The Pacific Ocean is deeper than the Atlantic Ocean which causes far more upwelling of cold waters from great depths.
Without the large supply of warm water temperatures in the Pacific, tropical cyclones have a much harder time surviving.
Another contributor is wind direction. From the equator to roughly 30 degrees north the winds travel from east to west.
This is exactly the opposite at Mid Latitudes which is why in the United States weather systems move from west to east.
The winds close to the equator cause tropical cyclones in the Atlantic to typically move toward the East Coast and cyclones in the Pacific typically move away from the West Coast.
