Why do most bad storms move from west to east? The jet stream is the reason they often travel from west to east. Such a stream is a thin band of fast-moving air currents that flow from west to east around the tropopause’s level. The jet stream encircles the entire globe.

Where does most bad weather arrive?

Be particularly aware of weather to the west, the direction from which most bad weather arrives. Watch for fog that creates problems in inlets and bays. Head toward the nearest shore if heavy rain, a thunderstorm, or a hurricane is approaching.

Where do most storms occur?

The Pacific Ocean generates the greatest number of tropical storms and cyclones. The most powerful storms, sometimes called super typhoons, occur in the western Pacific. The Indian Ocean is second in the total number of storms, and the Atlantic Ocean ranks third.
