PHOENIX — Firefighters are concerned about new wildfires igniting in the
Southwest during the hot, dry weekend.
National Interagency Fire Center spokeswoman Jennifer Smith says crews are
especially worried about wildfires igniting in the Four Corners region where the
borders of Colorado, New Mexico, Utah and Arizona intersect.
She says some of the strongest parts of a high pressure system are expected to
be parked over the area through the weekend, where forecasters are calling for
lightning but little to no precipitation.
Scientists say that the jet stream, the river of air that dictates weather
patterns, has been more erratic in the past few years. It’s responsible for
weather systems getting stuck, like the current heat wave. Scientists disagree
on whether global warming is the cause of the jet stream’s behavior.
