mass, a tornado consists of a funnel cloud extending from the base of a thunderstorm.
