What causes storms to move east to west?

The easiest answer is the jet stream. In the United States, the wind above our head tends to move in a direction from west to east. These act to steer our storms and move them across the country. As areas of low pressure form, they interact with the jet stream which ultimately pushes them on through.

Why do most hurricanes move from east to west over tropical waters?

(Hurricanes are fueled by warm water as it evaporates off the sea.) In tropical latitudes, nearer the equator, prevailing wind patterns push storms toward the west, because of a high-pressure axis called the subtropical ridge, which extends east-west of the storms. Closer to the equator, general easterly winds prevail.

Farther from the Equator, the surface winds try to blow toward the Poles, but the coriolis effect bends them the opposite direction, creating westerlies. This is why so many weather events in the United States come from the west.

Why are prevailing winds west to east?

Generally, prevailing winds blow east-west rather than north-south. This happens because Earth’s rotation generates what is known as the Coriolis effect. The Coriolis effect makes wind systems twist counter-clockwise in the Northern Hemisphere and clockwise in the Southern Hemisphere.
