DISCUSSION: As what was formerly Tropical Storm Newton earlier this afternoon (but what is now Hurricane Newton) continues its march northward towards the Baja Peninsula and beyond, there will be an increased threat for the commencement of impacts from the North American Monsoon circulation over the next several days. This increased North American Monsoon threat will be the result of impacts from both the inherent moisture advection associated with Hurricane Newton (i.e., eventually Tropical Storm and ultimately Tropical Depression Newton after landfall) and a weak low-pressure system which will become nearly stationary in the coming days across the Four Corners region of the Southwestern United States.
As the aforementioned low-pressure system begins to ingest and interact with the deeper tropical moisture associated with Newton, this will bolster the potential for persistent, heavy rainfall across areas within (but not limited to): Central-to-Eastern Arizona as well as parts of Western New Mexico.
