ALBUQUERQUE, N.M. – Storm can hit New Mexico at any time during the year, but one KOB viewer asked why some seem to follow the same path.

"We get so many storms around here," Elisabeth of Rio Rancho said. "So why do they come all from the southwest?"

Storms can come from any direction, but many seem to come from a westerly direction. There is a reason for that. At different latitudes, the Earth has conveyor belts of air which affect weather like the westerlies and the trade winds.

North America is most influenced by the westerlies, which come from the west. Further south toward the equator are the trade winds blowing from the east.

Many factors cause this, including high and low pressure and the spin of the Earth. Many times, the storm track is influenced by the westerlies, which can drive storm systems to New Mexico from the west.

In some cases, major systems that affect New Mexico can start as far away as the Aleutian Islands to the west of Alaska and even Siberia, Russia.
